Abstract

In this paper, I will present a general introduction to Edition 21, the new edition of the Dewey Decimal Classification. I will also briefly describe the underlying database and some new uses of Dewey in the electronic information environment. The twenty-first edition of the Dewey Decimal Classification has just been published in print and electronic versions. Edition 21 contains changes in the organization of several disciplines. It also provides expansions for new areas of knowledge, accommodates many political and social changes, and includes updated terminology. Edition 21 also features several structural changes that make the Classification easier to apply, reflect modern classification design principles, and support electronic distribution.
