# DEWEY DECIMAL SYSTEM

A numerical classification system of books employed by libraries.

The Dewey Decimal System, created by Melvil Dewey, is a reference system that classifies all subjects by number. The numbers in a particular grouping all refer to a designated general topic. For example, the numbers in the 340s concern topics of law. Each new number after the decimal point further subdivides the previous number and the subject it covers.
