Dewey Decimal System

Back to How to Find Books in the Library

A Dewey “Decimal” number always has three digits to the left of the decimal, There are ten major subject categories that correspond to the first digit to the left of the decimal or the Hundreds. The second digit corresponds to the sub categories (Tens) and third digit corresponds to the sub sub categories. After that, you go to digits to the right of the decimal: the more digits, the more specific the classification. There can be any number of numbers to the right of the decimal.

Listed below are the Hundreds. If you click on any category, you can see a list of the Tens associated with it and under each Ten are the sub sub categories.
