This is a copy of the handout that goes along with the library skills lesson on the arrangement of fiction and nonfiction materials and the Dewey Decimal Classification System.



Dewey Decimal Classification System

The Dewey decimal system is used in more than 200,000 libraries throughout the world and it has been translated into 35 languages. The Dewey decimal system, using numbers and letters, coordinates materials on the same subject and on related subjects to make items easier to find on the shelves.. All knowledge is divided into ten main classes, which are listed below

More info about the DDC

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


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