Dewey Decimal System
Invented in 1876 by Melvil Dewey, the Dewey Decimal System (DDS) organizes knowledge into 10 broad categories or classes. Each class is then broken into 10 divisions, and each division can be divided into 10 sections. Each subject is assigned a number - a "call number"

Our library, like most school libraries, uses the Dewey Decimal System (DDS) to organize our non-fiction books, and uses E for Easy Picturebooks, FIC for Fiction Chapter Books, and B for Biographies rather than use Mr. Dewey's actual numbers for these types of books.
