What is a literature review? A literature review is a survey of scholarly sources on a specific topic. It provides an overview of current knowledge, allowing you to identify relevant theories, methods, and gaps in the existing research that you can later apply to your paper, thesis, or dissertation topic .

There are five key steps to writing a literature review:

Search for relevant literature
Evaluate sources
Identify themes, debates, and gaps
Outline the structure
Write your literature review

A good literature review doesn’t just summarize sources—it analyzes, synthesizes , and critically evaluates to give a clear picture of the state of knowledge on the subject.

Step 1 & 2

When you write a thesis , dissertation , or research paper , you will likely have to conduct a literature review to situate your research within existing knowledge. The literature review gives you a chance to:

Demonstrate your familiarity with the topic and its scholarly context
Develop a theoretical framework and methodology for your research
Position your work in relation to other researchers and theorists
Show how your research addresses a gap or contributes to a debate
Evaluate the current state of research and demonstrate your knowledge of the scholarly debates around your topic.

Writing literature reviews is a particularly important skill if you want to apply for graduate school or pursue a career in research. We’ve written a step-by-step guide that you can follow below.

Writing literature reviews can be quite challenging! A good starting point could be to look at some examples, depending on what kind of literature review you’d like to write.

Example literature review #1: “Why Do People Migrate? A Review of the Theoretical Literature” ( Theoretical literature review about the development of economic migration theory from the 1950s to today.)
Example literature review #2: “Literature review as a research methodology: An overview and guidelines” ( Methodological literature review about interdisciplinary knowledge acquisition and production.)
Example literature review #3: “The Use of Technology in English Language Learning: A Literature Review” ( Thematic literature review about the effects of technology on language acquisition.)
Example literature review #4: “Learners’ Listening Comprehension Difficulties in English Language Learning: A Literature Review” ( Chronological literature review about how the concept of listening skills has changed over time.)

Before you begin searching for literature, you need a clearly defined topic .

If you are writing the literature review section of a dissertation or research paper, you will search for literature related to your research problem and questions .

Make a list of keywords

Start by creating a list of keywords related to your research question. Include each of the key concepts or variables you’re interested in, and list any synonyms and related terms. You can add to this list as you discover new keywords in the process of your literature search.

Social media, Facebook, Instagram, Twitter, Snapchat, TikTok
Body image, self-perception, self-esteem, mental health
Generation Z, teenagers, adolescents, youth

Search for relevant sources

Use your keywords to begin searching for sources. Some useful databases to search for journals and articles include:

Your university’s library catalogue
Google Scholar
Project Muse (humanities and social sciences)
Medline (life sciences and biomedicine)
EconLit (economics)
Inspec (physics, engineering and computer science)

You can also use boolean operators to help narrow down your search.

Make sure to read the abstract to find out whether an article is relevant to your question. When you find a useful book or article, you can check the bibliography to find other relevant sources.

You likely won’t be able to read absolutely everything that has been written on your topic, so it will be necessary to evaluate which sources are most relevant to your research question.

For each publication, ask yourself:

What question or problem is the author addressing?
What are the key concepts and how are they defined?
What are the key theories, models, and methods?
Does the research use established frameworks or take an innovative approach?
What are the results and conclusions of the study?
How does the publication relate to other literature in the field? Does it confirm, add to, or challenge established knowledge?
What are the strengths and weaknesses of the research?

Make sure the sources you use are credible , and make sure you read any landmark studies and major theories in your field of research.

You can use our template to summarize and evaluate sources you’re thinking about using. Click on either button below to download.

Take notes and cite your sources

As you read, you should also begin the writing process. Take notes that you can later incorporate into the text of your literature review.

It is important to keep track of your sources with citations to avoid plagiarism . It can be helpful to make an annotated bibliography , where you compile full citation information and write a paragraph of summary and analysis for each source. This helps you remember what you read and saves time later in the process.

To begin organizing your literature review’s argument and structure, be sure you understand the connections and relationships between the sources you’ve read. Based on your reading and notes, you can look for:

Trends and patterns (in theory, method or results): do certain approaches become more or less popular over time?
Themes: what questions or concepts recur across the literature?
Debates, conflicts and contradictions: where do sources disagree?
Pivotal publications: are there any influential theories or studies that changed the direction of the field?
Gaps: what is missing from the literature? Are there weaknesses that need to be addressed?

This step will help you work out the structure of your literature review and (if applicable) show how your own research will contribute to existing knowledge.

Most research has focused on young women.
There is an increasing interest in the visual aspects of social media.
But there is still a lack of robust research on highly visual platforms like Instagram and Snapchat—this is a gap that you could address in your own research.

There are various approaches to organizing the body of a literature review. Depending on the length of your literature review, you can combine several of these strategies (for example, your overall structure might be thematic, but each theme is discussed chronologically).

Chronological

The simplest approach is to trace the development of the topic over time. However, if you choose this strategy, be careful to avoid simply listing and summarizing sources in order.

Try to analyze patterns, turning points and key debates that have shaped the direction of the field. Give your interpretation of how and why certain developments occurred.

If you have found some recurring central themes, you can organize your literature review into subsections that address different aspects of the topic.

For example, if you are reviewing literature about inequalities in migrant health outcomes, key themes might include healthcare policy, language barriers, cultural attitudes, legal status, and economic access.

Methodological

If you draw your sources from different disciplines or fields that use a variety of research methods , you might want to compare the results and conclusions that emerge from different approaches. For example:

Look at what results have emerged in qualitative versus quantitative research
Discuss how the topic has been approached by empirical versus theoretical scholarship
Divide the literature into sociological, historical, and cultural sources

Theoretical

A literature review is often the foundation for a theoretical framework . You can use it to discuss various theories, models, and definitions of key concepts.

You might argue for the relevance of a specific theoretical approach, or combine various theoretical concepts to create a framework for your research.

Like any other academic text , your literature review should have an introduction , a main body, and a conclusion . What you include in each depends on the objective of your literature review.

The introduction should clearly establish the focus and purpose of the literature review.

Depending on the length of your literature review, you might want to divide the body into subsections. You can use a subheading for each theme, time period, or methodological approach.

As you write, you can follow these tips:

Summarize and synthesize: give an overview of the main points of each source and combine them into a coherent whole
Analyze and interpret: don’t just paraphrase other researchers — add your own interpretations where possible, discussing the significance of findings in relation to the literature as a whole
Critically evaluate: mention the strengths and weaknesses of your sources
Write in well-structured paragraphs: use transition words and topic sentences to draw connections, comparisons and contrasts

In the conclusion, you should summarize the key findings you have taken from the literature and emphasize their significance.

A literature review is a survey of scholarly sources (such as books, journal articles, and theses) related to a specific topic or research question .

It is often written as part of a thesis, dissertation , or research paper , in order to situate your work in relation to existing knowledge.

There are several reasons to conduct a literature review at the beginning of a research project:

To familiarize yourself with the current state of knowledge on your topic
To ensure that you’re not just repeating what others have already done
To identify gaps in knowledge and unresolved problems that your research can address
To develop your theoretical framework and methodology
To provide an overview of the key findings and debates on the topic

Writing the literature review shows your reader how your work relates to existing research and what new insights it will contribute.

The literature review usually comes near the beginning of your thesis or dissertation . After the introduction , it grounds your research in a scholarly field and leads directly to your theoretical framework or methodology .

A literature review is a survey of credible sources on a topic, often used in dissertations , theses, and research papers . Literature reviews give an overview of knowledge on a subject, helping you identify relevant theories and methods, as well as gaps in existing research. Literature reviews are set up similarly to other academic texts , with an introduction , a main body, and a conclusion .

An annotated bibliography is a list of source references that has a short description (called an annotation ) for each of the sources. It is often assigned as part of the research process for a paper .

Before you begin searching for literature, you need a clearly defined topic .

If you are writing the literature review section of a dissertation or research paper, you will search for literature related to your research objectives and questions .

If you are writing a literature review as a stand-alone assignment, you will have to choose a focus and develop a central question to direct your search. Unlike a dissertation research question, this question has to be answerable without collecting original data. You should be able to answer it based only on a review of existing publications.

Make a list of keywords

Start by creating a list of keywords related to your research topic. Include each of the key concepts or variables you’re interested in, and list any synonyms and related terms. You can add to this list if you discover new keywords in the process of your literature search.

Social media, Facebook, Instagram, Twitter, Snapchat, TikTok
Body image, self-perception, self-esteem, mental health
Generation Z, teenagers, adolescents, youth

You can use boolean operators to help narrow down your search:

Read the abstract to find out whether an article is relevant to your question. When you find a useful book or article, you can check the bibliography to find other relevant sources.

To identify the most important publications on your topic, take note of recurring citations. If the same authors, books or articles keep appearing in your reading, make sure to seek them out.

You probably won’t be able to read absolutely everything that has been written on the topic – you’ll have to evaluate which sources are most relevant to your questions.

For each publication, ask yourself:

What question or problem is the author addressing?
What are the key concepts and how are they defined?
What are the key theories, models and methods? Does the research use established frameworks or take an innovative approach?
What are the results and conclusions of the study?
How does the publication relate to other literature in the field? Does it confirm, add to, or challenge established knowledge?
How does the publication contribute to your understanding of the topic? What are its key insights and arguments?
What are the strengths and weaknesses of the research?

Make sure the sources you use are credible, and make sure you read any landmark studies and major theories in your field of research.

You can find out how many times an article has been cited on Google Scholar – a high citation count means the article has been influential in the field, and should certainly be included in your literature review.

The scope of your review will depend on your topic and discipline: in the sciences you usually only review recent literature, but in the humanities you might take a long historical perspective (for example, to trace how a concept has changed in meaning over time).

How it works

How to Write a Dissertation Literature Review – Steps & Tips

Published by Anastasia Lois at August 12th, 2021 , Revised On October 17, 2023

From an academic standpoint, a dissertation literature review can be defined as a survey of the thesis, journal articles, books, and other academic resources on any given research title . This article provides comprehensive guidelines on how to write a dissertation literature review.

A literature review in a dissertation is of critical importance primarily because it provides insight into the key concepts, advancements, theories, and results of your research questions or research problem .

However, it is essential to note that; a first-class dissertation literature review focuses on summarizing the academic sources used for research and analysing, interpreting, and assessing them to determine the gaps and differences in opinions, judgments, themes, and developments.

A good literature review will further elaborate on existing knowledge concerning the research hypothesis or questions.

View dissertation literature review examples here.

When do you Write a Dissertation Literature Review?

Depending on your university’s guidelines, you might be required to include a literature review in the theoretical framework or the introduction.

Or you could also be asked to develop a standalone literature review chapter that appears before the methodology and the findings chapters of the dissertation.

In either case, your primary aim will be to review the available literature and develop a link between your research and the existing literature on your chosen topic.

Sometimes, you might be designated a literature review as a separate assignment . Regardless of whether you need to write a literature review for your dissertation or as a standalone project, some general guidelines for conducting literature will remain unchanged.

Here are the steps you need to take to write the literature review for a dissertation if you cannot write the literature review.

Steps of Writing a Literature Review

1. gather, assess, and choose relevant literature.

The first seed to take when writing your dissertation or thesis is to choose a fascinating and manageable research topic . Once a topic has been selected, you can begin searching for relevant academic sources.

If you are writing a literature review for your dissertation, one way to do this is to find academic sources relevant to your research problem or questions.

Without fully understanding current knowledge in the chosen study area, giving the correct direction to your research aim and objectives will be hard.

On the other hand, you will be expected to guide your research by developing a central question if you are writing a literature review as an individual assignment.

A notable difference here compared to the dissertation literature review is that you must answer this central question without conducting primary research (questionnaires, surveys, interviews). You will be expected to address the question using only the existing literature.

Use Keywords and References to Find Relevant Literature

Create a list of keywords that are relevant to the topic of research. Find journals, articles, and books using these keywords. Here are links to some recognised online academic libraries and databases;

Inspec, (Computer science, engineering, physics, chemistry)
EconLit, (Economics)
Google Scholar
Your university’s online research database

Finding relevant academic sources from “the reference list” of an article you have already found in a research database effectively discovers relevant studies.

Consider noting frequently appearing references as they are likely to be highly authentic and important publications even though they didn’t appear in the keyword search.

Journal articles or books that keep appearing with different keywords and phrases are the ones you should manually look out for.

The more times an article has been referenced, the more influential it is likely to be in any research field. Google Scholar lets users quickly determine how often a particular article has been referenced.

2. Weighing and Selecting Academic Sources

It won’t be possible for you to read every publication related to your topic. An excellent way to select academic sources for your dissertation literature review is to read the abstract , which will help you decide whether the source is supportive and relevant to your research hypothesis or research questions.

To help you select sources relevant to your study, here are some questions for you to consider before making the decision.

What research questions has the author answered with their research work?
What fundamental concepts have been defined by the author?
Did the researcher use an innovative methodology or existing frameworks to define fundamental methods, models, and theories?
What are the findings, conclusion, and recommendations in the source book or paper?
What is the relevance between the existing literature and the academic sources you are evaluating?
Does the source article challenge, confirm, or add to existing knowledge on the topic?
How does the publication contribute to your understanding of the topic? What are its key insights and arguments?
What are the strengths and weaknesses of the research?

Any breakthrough studies and key theories relevant to your research topic should be recorded as you search for highly credible and authentic academic sources.

The method of your review of literature depends on your academic subject. If your research topic is in the sciences, you must find and review up-to-date academic sources.

On the other hand, you might look into old and historical literature and recent literature if your research topic is in the humanities field.

Recording Information and Referencing Sources

It is recommended that you start to write your literature review as you read articles, journals, and books. Take notes which can be later merged into the text of the literature review. Avoid plagiarism and record all sources used along with references.

A good way of recording information is to analyse each source, summarise the key concepts or theories and compile a complete list of references in the form of an annotated bibliography.

This is a beneficial practice as it helps to remember the key points in each academic source and saves you valuable time as you start the literature review write-up.

3. Identify Key Themes and Patterns

The next step is to look for themes and patterns in the chosen sources that would enable you to establish similarities and differences between their results and interpretations .

This exercise will help you to determine the structure and argument for your literature review. Here are some questions that you can think of when reading and recording information;

Are any gaps in the existing literature?
What are the weaknesses of the current literature that should be addressed?
Were you able to identify any landmark research work and theories that resulted in the topic’s change of direction?
What are the similarities and disagreements between these sources? Were you able to identify any contradictions and conflicts?
What trends and themes were you able to identify? Are there any results, methods, or theories that lost credibility over time?

4. Structure of Literature Review

There is no acclaimed literature review structure , which means that you can choose from a range of approaches (thematic, chronological, methodological, and theoretical) when deciding on the structure of the literature review .

However, before you begin to write the literature review , it is important to figure out the strategy that would work best for you. For long literature reviews, you might decide to use a combination of these strategies. For example, you could discuss each of the themes chronologically.

1: Theoretical

You can discuss various significant concepts, models, and theories in your literature review to form the basis of a theoretical framework . You could also combine a range of theoretical approaches to develop your theoretical framework or debate the significance of a particular theoretical framework.

2: Methodological

The methodological approach will require you to relate the findings of studies conducted in different research areas and use different research methods .

You might discover that results from the quantitative research approach are not the same as qualitative research.
You might split the selected academic sources based on their discipline – engineering, and sciences.

3: Thematic

You may also deploy a thematic approach, especially if you identified repeating key themes and patterns. If that is the case, you will be expected to put each aspect of the topic into different subsections within your literature review.

For example, if your research topic is “employment issues in the UK for international students,” you can divide the key themes into subsections; legal status, poor language skills, immigration policy, and economic turmoil.

4: Chronological

The most straightforward approach is to trace the development of the topic over time. However, if you choose this strategy, avoid simply listing and summarizing sources in order.

Try to analyze patterns, turning points, and critical debates that have shaped the direction of the field. Give your interpretation of how and why certain developments occurred.

5. Writing your Literature Review

Whether it’s a dissertation literature review or a standalone literature review assignment you have been assigned, you will be expected to divide your literature review into three larger sections – introduction, main body, and a conclusion.

What you write under these three segments will depend on the aim of your study.

Section 1 – Introduction

Here you will be required to state the objectives of the literature review clearly;

Introduction to Dissertation Literature Review Recapitulate your research problem or questions with a summary of the sources you reviewed when the literature review is for your thesis or dissertation. Consider highlighting gaps in existing knowledge and stress the suitability of your topic.

For example:

Research problem A has been debated in many recent studies.

While the topic has been explored concerning A, the B aspect has not yet been explored.

Individual Literature Review Project When reviewing literature for an individual literature review assignment, make sure that you clearly state the purpose of the research and debate the scope of the literature (how recent or old are the academic sources you are reviewing).

Section 2 – Main Body

As previously mentioned, you can divide this section into further subsections depending on your literature review’s length. You can also have a separate heading for each research method, theme, or theory to help your readers better understand your research.

Here are some tips for you to write a flawless main body of literature review;

Summarize and Combine ; Highlight the main findings from each academic source and organise them into one whole piece without losing coherence.
Evaluate and interpret; Make sure you are giving opinions and arguments of your own where possible. Simply rephrasing what others have said will undermine your work. You will be expected to debate and discuss other studies’ results about your research questions or aim.
Analytical Evaluation; It is essential to unmistakably present the literature you have reviewed and the merits and weaknesses of the literature.
Make Use of Topic Sentences and Transitions; in organized subsections within the literature review to establish conflicts, differences, similarities, and relationships.

E-recruitment means explicitly using digital technologies to recruit, select, and orient employees. The benefits of e-recruitment in the literature have been studied: increased access to a pool of candidates, time and cost savings, and greater flexibility for the organisation.

In contrast, the literature states that e-recruitment might not properly achieve the goal of retaining the workforce with the required skills to participate in the work environment (Lad & Das, 2016). Also, e-recruitment might be based on a flawed website design or poor application process, which might deter potential employees (Anand & Devi, 2016) .

This section of the study will focus on the existing studies linked to the effectiveness of e-recruitment. Human resource management is an essential function of business organisations because it manages the workforce.

The goal of HR should be to develop a strategic approach in which the organisation’s strategic goals can be attained efficiently and effectively. The advent of digital technologies has helped transform human resource management’s nature concerning recruiting and selecting employees for organisations.

The Internet’s benefits have reduced search time for candidates and significant cost savings for organisations. Finally, it offers a transparent method for obtaining information about specific candidates. E-recruitment helps organisations hire people from any part of the world as it promotes opportunities and benefits the organisation efficiently.

Sharma (2014) argues that 75% of human resource professionals in developed countries are now using e-recruitment to hire employees for their organisations. Additionally, some 2 out of 4 job seekers will use the Internet to source job opportunities.

Another evidence to support the rise of e-recruitment is a study by Holm (2014), which found that all Fortune 100 companies will be using some form of e-recruitment to advertise vacant positions.

The implications are that e-recruitment is a popular strategy for various positions, from blue-collar roles to white-collar and professional positions. The benefits of e-recruitment have been identified in the literature. Girard & Fallery (2009) argues that e-recruitment helps to save time for organisations and employees.

Employers can use several methods to post jobs in as little as 20 minutes. There are no limits to ad size, and they can receive resumes immediately. In contrast, the traditional methods require some time to appear, for example, in a newspaper, and might be there for a limited period.

Section 3 – Conclusion

When writing the dissertation literature review conclusion, you should always include a summary of the key findings which emerged from the literature and their relevance and significance to your research objectives.

Literature Review for Dissertation

If you are writing a dissertation literature review, you will be required to demonstrate how your research helped to fill an evident gap in research and contributed to the current knowledge in the field. Similarly, you can explain how you used the existing patterns, themes, and theories to develop your research framework.

Literature Review as an Individual Assignment

You can summarize your review of your literature’s significance and implications and provide recommendations for future work based on the gaps in existing knowledge you acknowledged.

6. Proofread

Finally, thoroughly proofread your literature review for grammatical, structural, spelling, and factual errors before submitting it to your university.

If you are unable to proofread and edit your paper, then you could take advantage of our editing and proofreading service , which is designed to ensure that your completed literature review satisfies each of your module or project’s requirements. We have Masters and PhD qualified writers in all academic subjects, so you can be confident that they will edit and improve the quality of your to 2:1 or First Class standard, as required.

Valuable Tips for Writing Dissertation Literature Review

Your literature review must systematically comply with your research area. Underneath, we are stating some essential guidelines for a compact literature review.

Contribute to the Literature

After carefully reviewing the literature, search for the gaps in knowledge and state how you have analysed the literature with a different perspective and contributed to your research area.

Keep your Argument Systematic & Consistent

Your arguments must be consistent and systematic while discussing theories and controversial and debatable content. Be logical in your review and avoid vague statements, not to make it complex for the readers.

Provide Adequate References

Don’t forget to provide references, as they are the soul of the dissertation. While discussing different aspects of the research, provide a reasonable number of references, as your discussion and interpretations must be backed up by relevant evidence. You can see an example provided in the sample paragraph above.

Be Precise While Writing a Review

You aren’t required to write every inch of information you have studied while reviewing the literature. You will be able to find tons of information that will correlate with your research area.

Be precise while writing the review, as writing unnecessary, irrelevant information won’t give a good impression. State the most reliable sources in your review without jumping into every possible source.

Don’t go Excessively for Direct Quotes

Direct quoting is required to make a point more impactful, but you should opt for it to a specific limit. Making excessive use of it won’t be a good idea.

The direct quote is mainly used when you think that the words being used by the actual author are so authentic in their meaning that you can’t replace or rephrase them. Try to avoid relying too much on a single author/s work.

Discussing their contributions and keeping the review going briefly would be better. While mentioning the points discussed by the prior researchers – link your arguments with their discussion. Don’t write the crux of their discussion, yet tell if your argument goes along with them.

Express your Analysis

The literature review is written to summarize your perspective, which should be backed up in light of the literature. Critically analyze literature with a rational approach and express your opinion on it.

Use the Correct Referencing Style

While referencing, one must use proper referencing styles, i.e., Harvard reference style, etc. Different referencing styles are used for in-text citations, while different for end-text citations.

Feeling overwhelmed by your literature review? Still unsure about how to write a dissertation literature review? There is no need to panic. Whether you are an undergraduate, postgraduate, or PhD student, our literature review writing service can help you have your literature review to the highest academic quality.

What Is A Literature Review?

A plain-language explainer (with examples).

By: Derek Jansen (MBA) & Kerryn Warren (PhD) | June 2020 (Updated May 2023)

If you’re faced with writing a dissertation or thesis, chances are you’ve encountered the term “literature review” . If you’re on this page, you’re probably not 100% what the literature review is all about. The good news is that you’ve come to the right place.

Example of an actual literature review

What is a literature review?

The word “literature review” can refer to two related things that are part of the broader literature review process. The first is the task of reviewing the literature – i.e. sourcing and reading through the existing research relating to your research topic. The second is the actual chapter that you write up in your dissertation, thesis or research project. Let’s look at each of them:

Reviewing the literature

The first step of any literature review is to hunt down and read through the existing research that’s relevant to your research topic. To do this, you’ll use a combination of tools (we’ll discuss some of these later) to find journal articles, books, ebooks, research reports, dissertations, theses and any other credible sources of information that relate to your topic. You’ll then summarise and catalogue these for easy reference when you write up your literature review chapter.

The literature review chapter

The second step of the literature review is to write the actual literature review chapter (this is usually the second chapter in a typical dissertation or thesis structure ). At the simplest level, the literature review chapter is an overview of the key literature that’s relevant to your research topic. This chapter should provide a smooth-flowing discussion of what research has already been done, what is known, what is unknown and what is contested in relation to your research topic. So, you can think of it as an integrated review of the state of knowledge around your research topic.

Starting point for the literature review

What’s the purpose of a literature review?

The literature review chapter has a few important functions within your dissertation, thesis or research project. Let’s take a look at these:

Purpose #1 – Demonstrate your topic knowledge

The first function of the literature review chapter is, quite simply, to show the reader (or marker) that you know what you’re talking about . In other words, a good literature review chapter demonstrates that you’ve read the relevant existing research and understand what’s going on – who’s said what, what’s agreed upon, disagreed upon and so on. This needs to be more than just a summary of who said what – it needs to integrate the existing research to show how it all fits together and what’s missing (which leads us to purpose #2, next).

Purpose #2 – Reveal the research gap that you’ll fill

The second function of the literature review chapter is to show what’s currently missing from the existing research, to lay the foundation for your own research topic. In other words, your literature review chapter needs to show that there are currently “missing pieces” in terms of the bigger puzzle, and that your study will fill one of those research gaps . By doing this, you are showing that your research topic is original and will help contribute to the body of knowledge. In other words, the literature review helps justify your research topic.

Purpose #3 – Lay the foundation for your conceptual framework

The third function of the literature review is to form the basis for a conceptual framework . Not every research topic will necessarily have a conceptual framework, but if your topic does require one, it needs to be rooted in your literature review.

For example, let’s say your research aims to identify the drivers of a certain outcome – the factors which contribute to burnout in office workers. In this case, you’d likely develop a conceptual framework which details the potential factors (e.g. long hours, excessive stress, etc), as well as the outcome (burnout). Those factors would need to emerge from the literature review chapter – they can’t just come from your gut!

So, in this case, the literature review chapter would uncover each of the potential factors (based on previous studies about burnout), which would then be modelled into a framework.

Purpose #4 – To inform your methodology

The fourth function of the literature review is to inform the choice of methodology for your own research. As we’ve discussed on the Grad Coach blog , your choice of methodology will be heavily influenced by your research aims, objectives and questions . Given that you’ll be reviewing studies covering a topic close to yours, it makes sense that you could learn a lot from their (well-considered) methodologies.

So, when you’re reviewing the literature, you’ll need to pay close attention to the research design , methodology and methods used in similar studies, and use these to inform your methodology. Quite often, you’ll be able to “borrow” from previous studies . This is especially true for quantitative studies , as you can use previously tried and tested measures and scales.

How do I find articles for my literature review?

Finding quality journal articles is essential to crafting a rock-solid literature review. As you probably already know, not all research is created equally, and so you need to make sure that your literature review is built on credible research .

We could write an entire post on how to find quality literature (actually, we have ), but a good starting point is Google Scholar . Google Scholar is essentially the academic equivalent of Google, using Google’s powerful search capabilities to find relevant journal articles and reports. It certainly doesn’t cover every possible resource, but it’s a very useful way to get started on your literature review journey, as it will very quickly give you a good indication of what the most popular pieces of research are in your field.

One downside of Google Scholar is that it’s merely a search engine – that is, it lists the articles, but oftentimes it doesn’t host the articles . So you’ll often hit a paywall when clicking through to journal websites.

Thankfully, your university should provide you with access to their library, so you can find the article titles using Google Scholar and then search for them by name in your university’s online library. Your university may also provide you with access to ResearchGate , which is another great source for existing research.

Remember, the correct search keywords will be super important to get the right information from the start. So, pay close attention to the keywords used in the journal articles you read and use those keywords to search for more articles. If you can’t find a spoon in the kitchen, you haven’t looked in the right drawer.

Need a helping hand?

How should I structure my literature review?

Unfortunately, there’s no generic universal answer for this one. The structure of your literature review will depend largely on your topic area and your research aims and objectives.

You could potentially structure your literature review chapter according to theme, group, variables , chronologically or per concepts in your field of research. We explain the main approaches to structuring your literature review here . You can also download a copy of our free literature review template to help you establish an initial structure.

In general, it’s also a good idea to start wide (i.e. the big-picture-level) and then narrow down, ending your literature review close to your research questions . However, there’s no universal one “right way” to structure your literature review. The most important thing is not to discuss your sources one after the other like a list – as we touched on earlier, your literature review needs to synthesise the research , not summarise it .

Ultimately, you need to craft your literature review so that it conveys the most important information effectively – it needs to tell a logical story in a digestible way. It’s no use starting off with highly technical terms and then only explaining what these terms mean later. Always assume your reader is not a subject matter expert and hold their hand through a journe y of the literature while keeping the functions of the literature review chapter (which we discussed earlier) front of mind.

A good literature review should synthesise the existing research in relation to the research aims, not simply summarise it.

How to write a superb literature review

Andy Tay is a freelance writer based in Singapore.

You can also search for this author in PubMed Google Scholar

Literature reviews are important resources for scientists. They provide historical context for a field while offering opinions on its future trajectory. Creating them can provide inspiration for one’s own research, as well as some practice in writing. But few scientists are trained in how to write a review — or in what constitutes an excellent one. Even picking the appropriate software to use can be an involved decision (see ‘Tools and techniques’). So Nature asked editors and working scientists with well-cited reviews for their tips.

Writing a Literature Review

Welcome to the Purdue OWL

This page is brought to you by the OWL at Purdue University. When printing this page, you must include the entire legal notice.

Copyright ©1995-2018 by The Writing Lab & The OWL at Purdue and Purdue University. All rights reserved. This material may not be published, reproduced, broadcast, rewritten, or redistributed without permission. Use of this site constitutes acceptance of our terms and conditions of fair use.

A literature review is a document or section of a document that collects key sources on a topic and discusses those sources in conversation with each other (also called synthesis ). The lit review is an important genre in many disciplines, not just literature (i.e., the study of works of literature such as novels and plays). When we say “literature review” or refer to “the literature,” we are talking about the research ( scholarship ) in a given field. You will often see the terms “the research,” “the scholarship,” and “the literature” used mostly interchangeably.

Where, when, and why would I write a lit review?

There are a number of different situations where you might write a literature review, each with slightly different expectations; different disciplines, too, have field-specific expectations for what a literature review is and does. For instance, in the humanities, authors might include more overt argumentation and interpretation of source material in their literature reviews, whereas in the sciences, authors are more likely to report study designs and results in their literature reviews; these differences reflect these disciplines’ purposes and conventions in scholarship. You should always look at examples from your own discipline and talk to professors or mentors in your field to be sure you understand your discipline’s conventions, for literature reviews as well as for any other genre.

A literature review can be a part of a research paper or scholarly article, usually falling after the introduction and before the research methods sections. In these cases, the lit review just needs to cover scholarship that is important to the issue you are writing about; sometimes it will also cover key sources that informed your research methodology.

Lit reviews can also be standalone pieces, either as assignments in a class or as publications. In a class, a lit review may be assigned to help students familiarize themselves with a topic and with scholarship in their field, get an idea of the other researchers working on the topic they’re interested in, find gaps in existing research in order to propose new projects, and/or develop a theoretical framework and methodology for later research. As a publication, a lit review usually is meant to help make other scholars’ lives easier by collecting and summarizing, synthesizing, and analyzing existing research on a topic. This can be especially helpful for students or scholars getting into a new research area, or for directing an entire community of scholars toward questions that have not yet been answered.

What are the parts of a lit review?

Most lit reviews use a basic introduction-body-conclusion structure; if your lit review is part of a larger paper, the introduction and conclusion pieces may be just a few sentences while you focus most of your attention on the body. If your lit review is a standalone piece, the introduction and conclusion take up more space and give you a place to discuss your goals, research methods, and conclusions separately from where you discuss the literature itself.

Introduction:

An introductory paragraph that explains what your working topic and thesis is
A forecast of key topics or texts that will appear in the review
Potentially, a description of how you found sources and how you analyzed them for inclusion and discussion in the review (more often found in published, standalone literature reviews than in lit review sections in an article or research paper)
Summarize and synthesize: Give an overview of the main points of each source and combine them into a coherent whole
Analyze and interpret: Don’t just paraphrase other researchers – add your own interpretations where possible, discussing the significance of findings in relation to the literature as a whole
Critically Evaluate: Mention the strengths and weaknesses of your sources
Write in well-structured paragraphs: Use transition words and topic sentence to draw connections, comparisons, and contrasts.

Conclusion:

Summarize the key findings you have taken from the literature and emphasize their significance
Connect it back to your primary research question

How should I organize my lit review?

Lit reviews can take many different organizational patterns depending on what you are trying to accomplish with the review. Here are some examples:

Chronological : The simplest approach is to trace the development of the topic over time, which helps familiarize the audience with the topic (for instance if you are introducing something that is not commonly known in your field). If you choose this strategy, be careful to avoid simply listing and summarizing sources in order. Try to analyze the patterns, turning points, and key debates that have shaped the direction of the field. Give your interpretation of how and why certain developments occurred (as mentioned previously, this may not be appropriate in your discipline — check with a teacher or mentor if you’re unsure).
Thematic : If you have found some recurring central themes that you will continue working with throughout your piece, you can organize your literature review into subsections that address different aspects of the topic. For example, if you are reviewing literature about women and religion, key themes can include the role of women in churches and the religious attitude towards women.
Qualitative versus quantitative research
Empirical versus theoretical scholarship
Divide the research by sociological, historical, or cultural sources
Theoretical : In many humanities articles, the literature review is the foundation for the theoretical framework. You can use it to discuss various theories, models, and definitions of key concepts. You can argue for the relevance of a specific theoretical approach or combine various theorical concepts to create a framework for your research.

What are some strategies or tips I can use while writing my lit review?

Any lit review is only as good as the research it discusses; make sure your sources are well-chosen and your research is thorough. Don’t be afraid to do more research if you discover a new thread as you’re writing. More info on the research process is available in our "Conducting Research" resources .

As you’re doing your research, create an annotated bibliography ( see our page on the this type of document ). Much of the information used in an annotated bibliography can be used also in a literature review, so you’ll be not only partially drafting your lit review as you research, but also developing your sense of the larger conversation going on among scholars, professionals, and any other stakeholders in your topic.

Usually you will need to synthesize research rather than just summarizing it. This means drawing connections between sources to create a picture of the scholarly conversation on a topic over time. Many student writers struggle to synthesize because they feel they don’t have anything to add to the scholars they are citing; here are some strategies to help you:

It often helps to remember that the point of these kinds of syntheses is to show your readers how you understand your research, to help them read the rest of your paper.
Writing teachers often say synthesis is like hosting a dinner party: imagine all your sources are together in a room, discussing your topic. What are they saying to each other?
Look at the in-text citations in each paragraph. Are you citing just one source for each paragraph? This usually indicates summary only. When you have multiple sources cited in a paragraph, you are more likely to be synthesizing them (not always, but often
Read more about synthesis here.

The most interesting literature reviews are often written as arguments (again, as mentioned at the beginning of the page, this is discipline-specific and doesn’t work for all situations). Often, the literature review is where you can establish your research as filling a particular gap or as relevant in a particular way. You have some chance to do this in your introduction in an article, but the literature review section gives a more extended opportunity to establish the conversation in the way you would like your readers to see it. You can choose the intellectual lineage you would like to be part of and whose definitions matter most to your thinking (mostly humanities-specific, but this goes for sciences as well). In addressing these points, you argue for your place in the conversation, which tends to make the lit review more compelling than a simple reporting of other sources.

What is a Literature Review? How to Write It (with Examples)

A literature review is a critical analysis and synthesis of existing research on a particular topic. It provides an overview of the current state of knowledge, identifies gaps, and highlights key findings in the literature. 1 The purpose of a literature review is to situate your own research within the context of existing scholarship, demonstrating your understanding of the topic and showing how your work contributes to the ongoing conversation in the field. Learning how to write a literature review is a critical tool for successful research. Your ability to summarize and synthesize prior research pertaining to a certain topic demonstrates your grasp on the topic of study, and assists in the learning process.

Frequently asked questions

What is a literature review .

A well-conducted literature review demonstrates the researcher’s familiarity with the existing literature, establishes the context for their own research, and contributes to scholarly conversations on the topic. One of the purposes of a literature review is also to help researchers avoid duplicating previous work and ensure that their research is informed by and builds upon the existing body of knowledge.

A literature review serves several important purposes within academic and research contexts. Here are some key objectives and functions of a literature review: 2

1. Contextualizing the Research Problem: The literature review provides a background and context for the research problem under investigation. It helps to situate the study within the existing body of knowledge.

2. Identifying Gaps in Knowledge: By identifying gaps, contradictions, or areas requiring further research, the researcher can shape the research question and justify the significance of the study. This is crucial for ensuring that the new research contributes something novel to the field.

3. Understanding Theoretical and Conceptual Frameworks: Literature reviews help researchers gain an understanding of the theoretical and conceptual frameworks used in previous studies. This aids in the development of a theoretical framework for the current research.

4. Providing Methodological Insights: Another purpose of literature reviews is that it allows researchers to learn about the methodologies employed in previous studies. This can help in choosing appropriate research methods for the current study and avoiding pitfalls that others may have encountered.

5. Establishing Credibility: A well-conducted literature review demonstrates the researcher’s familiarity with existing scholarship, establishing their credibility and expertise in the field. It also helps in building a solid foundation for the new research.

6. Informing Hypotheses or Research Questions: The literature review guides the formulation of hypotheses or research questions by highlighting relevant findings and areas of uncertainty in existing literature.

Literature review example

Let’s delve deeper with a literature review example: Let’s say your literature review is about the impact of climate change on biodiversity. You might format your literature review into sections such as the effects of climate change on habitat loss and species extinction, phenological changes, and marine biodiversity. Each section would then summarize and analyze relevant studies in those areas, highlighting key findings and identifying gaps in the research. The review would conclude by emphasizing the need for further research on specific aspects of the relationship between climate change and biodiversity. The following literature review template provides a glimpse into the recommended literature review structure and content, demonstrating how research findings are organized around specific themes within a broader topic.

Literature Review on Climate Change Impacts on Biodiversity:

Climate change is a global phenomenon with far-reaching consequences, including significant impacts on biodiversity. This literature review synthesizes key findings from various studies:

Climate change-induced alterations in temperature and precipitation patterns contribute to habitat loss, affecting numerous species (Thomas et al., 2004). The review discusses how these changes increase the risk of extinction, particularly for species with specific habitat requirements.

Observations of range shifts and changes in the timing of biological events (phenology) are documented in response to changing climatic conditions (Parmesan & Yohe, 2003). These shifts affect ecosystems and may lead to mismatches between species and their resources.

The review explores the impact of climate change on marine biodiversity, emphasizing ocean acidification’s threat to coral reefs (Hoegh-Guldberg et al., 2007). Changes in pH levels negatively affect coral calcification, disrupting the delicate balance of marine ecosystems.

Recognizing the urgency of the situation, the literature review discusses various adaptive strategies adopted by species and conservation efforts aimed at mitigating the impacts of climate change on biodiversity (Hannah et al., 2007). It emphasizes the importance of interdisciplinary approaches for effective conservation planning.

A literature review is a critical and comprehensive analysis of existing literature (published and unpublished works) on a specific topic or research question and provides a synthesis of the current state of knowledge in a particular field. A well-conducted literature review is crucial for researchers to build upon existing knowledge, avoid duplication of efforts, and contribute to the advancement of their field. It also helps researchers situate their work within a broader context and facilitates the development of a sound theoretical and conceptual framework for their studies.

Literature review is a crucial component of research writing, providing a solid background for a research paper’s investigation. The aim is to keep professionals up to date by providing an understanding of ongoing developments within a specific field, including research methods, and experimental techniques used in that field, and present that knowledge in the form of a written report. Also, the depth and breadth of the literature review emphasizes the credibility of the scholar in his or her field.

Before writing a literature review, it’s essential to undertake several preparatory steps to ensure that your review is well-researched, organized, and focused. This includes choosing a topic of general interest to you and doing exploratory research on that topic, writing an annotated bibliography, and noting major points, especially those that relate to the position you have taken on the topic.

Literature reviews and academic research papers are essential components of scholarly work but serve different purposes within the academic realm. 3 A literature review aims to provide a foundation for understanding the current state of research on a particular topic, identify gaps or controversies, and lay the groundwork for future research. Therefore, it draws heavily from existing academic sources, including books, journal articles, and other scholarly publications. In contrast, an academic research paper aims to present new knowledge, contribute to the academic discourse, and advance the understanding of a specific research question. Therefore, it involves a mix of existing literature (in the introduction and literature review sections) and original data or findings obtained through research methods.

Literature reviews are essential components of academic and research papers, and various strategies can be employed to conduct them effectively. If you want to know how to write a literature review for a research paper, here are four common approaches that are often used by researchers. Chronological Review: This strategy involves organizing the literature based on the chronological order of publication. It helps to trace the development of a topic over time, showing how ideas, theories, and research have evolved. Thematic Review: Thematic reviews focus on identifying and analyzing themes or topics that cut across different studies. Instead of organizing the literature chronologically, it is grouped by key themes or concepts, allowing for a comprehensive exploration of various aspects of the topic. Methodological Review: This strategy involves organizing the literature based on the research methods employed in different studies. It helps to highlight the strengths and weaknesses of various methodologies and allows the reader to evaluate the reliability and validity of the research findings. Theoretical Review: A theoretical review examines the literature based on the theoretical frameworks used in different studies. This approach helps to identify the key theories that have been applied to the topic and assess their contributions to the understanding of the subject. It’s important to note that these strategies are not mutually exclusive, and a literature review may combine elements of more than one approach. The choice of strategy depends on the research question, the nature of the literature available, and the goals of the review. Additionally, other strategies, such as integrative reviews or systematic reviews, may be employed depending on the specific requirements of the research.

The literature review format can vary depending on the specific publication guidelines. However, there are some common elements and structures that are often followed. Here is a general guideline for the format of a literature review: Introduction: Provide an overview of the topic. Define the scope and purpose of the literature review. State the research question or objective. Body: Organize the literature by themes, concepts, or chronology. Critically analyze and evaluate each source. Discuss the strengths and weaknesses of the studies. Highlight any methodological limitations or biases. Identify patterns, connections, or contradictions in the existing research. Conclusion: Summarize the key points discussed in the literature review. Highlight the research gap. Address the research question or objective stated in the introduction. Highlight the contributions of the review and suggest directions for future research.

Both annotated bibliographies and literature reviews involve the examination of scholarly sources. While annotated bibliographies focus on individual sources with brief annotations, literature reviews provide a more in-depth, integrated, and comprehensive analysis of existing literature on a specific topic. The key differences are as follows:

	Annotated Bibliography	Literature Review
Purpose	List of citations of books, articles, and other sources with a brief description (annotation) of each source.	Comprehensive and critical analysis of existing literature on a specific topic.
Focus	Summary and evaluation of each source, including its relevance, methodology, and key findings.	Provides an overview of the current state of knowledge on a particular subject and identifies gaps, trends, and patterns in existing literature.
Structure	Each citation is followed by a concise paragraph (annotation) that describes the source’s content, methodology, and its contribution to the topic.	The literature review is organized thematically or chronologically and involves a synthesis of the findings from different sources to build a narrative or argument.
Length	Typically 100-200 words	Length of literature review ranges from a few pages to several chapters
Independence	Each source is treated separately, with less emphasis on synthesizing the information across sources.	The writer synthesizes information from multiple sources to present a cohesive overview of the topic.

Steps in Conducting a Literature Review

What is a literature review?

A literature review is an integrated analysis -- not just a summary-- of scholarly writings and other relevant evidence related directly to your research question. That is, it represents a synthesis of the evidence that provides background information on your topic and shows a association between the evidence and your research question.

A literature review may be a stand alone work or the introduction to a larger research paper, depending on the assignment. Rely heavily on the guidelines your instructor has given you.

Why is it important?

A literature review is important because it:

Explains the background of research on a topic.
Demonstrates why a topic is significant to a subject area.
Discovers relationships between research studies/ideas.
Identifies major themes, concepts, and researchers on a topic.
Identifies critical gaps and points of disagreement.
Discusses further research questions that logically come out of the previous studies.

APA7 Style resources

APA Style Blog - for those harder to find answers

1. Choose a topic. Define your research question.

Your literature review should be guided by your central research question. The literature represents background and research developments related to a specific research question, interpreted and analyzed by you in a synthesized way.

Make sure your research question is not too broad or too narrow. Is it manageable?
Begin writing down terms that are related to your question. These will be useful for searches later.
If you have the opportunity, discuss your topic with your professor and your class mates.

2. Decide on the scope of your review

How many studies do you need to look at? How comprehensive should it be? How many years should it cover?

This may depend on your assignment. How many sources does the assignment require?

3. Select the databases you will use to conduct your searches.

Make a list of the databases you will search.

Where to find databases:

use the tabs on this guide
Find other databases in the Nursing Information Resources web page
More on the Medical Library web page
... and more on the Yale University Library web page

4. Conduct your searches to find the evidence. Keep track of your searches.

Use the key words in your question, as well as synonyms for those words, as terms in your search. Use the database tutorials for help.
Save the searches in the databases. This saves time when you want to redo, or modify, the searches. It is also helpful to use as a guide is the searches are not finding any useful results.
Review the abstracts of research studies carefully. This will save you time.
Use the bibliographies and references of research studies you find to locate others.
Check with your professor, or a subject expert in the field, if you are missing any key works in the field.
Ask your librarian for help at any time.
Use a citation manager, such as EndNote as the repository for your citations. See the EndNote tutorials for help.

Review the literature

Some questions to help you analyze the research:

What was the research question of the study you are reviewing? What were the authors trying to discover?
Was the research funded by a source that could influence the findings?
What were the research methodologies? Analyze its literature review, the samples and variables used, the results, and the conclusions.
Does the research seem to be complete? Could it have been conducted more soundly? What further questions does it raise?
If there are conflicting studies, why do you think that is?
How are the authors viewed in the field? Has this study been cited? If so, how has it been analyzed?

Tips:

Review the abstracts carefully.
Keep careful notes so that you may track your thought processes during the research process.
Create a matrix of the studies for easy analysis, and synthesis, across all of the studies.

Are you tired of hearing the phrase 'literature review' every five minutes at university and having no idea what it means, let alone where to start? Not to worry - we've got you covered with this step-by-step guide to creating a great dissertation literature review.

What is a literature review?

In short, a dissertation literature review provides a critical assessment of the sources (literature) you have gathered and read surrounding your subject area, and then identifies a “gap” in that literature that your research will attempt to address.

There are a lot of misunderstandings about what exactly a dissertation literature review entails, as it can vary. Whilst in some cases a dissertation literature review can be a simple summary of important sources, most often it requires you to critically engage with the text to convey your positive or negative opinions of it. What is your interpretation of a particular source? Does this interpretation differ considerably from other viewpoints in the literature? This is the sort of critical engagement expected from you in a literature review.

Whereas a summary will most likely provide a simple recap of the general arguments of the source(s), the expectations concerning a literature review extend beyond this. A literature review may provide a new perspective on a classic research paper or it may combine both new and old interpretations (this is the “gap” – more on this later). A literature review may also provide a thorough and critical outline of the intellectual developments in a field with a focus on major, and often polemical, debates. In other scenarios, a literature review may also provide an assessment of a source and inform a reader about its validity, pertinence and relevance to the research subject.

"In a literature review, you're aiming to summarise and provide a critical analysis of the research arguments you have found in your readings, without making new contributions to the literature. Hence the term: “literature review ”."

There tends to be confusion between literature reviews and academic papers in general, but they are not one and the same. Generally, academic papers aim to provide new research material about a particular subject, and a literature review features as part of this objective. In a research paper, the literature review forms the basis of the research – it helps to highlight any research gaps as support for a new argument or insights you intend to provide. In a literature review, you're aiming to summarise and provide a critical analysis of the research arguments you have found in your readings, without making new contributions to the literature. Hence the term: “literature review ”.

Is a literature review really necessary?

Now that we know what a literature review is, the next step is to understand the point of writing one in the first place. Like it or not, a literature review is an essential part of any academic piece of writing, as it demonstrates to your tutor or reader that you have a nuanced understanding of the sources concerning your research area or question.

Although it may seem arbitrary, the literature review helps to persuade the person reading and marking your assignment that what you have written about is relevant and your arguments are justified and worthwhile. So, in short, a literature review is essential, and you need to put the necessary time into getting it right.

How do you write a dissertation literature review?

As the next section of this blog is quite lengthy, we've broken it down into several key steps which should make it easier to follow when writing your own dissertation literature review. You start by identifying your sources, then you read and re-read them. Next, you think about any gaps in the research or literature you have used, and finally, you write your review using all the preparation and information gathered in the steps prior.

Identify sources

To write a good dissertation literature review, you need to have a fair idea of what sources you would like to review. If you haven’t been given a formal reference list by your tutor, refer back to the techniques we recommended earlier.

Make sure that your sources are balanced; include enough books and academic journals and any useful published work from reputable scholars. To help you choose your sources appropriately, you might want to think about the parameters and objectives of your research. What are you hoping to find out? In your literature review , what theoretical issues or perspectives do you aim to tackle? How about your methodology? Will you focus on mainly qualitative or quantitative studies, or a mixture of both? These general questions should help guide you in selecting your sources and again, remember that the abstract of a source is a very useful tool. Having a quick scan of the abstract and its ‘keywords’ will often give you an indication of the whether the source will be useful for your research or not.

As you’re identifying your sources, ensure you a keep a list as it’s very easy to lose focus given the wide scope of the Internet. Reference tools such as Mendeley allow you to store your sources online and via a desktop app, and are a great way to keep your bibliography organised. The citation tools attached to these programmes will also allow you to simply export citations in a format of your choice when required later. They will save you countless hours trying to figure out how to use Harvard or APA referencing correctly.

Read your sources

Now that you have organised your sources efficiently, it’s time to read through them. As unnatural as it may feel, it’s most effective to read in a few stages, as detailed below:

First, go through all the texts to get a sense of their general content and arguments. This will also help you judge which sources you mainly want to focus on in your review. During the second stage of your reading, you can then take a more critical, in-depth look at your sources. Make a lot of notes, be critical, ask questions. What is your academic opinion on the text? Do you have any comments on the methodological approach, the theoretical argument or the general hypothesis? Note these down. It will ensure that your literature review is not merely a summary of your readings, and will encourage a clear line of argument so that your work is logical and coherent.

Consider gaps in the research

When writing a dissertation literature review, an essential thing to consider is identifying the research gap. Identifying the gap is particularly important if your review forms part of a research proposal, as it will highlight the pertinence of your research – assuming that your research has been designed to fill this gap. In other instances, identifying the gap is an indication of good critical analysis and can score you extra points.

To identify the “gap” it is important that we know what this “gap” is. A research gap is essentially the existence of a research question, perspective or problem that has not been answered in the existing literature on any field of study. Identifying the research gap is important for highlighting the originality of your research; it proves you’re not simply recounting or regurgitating existing research. It also shows that you are very much aware of the status of the literature in your chosen field of study, which in turn, demonstrates the amount of research and effort you have put into your review.

Many students, especially at post-graduate level, find it extremely difficult to identify research gaps in their subject area. For post-graduate research papers, identifying research gaps and formulating research questions that can address these gaps form the very essence of a research paper. Identifying research gaps does not have to be a difficult endeavour and there are several ways to overcome this difficulty:

Start by reading A simple approach will be to read important parts of key articles in your research area. First, note that you’ll have to sift through many articles to identify the ones that are most suitable for your research. A quick search using keywords on Google Scholar will often give you a quick overview of the available literature. Other useful sources include databases such as JSTOR or Wiley Online Library . You can then snowball additional articles by clicking on ‘related articles’ or checking out which other papers have cited your source.

Abstracts and recommendations Whichever avenue you choose, reading the abstract is often a good starting point to get a sense of what the articles entails. You should also do a quick examination of the introductory and concluding paragraphs of the paper as these sections always provide some information on the aims and outcomes of the research, as well as ‘recommendations for future studies.’ These recommendations typically provide some insight on the research gaps in the literature. Another route would be to simply read as much as you can on your research subject while considering which research areas still need addressing in the literature – this is usually an indication of research gaps.

Write your review

Now you’re well prepared to start putting fingers to keyboard. Consider the following pointers:

1. Use sample literature reviews Have a look at sample dissertation literature reviews in your subject area and read them thoroughly to familiarise yourself with existing key debates and themes. This can be a good starting point for framing and structuring your own review. If you are not familiar with academic writing, going through samples will help you to get a sense of what is expected in this regard. Pay attention to the academic language and formal style used. Also, remember that the bibliography or reference section of your selected texts will help you to snowball further references if you need any.

2. Keep it simple Keep your topic as narrowed down as possible. Remember that there are hundreds – or in some instances, thousands – of sources or perspectives concerning any subject area or topic. Researchers investigate research problems in many divergent ways and the literature available on any given subject is extremely broad. In your literature review, you won’t be expected to address every argument or perspective concerning your topic – this might actually undermine your ability to write a coherent and focused piece. You’ll make your work easier if you limit the scope of your work. In your review, ensure that you clearly state what the focus of your work will be.

3. Make sure your sources are as current as possible If you are reviewing scientific work, it’s essential your sources are as current as possible given the advancements in the field over the years. In the medical field particularly, research is constantly evolving and a source that’s only three years old may be even out-dated. In the social sciences this rule may not apply, as many theoretical works are classics and you will be expected to be familiar with these perspectives. You might have to the review the work of Marx, or Hobbes, or any other classic scholar. You still need to balance theory with current approaches, as you will need to demonstrate the ways in which perspectives in the literature have changed over the years, or you may even want to demonstrate how scholars have used classic theories to inform their work.

4. Consider the organisation of your work In a dissertation literature review, organising your work goes beyond having an introduction, body and conclusion. You’ll be reviewing a number of texts, so you’ll also have to think clearly about how to organise themes, topics and your argument in general. Below is a detailed guide on how to do this:

Like any other academic paper, a dissertation literature review will comprise a basic introduction, body, and conclusion.

The introduction of a literature review should be clear, short and focused. It should outline the focus of the review – in other words, it should clearly state the main topics to be covered. A good literature review will also state the arguments to be made, as well as underlying rationale that underpins these arguments.

The body of your literature review will include an in-depth discussion of the academic sources you have chosen to review. You may choose to organise your sources according to themes, methodology or even based on a chronological order. In the body of your review, ensure that your arguments are presented clearly and that you link these arguments with the literature. Is there a scholar that agrees with your view? Say so, in a way that the reader will understand easily. This demonstrates that you are very familiar with the academic research in your field. Remember to also make note of any views that do not agree with your position; excluding these arguments will reduce the methodological robustness of your piece. You can use direct quotations in your literature review, however do so sparingly so you don’t appear lazy. Most tutors will not approach it kindly; the purpose of a literature review is to demonstrate your ability to critically engage with a piece of text, and littering your review with direct quotes isn’t a good indication of this. Instead, try to paraphrase quotations and only use direct quotes if it really helps to illustrate your argument.

In the summary of your dissertation literature review, it’s important to give a summary of the conclusions you’ve drawn from your readings. If your literature review forms part of a broader research proposal, reiterate the gaps in the literature here, and clearly state how your proposed research will fill these gaps. Make recommendations for future research in this section too, which demonstrates your analytical skills and will score you some extra points.

You now have the basic structure of your research in place, however it’s worth dedicating some time to what the body of your work should entail. The body is the main core of your work, so it’s important to consider how you will frame and organise it. You have options here – you can choose to organise the content of your work based on a chronological method, based on themes, trends or methodology, or based on arguments.

To structure the body of work chronologically, you will have to organise your sources based on when they were published. A limitation of this approach is that it inhibits continuity in your arguments and in some instances, can undermine the coherence of your work. Use with caution.

A more coherent way of organising your work is to group your sources based on the arguments they make in a ‘for versus against’ manner. This enables you to present your work in a more dynamic way and what’s more, makes the key debates in the literature more obvious. Say you were trying to convey the debates on European migration policy, you might want to start by writing something along these lines:

"While scholars such as X argue that migration policies must be made more stringent to counteract the increased flow of Syrian refugees to Europe, other scholars such as Y offer a divergent perspective. They specifically espouse a perspective based on a human rights approach…"

This approach also leaves room for you to insert your voice into the literature. Consider this statement:

"While X argues for the enactment of more stringent migration policies, this paper argues along the lines of Y that migration policies should be based on human rights considerations."

Using this technique also allows you to introduce additional literature that supports your position.

Another way of organising your content is according to theme; or sub-themes, if your review focuses on one overarching topic. This method of organisation still allows you to present an overview of any polemical debates within these sub-themes. A thematic review can easily shift between chronological periods within each sub-section too.

Structuring work using a methodological approach is quite a common approach, however it’s often used in tandem with other ways of organising sources. This method is particularly evident in introductory sections whereby researchers may simply want to state that a particular subject has been mostly studied from a qualitative or quantitative perspective (they will often then cite a number of scholars or studies to support this claim). In scientific reviews however, a methodological approach may form the basis of the discussions in the body. If this is the case for you, focus on the methods used by various researchers. How did they go about answering a particular research question? Were there any limitations to this method? If so, what method(s) would have been better?

You’ll soon realise that organising the body of your literature review is an iterative process and you’ll more often than not use all of these approaches in your write-up. The body of your research may also include additional sections that do not necessarily form a part of its organisational structure. For instance, you might want to include a ‘context section’ that provides some insight on any background detail required for understanding the focus of the literature review. It may also focus on historical considerations. You could include a short methodology section that details the approach you used in selecting and analysing your sources.

5. Write the paragraphs of the body Once you have settled on the approach to writing your body, you must now write each of its paragraphs in a way that is in keeping with academic conventions. Consider this paragraph from a literature review about stakeholder participation for environmental management, to clarify the discussion that follows:

Despite the rhetoric and the concerns that have been expressed, there have been few attempts to investigate the validity of the many claims that have been made for stake-holder participation (Webler, 1999; Beierle, 2002; Brody, 2003; Blackstock et al., 2007). The few attempts that have been made have tended to focus on evaluating the process rather than the outcomes (e.g. Beierle, 2002; Renn et al., 1995; Rowe and Frewer, 2000). This may be partly due to the challenge of selecting appropriate evaluation criteria and data collection methods. Blackstock et al., 2007 argue that the evaluation of participatory processes should itself be participatory, with stakeholders selecting and applying the evaluation criteria. However, this is not straightforward. Webler and Tuler (2006) found strong differences of opinion between participants that they selected from ten case studies, about what constituted a "good" participatory process. (Source: Reed, M.S., 2008. Stakeholder participation for environmental management: a literature review. Biological conservation, 141(10), pp.2417-2431).

As the example above suggests, a dissertation literature review must be written using a formal and academic style . Also, note how sources have been grouped according to both arguments and themes. Remember we noted that the process of grouping sources in the body of your literature review is never a linear one? You will often use a combination of the approaches that we have discussed. Ensure that your writing is concise, coherent and devoid of any personal or strong language. Avoid any phrases like, “I hate X’s work”; a more academic way of stating your disagreement would be to simply state: “I would argue against X’s position that…”, or “X’s argument is inconsistent with the evidence because...”, or “X’s arguments are based on false assumptions because...”.

In the sample paragraph above, notice the use of words like “argue” – this is a good academic alternative to more commonplace words such as “says”. Other good alternatives include “states”, “asserts”, “proposes” or “claims”. More academic options include “opine”, “posit”, “postulate”, or “promulgate”, however some tutors and readers find these words to be too ‘heavy’ and archaic, so ensure that you are familiar with the writing standards in your institution.

If your writing is tailored to a peer-reviewed journal, it’s worth having a look at articles within that journal to get a sense of the writing style. Most tutors will provide a guideline on writing styles, and it’s important you adhere to this brief. You will often be required to also use the third person when writing a literature review, thus phrases such as “this paper argues” or “this paper is of the view that…” are appropriate.

There are exceptions at post-graduate level or generally – like when you have conducted your own primary research or published your work widely – which give you the academic authority to boldly make claims. In cases like these, the use of first person is suitable and you may use phrases such as “I argue” or “I propose”.

Remember also to generally use present tense when referring to opinions and theories (although in the context of specific research experiments, the use of the past tense is better).

Beyond the use of the academic terms suggested above, ‘linking’ words are also particularly important when writing a literature review, since you’ll be grouping a lot of writers together with either similar or divergent opinions. Useful linking words and phrases include: similarly, there are parallels, in convergence with…

When there is disagreement, you may want to use any of the following: However, conversely, on the other hand, diverges from, antithetical to, differential from…

6. Write the conclusion The conclusion of a dissertation literature review should always include a summary of the implications of the literature, which you should then link to your argument or general research question.

Some final notes

The overall structure of your literature review will be largely based on your research area and the academic conventions that are in line with it. Nevertheless, there are some essential steps that apply across all disciplines and that you should ensure you follow:

Do not simply describe the opinions of writers Analyse, analyse, analyse, and ensure that your analysis is critical (what have the writers missed; where does your opinion sit with theirs, etc.).

Structure the body of your argument using various techniques Your structure should be organised based on thematic areas, key debates or controversial issues, and according to methodological approaches. Keep your review dynamic, but coherent. Remember to identify literature gaps and link this to your own research.

Use ample evidence This is extremely important and forms the very essence of a dissertation literature review. You must refer to various sources when making a point; see the sample paragraph above for an example of this. Your arguments and interpretation of a research topic must be backed by evidence. Do not make baseless claims, as a literature review is an academic piece of writing and not an opinion piece.

Be very selective Not every piece of research has to be reviewed. If you are determined to show that you aware of the available literature out there, try writing techniques such as: There is robust literature available concerning the migration patterns of Syrian refugees. Notable works include: X(2015), y (2013), Z (2014). Once you have acknowledged these works, you do not have to review them in detail. Be selective about the sources that you will discuss in detail in your review.

Do not rely too much on direct quotes Only use them to emphasise a point. Similarly, don’t rely too heavily on the work of a single author. Instead, highlight the importance of that author in your research and move on. If you need to keep going back to the work of that author, then you need to link those discussions with your work. Do not simply provide a summary of the author’s work. In what ways does your work agree or disagree with his/hers? Be critical.

Make your voice heard Yes, the whole point of the literature review is to provide a critical analysis and summary of the viewpoints out there, but a critical analysis does include the fact that you need to make your opinion known in the context of the literature. Note how skilfully, in the earlier sample paragraph by Reed (2008), he weaves his opinions with references. Read back over the sample and try to perfect this skill.

Ensure that you reference your work correctly And make sure you use the appropriate referencing style. For more help on this, click here .

How to write a literature review for a dissertation, published by steve tippins on july 5, 2019 july 5, 2019.

Last Updated on: 22nd May 2024, 04:06 am

Chapter 2 of your dissertation, your literature review, may be the longest chapter. It is not uncommon to see lit reviews in the 40- to 60-page range. That may seem daunting, but I contend that the literature review could be the easiest part of your dissertation.

It is also foundational. To be able to select an appropriate research topic and craft expert research questions, you’ll need to know what has already been discovered and what mysteries remain.

Remember, your degree is meant to indicate your achieving the highest level of expertise in your area of study. The lit review for your dissertation could very well form the foundation for your entire career.

In this article, I’ll give you detailed instructions for how to write the literature review of your dissertation without stress. I’ll also provide a sample outline.

When to Write the Literature Review for your Dissertation

Though technically Chapter 2 of your dissertation, many students write their literature review first. Why? Because having a solid foundation in the research informs the way you write Chapter 1.

Also, when writing Chapter 1, you’ll need to become familiar with the literature anyway. It only makes sense to write down what you learn to form the start of your lit review.

Some institutions even encourage students to write Chapter 2 first. But it’s important to talk with your Chair to see what he or she recommends.

How Long Should a Literature Review Be?

There is no set length for a literature review. The length largely depends on your area of study. However, I have found that most literature reviews are between 40-60 pages.

If your literature review is significantly shorter than that, ask yourself (a) if there is other relevant research that you have not explored, or (b) if you have provided enough of a discussion about the information you did explore.

Preparing to Write the Literature Review for your Dissertation

Step 1. Search Using Key Terms

Most people start their lit review searching appropriate databases using key terms. For example, if you’re researching the impact of social media on adult learning, some key terms you would use at the start of your search would be adult learning, androgogy, social media, and “learning and social media” together.

If your topic was the impact of natural disasters on stock prices, then you would need to explore all types of natural disasters, other market factors that impact stock prices, and the methodologies used.

You can save time by skimming the abstracts first; if the article is not what you thought it might be you can move on quickly.

Once you start finding articles using key terms, two different things will usually happen: you will find new key terms to search, and the articles will lead you directly to other articles related to what you are studying. It becomes like a snowball rolling downhill.

Note that the vast majority of your sources should be articles from peer-reviewed journals.

Step 2. Immerse Yourself in the Literature

woman asleep on the couch next to a giant pile of books

When people ask what they should do first for their dissertation the most common answer is “immerse yourself in the literature.” What exactly does this mean?

Think of this stage as a trip into the quiet heart of the forest. Your questions are at the center of this journey, and you’ll need to help your reader understand which trees — which particular theories, studies, and lines of reasoning — got you there.

There are lots of trees in this particular forest, but there are particular trees that mark your path. What makes them unique? What about J’s methodology made you choose that study over Y’s? How did B’s argument triumph over A’s, thus leading you to C’s theory?

You are showing your reader that you’ve fully explored the forest of your topic and chosen this particular path, leading to these particular questions (your research questions), for these particular reasons.

Step 3. Consider Gaps in the Research

The gaps in the research are where current knowledge ends and your study begins. In order to build a case for doing your study, you must demonstrate that it:

Is worthy of doctoral-level research, and
Has not already been studied

Defining the gaps in the literature should help accomplish both aims. Identifying studies on related topics helps make the case that your study is relevant, since other researchers have conducted related studies.

And showing where they fall short will help make the case that your study is the appropriate next step. Pay special attention to the recommendations for further research that the authors of studies make.

Step 4. Organize What You Find

As you find articles, you will have to come up with methods to organize what you find.

Whether you find a computer-based system (three popular systems are Zotero, endNote, and Mendeley) or some sort of manual system such as index cards, you need to devise a method where you can easily group your references by subject and methodology and find what you are looking for when you need it. It is very frustrating to know you have found an article that supports a point that you are trying to make, but you can’t find the article!

One way to save time and keep things organized is to cut and paste relevant quotations (and their references) under topic headings. You’ll be able to rearrange and do some paraphrasing later, but if you’ve got the quotations and the citations that are important to you already embedded in your text, you’ll have an easier time of it.

If you choose this method, be sure to list the whole reference on the reference/bibliography page so you don’t have to do this page separately later. Some students use Scrivener for this purpose, as it offers a clear way to view and easily navigate to all sections of a written document.

How to Write the Literature Review for your Dissertation

Once you have gathered a sufficient number of pertinent references, you’ll need to string them together in a way that tells your story. Explain what previous researchers have done by telling the story of how knowledge on this topic has evolved. Here, you are laying the support for your topic and showing that your research questions need to be answered. Let’s dive into how to actually write your dissertation’s literature review.

Step 1. Create an Outline

If you’ve created a system for keeping track of the sources you’ve found, you likely already have the bones of an outline. Even if not, it may be relatively easy to see how to organize it all. The main thing to remember is, keep it simple and don’t overthink it. There are several ways to organize your dissertation’s literature review, and I’ll discuss some of the most common below:

By topic. This is by far the most common approach, and it’s the one I recommend unless there’s a clear reason to do otherwise. Topics are things like servant leadership, transformational leadership, employee retention, organizational knowledge, etc. Organizing by topic is fairly simple and it makes sense to the reader.
Chronologically. In some cases, it makes sense to tell the story of how knowledge and thought on a given subject have evolved. In this case, sub-sections may indicate important advances or contributions.
By methodology. Some students organize their literature review by the methodology of the studies. This makes sense when conducting a mixed-methods study, and in cases where methodology is at the forefront.

Step 2. Write the Paragraphs

I said earlier that I thought the lit review was the easiest part to write, and here is why. When you write about the findings of others, you can do it in small, discrete time periods. You go down the path awhile, then you rest.

Once you have many small pieces written, you can then piece them together. You can write each piece without worrying about the flow of the chapter; that can all be done at the end when you put the jigsaw puzzle of references together.

Step 3. Analyze

The literature review is a demonstration of your ability to think critically about existing research and build meaningfully on it in your study. Avoid simply stating what other researchers said. Find the relationships between studies, note where researchers agree and disagree, and– especiallyy–relate it to your own study.

Pay special attention to controversial issues, and don’t be afraid to give space to researchers who you disagree with. Including differing opinions will only strengthen the credibility of your study, as it demonstrates that you’re willing to consider all sides.

Step 4. Justify the Methodology

In addition to discussing studies related to your topic, include some background on the methodology you will be using. This is especially important if you are using a new or little-used methodology, as it may help get committee members onboard.

I have seen several students get slowed down in the process trying to get committees to buy into the planned methodology. Providing references and samples of where the planned methodology has been used makes the job of the committee easier, and it will also help your reader trust the outcomes.

Advice for Writing Your Dissertation’s Literature Review

Remember to relate each section back to your study (your Problem and Purpose statements).
Discuss conflicting findings or theoretical positions. Avoid the temptation to only include research that you agree with.
Sections should flow together, the way sections of a chapter in a nonfiction book do. They should relate to each other and relate back to the purpose of your study. Avoid making each section an island.
Discuss how each study or theory relates to the others in that section.
Avoid relying on direct quotes–you should demonstrate that you understand the study and can describe it accurately.

Sample Outline of a Literature Review (Dissertation Chapter 2)

Here is a sample outline, with some brief instructions. Note that your institution probably has specific requirements for the structure of your dissertation’s literature review. But to give you a general idea, I’ve provided a sample outline of a dissertation ’s literature review here.

Introduction
State the problem and the purpose of the study
Give a brief synopsis of literature that establishes the relevance of the problem
Very briefly summarize the major sections of your chapter

Documentation of Literature Search Strategy

Include the library databases and search engines you used
List the key terms you used
Describe the scope (qualitative) or iterative process (quantitative). Explain why and based on what criteria you selected the articles you did.

See below for an example of what this outline might look like.

How to Write a Literature Review for a Dissertation: An Example

Let’s take an example that will make the organization, and the outline, a little bit more clear. Below, I’ll fill out the example outline based on the topics discussed.

If your questions have to do with the impact of the servant leadership style of management on employee retention, you may want to saunter down the path of servant leadership first, learning of its origins , its principles , its values , and its methods .

You’ll note the different ways the style is employed based on different practitioners’ perspectives or circumstances and how studies have evaluated these differences. Researchers will draw conclusions that you’ll want to note, and these conclusions will lead you to your next questions.

Next, you’ll want to wander into the territory of management styles to discover their impact on employee retention in general. Does management style really make a difference in employee retention, and if so, what factors, exactly, make this impact?

Employee retention is its own path, and you’ll discover factors, internal and external, that encourage people to stick with their jobs.

You’ll likely find paradoxes and contradictions in here that just bring up more questions. How do internal and external factors mix and match? How can employers influence both psychology and context ? Is it of benefit to try and do so?

At first, these three paths seem somewhat remote from one another, but your interest is where the three converge. Taking the lit review section by section like this before tying it all together will not only make it more manageable to write but will help you lead your reader down the same path you traveled, thereby increasing clarity.

Example Outline

So the main sections of your literature review might look something like this:

Literature Search Strategy
Conceptual Framework or Theoretical Foundation
Literature that supports your methodology
Origins, principles, values
Seminal research
Current research
Management Styles’ Impact on employee retention
Internal Factors
External Factors
Influencing psychology and context
Summary and Conclusion

Final Thoughts on Writing Your Dissertation’s Chapter 2

The lit review provides the foundation for your study and perhaps for your career. Spend time reading and getting lost in the literature. The “aha” moments will come where you see how everything fits together.

At that point, it will just be a matter of clearly recording and tracing your path, keeping your references organized, and conveying clearly how your research questions are a natural evolution of previous work that has been done.

Developing a Literature Review

1. Purpose and Scope

To help you develop a literature review, gather information on existing research, sub-topics, relevant research, and overlaps. Note initial thoughts on the topic - a mind map or list might be helpful - and avoid unfocused reading, collecting irrelevant content. A literature review serves to place your research within the context of existing knowledge. It demonstrates your understanding of the field and identifies gaps that your research aims to fill. This helps in justifying the relevance and necessity of your study.

To avoid over-reading, set a target word count for each section and limit reading time. Plan backwards from the deadline and move on to other parts of the investigation. Read major texts and explore up-to-date research. Check reference lists and citation indexes for common standard texts. Be guided by research questions and refocus on your topic when needed. Stop reading if you find similar viewpoints or if you're going off topic.

You can use a "Synthesis Matrix" to keep track of your reading notes. This concept map helps you to provide a summary of the literature and its connections is produced as a result of this study. Utilizing referencing software like RefWorks to obtain citations, you can construct the framework for composing your literature evaluation.

2. Source Selection

Focus on searching for academically authoritative texts such as academic books, journals, research reports, and government publications. These sources are critical for ensuring the credibility and reliability of your review.

Academic Books: Provide comprehensive coverage of a topic.
Journal Articles: Offer the most up-to-date research and are essential for a literature review.
Research Reports: Detailed accounts of specific research projects.
Government Publications: Official documents that provide reliable data and insights.

3. Thematic Analysis

Instead of merely summarizing sources, identify and discuss key themes that emerge from the literature. This involves interpreting and evaluating how different authors have tackled similar issues and how their findings relate to your research.

4. Critical Evaluation

Adopt a critical attitude towards the sources you review. Scrutinize, question, and dissect the material to ensure that your review is not just descriptive but analytical. This helps in highlighting the significance of various sources and their relevance to your research.

Each work's critical assessment should take into account:

Provenance: What qualifications does the author have? Are the author's claims backed up by proof, such as first-hand accounts from history, case studies, stories, statistics, and current scientific discoveries? Methodology: Were the strategies employed to locate, collect, and evaluate the data suitable for tackling the study question? Was the sample size suitable? Were the findings properly reported and interpreted? Objectivity : Is the author's viewpoint impartial or biased? Does the author's thesis get supported by evidence that refutes it, or does it ignore certain important facts? Persuasiveness: Which of the author's arguments is the strongest or weakest in terms of persuasiveness? Value: Are the author's claims and deductions believable? Does the study ultimately advance our understanding of the issue in any meaningful way?

5. Categorization

Organize your literature review by grouping sources into categories based on themes, relevance to research questions, theoretical paradigms, or chronology. This helps in presenting your findings in a structured manner.

6. Source Validity

Ensure that the sources you include are valid and reliable. Classic texts may retain their authority over time, but for fields that evolve rapidly, prioritize the most recent research. Always check the credibility of the authors and the impact of their work in the field.

7. Synthesis and Findings

Synthesize the information from various sources to draw conclusions about the current state of knowledge. Identify trends, controversies, and gaps in the literature. Relate your findings to your research questions and suggest future directions for research.

Practical Tips

Use a variety of sources, including online databases, university libraries, and reference lists from relevant articles. This ensures a comprehensive coverage of the literature.
Avoid listing sources without analysis. Use tables, bulk citations, and footnotes to manage references efficiently and make your review more readable.
Writing a literature review is an ongoing process. Start writing early and revise as you read more. This iterative process helps in refining your arguments and identifying additional sources as needed.

Co-witnesses and the effects of discussion on eyewitness memory by Helen M Paterson

Overview of thesis (introduction)

This introductory section is less than two pages long.

The first paragraph:

states the overall objective of the thesis
defines the introduced term
provides broad motivation for interest in the area
introduces the sections of the thesis that will address the overall objective.

The other paragraphs describe the content and purpose of each section of the thesis.

Literature review

The literature review is made of up of two chapters.

Chapter 1: Literature review of relevant research

The overall goals of this chapter are to firstly establish the significance of the general field of study, and then identify a place where a new contribution could be made.

The bulk of the chapter critically evaluates the methodologies used in this field to identify the appropriate approach for investigating the research questions.

Purpose	Example
Establish research territory	“Approximately 77,000 individuals are arrested in the United States each year based primarily on eyewitness testimony (ref.). … the pivotal role that eyewitness testimony plays in some trials, whether or not the jury’s faith in this testimony is warranted.”
Establish significance of research territory	“One study has shown that eyewitness errors are the most common cause of false convictions (ref.). Almost all innocent individuals exonerated by DNA evidence had been convicted primarily as a result of erroneous eyewitness evidence (ref.) , a great deal of research has focussed on the unreliability of eyewitness testimony (refs.).”
Establish research niche – discusses what has been found then identifies a gap and points out the inconsistency of results	“The current thesis examines the third way that postevent misinformation may be encountered: through other witnesses. , as the majority of the literature on eyewitness testimony has focussed on the effect of questions and media reports containing misleading information.”
Motivate the next part of literature review	“Yarmey and Morris (1998) suggest that, ‘The capricious results among these investigations are probably due to methodological differences and variability in subject matter’ (p. 1638). co-witness information on eyewitness reports, , in detail, the different methodologies that have been used to investigate this topic.”
Further justify the need to investigate the impact of social influences on memory	“ , researchers in memory have aimed to keep procedures free from contamination, such as other people’s memories (ref.). , such a narrow focus may not fully explain how people remember (ref.). Because such ‘contamination’ is common to memory, understanding its effects enables greater knowledge of memory itself (ref.). … , instead of intentionally avoiding the social aspects of memory, they should be explored in their own right.”
Review the chronological development of research in this area (a chronological approach may not always be appropriate) Discuss one key paper at a time and for each paper:	“ the above studies provide valuable information regarding the social aspects of memory, exercised before applying these results to the judicial area. the results obtained from studies using stories and word lists as stimuli can be generalised to forensic contexts.” … “That is, the differences found between individuals and groups could simply be due to the participants giving their reports for a second time …” … “ on collaborative memory is that the memory of groups is compared with that of individuals. … group performance should not be compared with individual performance but rather with ‘nominal groups’ comprised of pooled, non-redundant data from the same number of people tested individually.”
Overall conclusion or summary that states why a particular methodological approach has been chosen	“… Most research involving the Experimentally Induced Information methodology seeks to identify the influence of misinformation presented by one witness to another, and therefore the assumption is made that discussion between witnesses is a detrimental process. to also investigate the effects of co-witness information using Natural Discussion Groups . , few studies have used this methodology, and those that have, have yielded mixed findings. , future investigation using the Natural Discussion Group methodology would be helpful to better understand the effects of discussion on memory.”

Chapter 2: Theoretical explanations of memory conformity


Establish a reason for this chapter and state the purpose	“While the misinformation effect is a well-established phenomenon, ‘what remains in dispute is the nature of a satisfactory theoretical explanation’ (ref.). … Therefore, memory conformity occurs, we must draw from both cognitive research on memory and social research on conformity. In this section, relevant cognitive and social theories are discussed (1) explain the occurrence of memory conformity and (2) describe factors that influence memory conformity.”
Introduction/overview of the structure of the review	“Four distinct explanations have been offered for the memory conformity effect: (1) … The empirical evidence relevant to each of these explanations is reviewed in this section.”
Discuss each of the four explanations using the following structure:	“ normative social influence the conformity that occurs in …, memory conformity that may occur when people give individual statements following discussion in the absence of their co-witness. ( )”
Compare explanations and draw synthesised conclusions	“The suggestion that memory conformity is a result of biased guessing the informational influence explanation because in both instances … , the feature between the two explanations is that …” … “Whilst biased guessing account for the misinformation effect that occurs in some instances (refs.), research suggests that it is not the only reason for the occurrence of the misinformation effect. ( ) … the misinformation effect may be due memory impairment, rather than just biased guessing.”
	“Informational influence, biased guessing, and modification of memory may help to explain why memory conformity occurs when participants are tested individually, . … these alternative explanations which best explains memory conformity in individual recall following co-witness discussion. ( )”
Discuss methodological issues in achieving aim	“One way to determine whether memory conformity occurs because of biased guessing is to …” “Experiments described in this thesis (Studies 5-7) include a warning for some participants about possible misinformation whether participants report misinformation because of informational influence or memory change.”
Introduce another question of interest and review what has been found so far	“ it has been shown that in some circumstances many people tend to conform to the opinions of others, that some people are able to resist conforming in some situations. For example, … This section of the literature review examines factors influencing whether or not a person is likely to conform that are (1) in the situation, and (2) within the individual.”
Clarify the relevance to the thesis	“Although the experiments described in this thesis do not attempt to manipulate and test the factors that influence conformity, the results obtained and of the findings.”

Chapter 5, Study 3: Co-Witness Contamination

This chapter has the following structure:

Introduction
Discussion.

The introduction introduces the particular study to be reported on, and includes a three-and-a-half page literature review.

The literature review in this chapter:

links back to the relevant general findings of the earlier literature review chapters
briefly reviews the broad motivation for this study
identifies that two previously used methodologies in this field will be compared to resolve questions about the findings of previous studies which had only used a single methodology
uses previous literature to generate specific hypotheses to test
reviews additional literature to provide a justification for a second objective to be investigated in the study reported on in this chapter.

How to write a literature review introduction (+ examples)

The introduction to a literature review serves as your reader’s guide through your academic work and thought process. Explore the significance of literature review introductions in review papers, academic papers, essays, theses, and dissertations. We delve into the purpose and necessity of these introductions, explore the essential components of literature review introductions, and provide step-by-step guidance on how to craft your own, along with examples.

Why you need an introduction for a literature review

In academic writing , the introduction for a literature review is an indispensable component. Effective academic writing requires proper paragraph structuring to guide your reader through your argumentation. This includes providing an introduction to your literature review.

It is imperative to remember that you should never start sharing your findings abruptly. Even if there isn’t a dedicated introduction section .

When you need an introduction for a literature review

There are three main scenarios in which you need an introduction for a literature review:

What to include in a literature review introduction

It is crucial to customize the content and depth of your literature review introduction according to the specific format of your academic work.

In practical terms, this implies, for instance, that the introduction in an academic literature review paper, especially one derived from a systematic literature review , is quite comprehensive. Particularly compared to the rather brief one or two introductory sentences that are often found at the beginning of a literature review section in a standard academic paper. The introduction to the literature review chapter in a thesis or dissertation again adheres to different standards.

Academic literature review paper

The introduction of an academic literature review paper, which does not rely on empirical data, often necessitates a more extensive introduction than the brief literature review introductions typically found in empirical papers. It should encompass:

Regular literature review section in an academic article or essay

In a standard 8000-word journal article, the literature review section typically spans between 750 and 1250 words. The first few sentences or the first paragraph within this section often serve as an introduction. It should encompass:

In some cases, you might include:

Introduction to a literature review chapter in thesis or dissertation

Some students choose to incorporate a brief introductory section at the beginning of each chapter, including the literature review chapter. Alternatively, others opt to seamlessly integrate the introduction into the initial sentences of the literature review itself. Both approaches are acceptable, provided that you incorporate the following elements:

Examples of literature review introductions

Example 1: an effective introduction for an academic literature review paper.

To begin, let’s delve into the introduction of an academic literature review paper. We will examine the paper “How does culture influence innovation? A systematic literature review”, which was published in 2018 in the journal Management Decision.

Example 2: An effective introduction to a literature review section in an academic paper

The second example represents a typical academic paper, encompassing not only a literature review section but also empirical data, a case study, and other elements. We will closely examine the introduction to the literature review section in the paper “The environmentalism of the subalterns: a case study of environmental activism in Eastern Kurdistan/Rojhelat”, which was published in 2021 in the journal Local Environment.

Thus, the author successfully introduces the literature review, from which point onward it dives into the main concept (‘subalternity’) of the research, and reviews the literature on socio-economic justice and environmental degradation.

Examples 3-5: Effective introductions to literature review chapters

Numerous universities offer online repositories where you can access theses and dissertations from previous years, serving as valuable sources of reference. Many of these repositories, however, may require you to log in through your university account. Nevertheless, a few open-access repositories are accessible to anyone, such as the one by the University of Manchester . It’s important to note though that copyright restrictions apply to these resources, just as they would with published papers.
