How To Use the Dewey Decimal System

The Dewey Decimal System organizes information into 10 broad areas, which are broken into smaller and smaller topics. Different topics are assigned numbers, known as "call numbers." For example, "Tigers" are given the number 599.756. To see what books the library currently has in on tigers, go to the nonfiction shelves and find the books that have that number on their spine label. A list of some of the information you can find in the different Dewey Decimal areas appears below. Use the Library's Catalog to search for specific subjects.
