The Caveman’s Guide to the
Dewey Decimal System
The Story of the Numbers Used for Nonfiction Books
In 1873 Mr. Melvil Dewey devised a system for classifying books which is used in many libraries.
He chose certain main subjects and numbers, so that all nonfiction books on the same subjectwould be together on the shelf.
The Dewey Decimal System
The system groups books by topic by dividing them into 10 basic categories.
