The Manual offers advice on classifying in difficult areas, and explains how to choose between related numbers. Classification may be used to organize knowledge represented in any form, e. In the Dewey Decimal Classification, the notation is expressed in Arabic numerals.

The notation gives both the unique meaning of the class and its relation to other classes. The notation provides a universal language to identify the class and related classes, regardless of the fact that different words or languages may be used to describe the class. The system is further extended through number building, interoperable translations, association with categorized content, and mappings to other subject schemes. 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, titles or less.

Libraries in more than countries use the DDC to organize and provide access to their collections, and DDC numbers are featured in the national bibliographies of more than sixty countries. Libraries of every type apply Dewey numbers on a daily basis and share these numbers through a variety of means including WorldCat. Dewey is also used in a variety of applications on the web in support of categorization, browsing, and retrieval.

The Dewey editorial office is located in the Dewey Section of the Library of Congress, where classification specialists annually assign over 60, DDC numbers to records for works cataloged by the Library. Having the editorial office within the Dewey Section 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 represents the interests of DDC users; its members come from national, public, special, and academic libraries, and from library schools.

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 first summary contains the ten main classes. The second summary contains the hundred divisions. The third summary contains the thousand sections. 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.

This class is also used for certain specialized disciplines that deal with knowledge and information, e. Each of the other main classes — comprises a major discipline or group of related disciplines. Class includes sociology, anthropology, statistics, political science, economics, law, public administration, social problems and services, education, commerce, communications, transportation, and customs.

Literature, which is arranged by language, is found in Recreation, including sports and games, is also classed in Folk literature is classed with customs in A history of a specific subject is classed with the subject. For example, "clothing" has aspects that fall under several disciplines.

The psychological influence of clothing belongs in Notation 4. The first digit in each three-digit number represents the main class. For example, represents science.

The second digit in each three-digit number indicates the division. For example, is used for general works on the sciences, for mathematics, for astronomy, for physics. The third digit in each three-digit number indicates the section.

Thus, is used for general works on physics, for classical mechanics, for fluid mechanics, for gas mechanics. The DDC uses the convention that no number should have fewer than three digits; zeros are used to fill out numbers. A number should never end in a 0 anywhere to the right of the decimal point. Principle of Hierarchy 4. The corollary is also true: whatever is true of the whole is true of the parts. This important concept is called hierarchical force.

Certain notes regarding the nature of a class hold true for all the subordinate classes, including logically subordinate topics classed at coordinate numbers. For a discussion of notes with hierarchical force, see paragraphs 7. Because of the principle of hierarchical force, hierarchical notes are usually given only once—at the highest level of application. For example, the scope note at applies to , to , and to The words "Description, critical appraisal.

In order to understand the structural hierarchy, the classifier must read up and down the schedules and remember to turn the page. 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; and superordinate to a class with numbers one or more digits longer.

The underlined digits in the following example demonstrate this notational hierarchy: Technology Applied sciences Agriculture and related technologies Animal husbandry A see reference leads the classifier to subdivisions of a subject located outside the notational hierarchy.

A centered entry so called because its numbers, heading, and notes appear in the center of the page constitutes a major departure from notational hierarchy. A centered entry is used to indicate and relate structurally a span of numbers that together form a single concept for which there is no specific hierarchical notation available. Classifying with the DDC 5. For a discussion of approach or form, see paragraph 8. Determining the Subject of a Work 5.

Provides a comprehensive chronology of the DDC from its inception in , to the present day Describes the governance, revision machinery and updating process Gives a table of all editors of the DDC. This combined text and workbook covers the theories and principles of DDC's 23rd edition and then offers immediate practice in putting the information to use. Plentiful, clear explanations, examples and practice exercises illustrate every aspect of DDC and help students master creating DDC numbers.

Presents the text of the Dewey Decimal Classification system, a general knowledge organization tool; featuring an explanation of the special features and changes in the 21st edition, a description of the system, a glossary, tables of notation, and comparative lists. This revision of the first edition, published in , includes updated text; examples and exercises that correspond with the latest print schedules and tables; a new chapter on Classification Web; a glossary that defines technical terms in simple language; and an index.

Both professionals and paraprofessionals can brush up their classification skills. The authors offer a lesson-by-lesson approach with exercises to practice and test your skills. They cover the structure of the LC classification system, how to build a call number, classification tables, the electronic version of the schedules and shelving. American Libraries review of the first edition Recommended for professionals and paraprofessionals seeking professional development, students wanting to supplement their courses with practical applications, and library schools offering distance learning courses in cataloging.

Libraries of every type apply Dewey numbers on a daily basis and share these numbers through a variety of means including WorldCat.

Dewey is also used in a variety of applications on the web in support of categorization, browsing, and retrieval. The DDC has been translated into over thirty languages.

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 Dewey Section of the Library of Congress, where classification specialists annually assign over 60, DDC numbers to records for works cataloged by the Library. Having the editorial office within the Dewey Section 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 3 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.
