    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.

    Abstract
    The Dewey Decimal Classification is preparing for the future in a number of ways. Editorial work is supported by a UNIX-based system and access to online bibliographic databases. Two editions of Electronic Dewey have been published and a Windows version is under development The Classification is continuously revised to keep pace with knowledge. Various changes have been introduced to address classifier convenience, modern classification design principles, and electronic distribution. A Dewey research agenda has been identified to guide future development and explore new opportunities. I will describe a few of the changes underway and suggest some questions to guide future directions for the Dewey Decimal Classification.
