A Brief Introduction to the
Dewey Decimal Classification
History and Current Use
The Dewey Decimal Classification (DDC) system is a general knowledge
organization tool that is continuously revised to keep pace with knowledge. The
system was conceived by Melvil Dewey in 1873 and first published in 1876. The
DDC is published by OCLC Online Computer Library Center, Inc. OCLC owns all
copyright rights in the Dewey Decimal Classification, and licenses the system for a
variety of uses.
The DDC is the most widely used classification system in the world. Libraries in
more than 135 countries use the DDC to organize and provide access to their
collections, and DDC numbers are featured in the national bibliographies of more
than 60 countries. Libraries of every type apply Dewey numbers on a daily basis
and share these numbers through a variety of means (including WorldCat, the
OCLC Online Union Catalog). Dewey is also used for other purposes, e.g., as a
browsing mechanism for resources on the web.
The DDC has been translated into over thirty languages. Translations of the
latest full and abridged editions of the DDC are completed, planned, or underway in
Arabic, Chinese, French, German, Greek, Hebrew, Icelandic, Italian, Korean,
Norwegian, Russian, Spanish, and Vietnamese.
Development
One of Dewey’s great strengths is that the system is developed and maintained
in a national bibliographic agency, the Library of Congress. The Dewey editorial office
is located in the Decimal Classification Division of the Library of Congress, where
classification specialists annually assign over 110,000 DDC numbers to records for
works cataloged by the Library. Having the editorial office within the Decimal
Classification Division enables the editors to detect trends in the literature that must
be incorporated into the Classification. The editors prepare proposed schedule
revisions and expansions, and forward the proposals to the Decimal Classification
Editorial Policy Committee (EPC) for review and recommended action.
EPC is a ten-member international board whose main function is to advise the
editors and OCLC on matters relating to changes, innovations, and the general
development of the Classification. EPC represents the interests of DDC users; its
members come from national, public, special, and academic libraries, and from
library schools.
Editions
The DDC is published in full and abridged editions in print and electronic
versions. The abridged edition is a logical truncation of the notational and structural
hierarchy of the corresponding full edition on which it is based, and is intended for
general collections of 20,000 titles or less. WebDewey and Abridged WebDewey, the
electronic versions of the full and abridged editions, respectively, are updated
frequently and contain additional index entries and mapped vocabulary. The
electronic versions and supplemental web postings are the chief sources of ongoing
updates to the DDC. On the Dewey web site (www.oclc.org/dewey), selected new
1
Brief Introduction to the DDC
numbers and changes to the DDC are posted monthly, and mappings between
selected new Library of Congress Subject Headings (LCSH) and Dewey numbers
are posted biweekly.
Structure and Notation
The DDC is built on sound principles that make it ideal as a general knowledge
organization tool: meaningful notation in universally recognized Arabic numerals,
well-defined categories, well-developed hierarchies, and a rich network of
relationships among topics. In the DDC, basic classes are organized by disciplines
or fields of study. At the broadest level, the DDC is divided into ten main classes,
which together cover the entire world of knowledge. Each main class is further
divided into ten divisions, and each division into ten sections (not all the numbers
for the divisions and sections have been used). The main structure of the DDC is
presented in the DDC Summaries following this introduction. The headings
associated with the numbers in the summaries have been edited for browsing
purposes, and do not necessarily match the complete headings found in the
schedules.
The first summary contains the ten main classes. The first digit in each
three-digit number represents the main class. For example, 600 represents
technology.
The second summary contains the hundred divisions. The second digit in
each three-digit number indicates the division. For example, 600 is used for
general works on technology, 610 for medicine and health, 620 for engineering,
630 for agriculture.
The third summary contains the thousand sections. The third digit in each
three-digit number indicates the section. Thus, 610 is used for general works on
medicine and health, 611 for human anatomy, 612 for human physiology, 613 for
personal health and safety.
Arabic numerals are used to represent each class in the DDC. A decimal point
follows the third digit in a class number, after which division by ten continues to the
specific degree of classification needed.
A subject may appear in more than one discipline. For example, “clothing” has
aspects that fall under several disciplines. The psychological influence of clothing
belongs in 155.95 as part of the discipline of psychology; customs associated with
clothing belong in 391 as part of the discipline of customs; and clothing in the sense
of fashion design belongs in 746.92 as part of the discipline of the arts.
Hierarchy
Hierarchy in the DDC is expressed through structure and notation. Structural
hierarchy means that all topics (aside from the ten main classes) are part of all the
broader topics above them. Any note regarding the nature of a class holds true for
all the subordinate classes, including logically subordinate topics classed at
coordinate numbers.
Notational hierarchy is expressed by length of notation. Numbers at any given
level are usually subordinate to a class whose notation is one digit shorter;
coordinate with a class whose notation has the same number of significant digits;
2
Brief Introduction to the DDC
and superordinate to a class with numbers one or more digits longer. The
underlined digits in the following example demonstrate this notational hierarchy:
600
Technology
630
Agriculture and related technologies
636
Animal husbandry
636.7
Dogs
636.8
Cats
“Dogs” and “Cats” are more specific than (i.e., are subordinate to) “Animal
husbandry”; they are equally specific as (i.e., are coordinate with) each other; and
“Animal husbandry” is less specific than (i.e., is superordinate to) “Dogs” and “Cats.”
Sometimes, other devices must be used to express the hierarchy when it is not
possible or desirable to do so through the notation. Special headings, notes, and
entries indicate relationships among topics that violate notational hierarchy.
Arrangement of the DDC
The print version of the latest full edition of the DDC, Edition 22, is composed of
the following major parts in four volumes:
Volume 1
(A) New Features in Edition 22: A brief explanation of the special features and
changes in DDC 22
(B) Introduction: A description of the DDC and how to use it
(C) Glossary: Short definitions of terms used in the DDC
(D) Index to the Introduction and Glossary
(E) Manual: A guide to the use of the DDC that is made up primarily of extended
discussions of problem areas in the application of the DDC. Information in the
Manual is arranged by the numbers in the tables and schedules
(F) Tables: Six numbered tables of notation that can be added to class numbers to
provide greater specificity
(G) Lists that compare Editions 21 and 22: Relocations and Discontinuations;
Reused Numbers
Volume 2
(H) DDC Summaries: The top three levels of the DDC
( I) Schedules: The organization of knowledge from 000–599
3
Brief Introduction to the DDC
Volume 3
(J) Schedules: The organization of knowledge from 600–999
Volume 4
(K) Relative Index: An alphabetical list of subjects with the disciplines in which they
are treated subarranged alphabetically under each entry
Entries
Entries in the schedules and tables are composed of a DDC number in the
number column (the column at the left margin), a heading describing the class that
the number represents, and often one or more notes. All entries (numbers,
headings, and notes) should be read in the context of the hierarchy.
In the print version of the DDC, the first three digits of schedule numbers (main
classes, divisions, sections) appear only once in the number column, when first
used. They are repeated at the top of each page where their subdivisions continue.
Subordinate numbers appear in the number column, beginning with a decimal
point, with the initial three digits understood.
Some numbers in the schedules and tables are enclosed in parentheses or
square brackets. Numbers and notes in parentheses provide options to standard
practice. Numbers in square brackets represent topics that have been relocated or
discontinued, or are unassigned. Square brackets are also used for standard
subdivision concepts that are represented in another location. Numbers in square
brackets are never used.
Number Building
Only a fraction of potential DDC numbers are included in the schedules. It is
often necessary to build or synthesize a number that is not specifically listed in the
schedules. Such built numbers allow for greater depth of content analysis. There
are four sources of notation for building numbers: (A) Table 1 Standard
Subdivisions; (B) Tables 2–6; (C) other parts of the schedules; and (D) add tables
in the schedules.
Number building is initiated only upon instructions in the schedules (except
for the addition of standard subdivisions, which may take place anywhere unless
there is an instruction to the contrary). Number building begins with a base
number (always stated in the instruction note) to which another number is added.
