Dewey Decimal System (DDS)

• Books in the library are arranged on the shelves according to the Dewey Decimal Classification System (developed by Melville Dewey). This system, the most commonly used in school and public libraries, divides knowledge into ten different broad subject areas, called classes, numbered 000 - 999.

Dewey Decimal System (DDS)…

• The ten main classes are divided up into smaller classes by several sets of subclasses.

• Smaller divisions (to subdivide the topic even further) are created by expanding each subclass and adding decimals if necessary.

DDC in a library

• Before a book is placed in a library it is:• Classified according to the subject matter it

covers (given the Dewey number). • Three letters are added to this number. This

represents the author's last name or the first word of the title (if the book is edited with no one author).

• The number indicates where the book will be shelved in the library.

Finding Books on the Shelves Using the Dewey System:

• Following are call numbers arranged in the order that they would sit on the shelves:

636.04 , 636.3 , 636.450 Books are arranged by the lowest to the highest

number and the first to the last letter.(A –Z)
