Understanding Dewey

The Dewey Decimal system categorizes NONFICTION books by 10 broad subject areas.

  • All Whitaker Library's nonfiction books are given a number starting with a MINIMUM of 3-digits. Example: 940.
  • The numbers that come after the first three help to identify specific topics within that main subject.
  • Subjects can usually be found in the same general area. Example: History of Europe 940, History of Asia 950.
