What is the Dewey Decimal System?

How does the dewey decimal system work, dewey decimal system classes.

• What’s included in the Dewey Decimal System printable bundle?

In libraries, fiction books can be organized in a variety of ways. Nonfiction books , though, are nearly always classified using the Dewey Decimal System. Invented in the late 1800s by Melvil Dewey, this system revolutionized the way libraries helped customers find books. Prior to Dewey’s system, libraries assigned each nonfiction book a number using their own system. Because nonfiction library stacks weren’t open to the public, only librarians needed to know how each library’s system worked.

Dewey suggested breaking books down by subject, assigning them detailed “call numbers” that showed exactly where they fit into specific categories, known as classes. This allowed patrons to find their own books more easily, using the call number assigned to each. The system has changed and expanded over time, as new subjects (such as computer science) became popular. But the overall classification system itself continues to work in the same way Dewey originally envisioned.

Learn more about Melvil Dewey here.

Each book is assigned a starting number from 000 to 999, based on its overall subject matter. Within each class, further numbers help break down categories into even more specific subjects. The three-digit number before the decimal point places the book into a broad category, while numbers after the decimal point get much more specific.

To understand it, it’s easiest to look at an example. We’ll use David McCullough’s well-known biography of U.S. president John Adams . Its basic Dewey Decimal call number is 973.4. Here’s how librarians get that number:

First, they find the three-digit number that comes before the decimal point:

• 973: United States

Then, they break the class down even further by using numbers after the decimal point.

• 973.4: Constitutional period, 1789–1809

Depending on the book, there may be even more numbers after the decimal point. There may also be other numbers assigned to help distinguish similarly titled books from one another. For a more complete look at the Dewey Decimal System chart and how it works, click here. ADVERTISEMENT

Here’s a closer look at the general categories in the Dewey Decimal System. For more details on each, visit the OCLC’s Dewey Services page here .

An essential handbook of the Dewey Decimal Classification System

CHICAGO — The Dewey Decimal Classification (DDC), used in 200,000 libraries across 140 countries, has entered a new age, primarily maintained today as a continuously revised electronic system rather than an occasionally updated set of print volumes. Its editors have added newly emerging topics and made it an increasingly faceted, semantically rich, modern system. Simultaneously, the editorial process has become democratized and more responsive to global needs. Published by Facet Publishing and available through the ALA Store, “ A Handbook of History, Theory and Practice of the Dewey Decimal Classification System ” is an indispensable guide to today’s DDC, an essential companion for DDC classifiers, and an accessible resource for students and continuing learners. Written by M. P. Satija and Alex Kyrios, this handbook’s coverage includes:

• a brief history of the system, its editors, and its development;
• specialized examinations of specific parts of the classification;
• extensive guidance on number building, with many examples;
• a WebDewey-specific chapter, covering the system's benefits and features; and
• concise summaries of primary takeaways, a glossary, and extensive bibliography.

Satija is an Emeritus fellow in the Department of Library & Information Science, Guru Nanak Dev University, India. In his long professional career he has written extensively on library classification systems, especially the Dewey Decimal Classification and the Colon Classification. He has authored textbooks on every edition of the DDC since 1979 and has collaborated with three successive editors of the DDC. Dr. Satija serves on the editorial boards of many international journals including the ISKO journal Knowledge Organization , and is a member of the UDC Consortium, The Hague.

Kyrios is the Senior Editor of the Dewey Decimal Classification at OCLC, based out of the Library of Congress. He is responsible for overseeing the continuous updating and revision of the classification, working with partners and volunteers around the world.

Facet Publishing , the commercial publishing and bookselling arm of CILIP: the Chartered Institute of Library and Information Professionals, is the leading publisher of books for library and information professionals worldwide. ALA Store purchases fund advocacy, awareness and accreditation programs for library and information professionals worldwide. ALA Editions | ALA Neal-Schuman publishes resources used by library and information professionals, scholars, students, and educators to improve programs and services, build on best practices, enhance pedagogy, share research, develop leadership, and promote advocacy.

Dewey Decimal Classification

Need more help.

If you have further questions about DDC, creating numbers, etc. please contact:

• The Dewey Program at the Library of Congress
• OCLC Dewey Resources  (you may also contact OCLC or the OCLC Community Forum for deeper questions)

What are the Numbers?

000 - 099 = General Works, Computer Science & Information 100 - 199 = Philosophy & Psychology 200 - 299 = Religion 300 - 399 = Social sciences 400 - 499 = Language 500 - 599 = Science 600 - 699 = Technology 700 - 799 = Arts & recreation 800 - 899 = Literature 900 - 999 = History & Geography

What's the 2nd Half of the Call Number?

The letters and numbers following the Dewey number in the call number are called "Cutter Numbers". They always begin with a letter, so you'll know when the Dewey number stops. Cutter numbers further identify a book and indicate the author's name. If there is no author, the title is used instead.

We use a Cutter Number table to translate an author's last name into the cutter. You can see an example of one of these tables here .

Here are some examples of author last names and their Cutter numbers:

Stark: St282

Targaryen: T174

Lannister: L283

Baratheon: B2318

What is Dewey Decimal Classification?

If you've looked up an item in Kemp Library, you'll notice that it's call number is a sequence of numbers followed by letters.  Why? By assigning call numbers, we can shelve books on similar topics together.  We use a classification system called the Dewey Decimal System to create those numbers.  

The Dewey Decimal System is also called Dewey Decimal Classification, Dewey, and DDC.

Dewey Decimal Classification was created in 1876 by Melvil Dewey.  Before the DDC was invented, libraries had items on the shelf in the order they were acquired, which could make it difficult to fine what you were looking for.  Dewey Decimal Classification provides a structure for labeling items so that they will sit with items of the same or similar topics on the shelf.

Dewey has 10 broad classifications:

• 000 - 099 = General Works, Computer Science & Information
• 100 - 199 = Philosophy & Psychology
• 200 - 299 = Religion
• 300 - 399 = Social sciences
• 400 - 499 = Language
• 500 - 599 = Science
• 600 - 699 = Technology
• 700 - 799 = Arts & recreation
• 800 - 899 = Literature
• 900 - 999 = History & Geography

Each of these classifications serves as an umbrella, with many subtopics in each area.  The longer the Dewey number, the more specific the subject is.  For instance, works on comprehensive general science would be in 500, but if you wanted to look for Biology you would look in 570.  Or if you were interested in all kinds of sports, indoor and outdoor, you would look in 790, but if you were interested in ball games you'd look in 796.3. and if you were interested in golf you'd look in 796.352.  And then there are more specific numbers that build out from the golf number if you want to get very specific.  By "build out", it means that you start with a basic number and add to it (build) to develop it's specificity.  Here you can see we went from general sports, to ball sports, to golf - and with each subject, the number grew.   Dewey numbers start in large general areas, and as the number gets longer, the more specific the subject gets.

The more numbers there are after a decimal in a call number, means that the number is highly specific.  So the call number 813 is for general works of American fiction, 813.6 is American works of fiction published after 2000, and 816.609 is for historigraphical or critiques of American fiction published in 2000 or later. 

So, when looking for a book, we recommend you also browse the shelves around that call number because you're likely to find many materials that will also interest you and be on topic.

The Dewey Decimal System: Classification Numbers

• Classification Numbers
• Reading Call Numbers
• Delgado Community College Locations

The Dewey decimal system coordinates materials on the same subject and on related subjects to make items easier to find on the shelves by using a combination of letters and numbers.

 The Dewey system has ten main classes, which are listed below.

• 000 Generalities 
• 100 Philosophy and Psychology
• 200 Religion
• 300 Social Science
• 400 Language
• 500 Natural Science and Mathematics
• 600 Technology (Applied Sciences)
• 800 Literature
• 900 Geography and History

Each of the above classes has ten divisions . These divisions are further divided--and then further divided. Each division becomes more specific. For instance, the more numbers, the more specific the subject. In this way, the Dewey classification system progresses from the general to the specific.  

The Dewey Decimal Classification (DDC) is used by most libraries to categorize its material. The call number is composed of two parts: the Dewey Decimal Classification and the Cutter Number.

Call Numbers

Once you know the call number for an item, which you determine by searching the online catalog, ISAAC, you can locate the item in the library. Call numbers serve two main functions within a library:

·         They tell you where an item is located by providing a unique "address" for every item within a library, and

·         They tell you what subject area an item is assigned to. This allows you to browse the shelves around a particular item to find other materials on the same or similar subjects.

Cutter Number

A cutter number consists of the first letter of the author’s last name and a series of numbers that allow books to be placed on the shelves alphabetically.

Cutter numbers can be used to make a distinction between books by the same author. A lowercase letter, normally the first letter of the title of the book is assigned.

About the Dewey Decimal System

Schewe Library catalogs its materials using the Dewey Decimal System (DDS), also known as Dewey Decimal Classification (DDC). The DDS is in its 23rd edition, with updates now made to its online version, WebDewey. Still, the core function of the DDS remains the same: the library assigns a classification number that unambiguously locates a particular volume in a position relative to other books in the library, on the basis of its subject. There are ten main classes, a hundred divisions, and a thousand sections, with innumerable subsections.

Dewey Decimal Classification , system for organizing the contents of a library based on the division of all knowledge into 10 groups, with each group assigned 100 numbers. The 10 main groups are: 000–099, general works; 100–199, philosophy and psychology; 200–299, religion; 300–399, social sciences; 400–499, language; 500–599, natural sciences and mathematics; 600–699, technology; 700–799, the arts; 800–899, literature and rhetoric; and 900–999, history, biography, and geography. These 10 main groups are in turn subdivided again and again to provide more specific subject groups. Within each main group the principal subseries are divided by 10; e.g., the history of Europe is placed in the 940s. Further subdivisions eventually extend into decimal numbers; e.g., the history of England is placed under 942, the history of the Stuart period at 942.06, and the history of the English Commonwealth at 942.063.

Based on W.T. Harris’ classification for the St. Louis Public Library, the Dewey system was first formulated by the American librarian Melvil Dewey in 1873 for application in the Amherst College Library. It was first published in 1876, and the 20th edition of the system had been published by the late 20th century.

The Dewey system’s numerical classification provides a shorthand identification and location tool. The notation lends itself to memory through the constant repetition of a standard pattern (area arrangement, different numbers for particular languages), through parallel subject developments (each book of the Bible given the same development as the Bible as a whole), and through patterned repetition of standard subdivisions (theory, study and teaching, history, geography, etc.). To distinguish works within a group and to expedite retrieval, many libraries add a book number created from the Cutter, or Cutter-Sanborn, Tables, which provide further specifications for author and genre .

Because an abridged as well as a full schedule (or classificatory guide) of the system has been developed, the Dewey Decimal Classification is adaptable to libraries of various sizes. The Index to the Dewey Decimal systems, a relative one (i.e., one having cross-references), arranges all topics expressed or implied, with every synonym in alphabetical order.

The names Dewey Decimal Classification and Dewey (when referring to the former) are trademarks of the OCLC Online Computer Library Center.

How to read a Dewey Decimal Number

The children collection books are marked as follows:

Dewey Decimal Classification

The classification is made up of ten main classes or categories, each divided into ten secondary classes or categories, and each further divided into ten subdivisions. This in turn can be further divided. Each division becomes more specific.

The main Dewey Decimal classes are:

          000 Generalities

          100 Philosophy and psychology

          200 Religion

          300 Social Sciences

          400 Language

          500 Natural sciences and mathematics

          600 Technology (Applied sciences)

          700 The arts (fine and decorative)

          800 Literature and rhetoric

          900 Geography and history

Cutter Numbers are added to the classification system, because it is possible for many books to be classified with the same Dewey classification number. The cutter number gives each book a unique number that serves as the address of the book. They usually consist of the first letter of the author’s last name and series of numbers. And if the library has several books by the same author a “work letter” is used, usually the first letter of the title of the book.
