Do The Dewey!

Books in public libraries are arranged on the shelves using the Dewey Decimal Classification system, a numerical system that organizes nonfiction by subject. 

Each nonfiction book is assigned a "call number."   The call number groups books together by subject which keeps them organized.

Here is a list of the ten main Dewey subjects:

• 000 – Computer science, Library and Information science & general work

• 100 – Philosophy and psychology

• 200 – Religion

• 300 – Social sciences

• 400 – Language

• 500 – Science

• 600 – Technology

• 700 – Arts

• 800 – Literature

• 900 – History, geography & biography
