Dewey Decimal Classification
Book sorting system
The Dewey Decimal Classification is a library cataloging system that organizes books and other materials into ten main subject classes, each subdivided by decimal numbers for increasingly specific topics.
Developed in the 1870s and still widely used, it allows patrons to locate materials by number: The cookbooks are in the 641s.
Often shortened to Dewey Decimal or just Dewey.
