About Dewey and OCLC Forest Press

The Dewey Decimal Classification system (DDC) is a general knowledge organization tool that is continuously revised to keep pace with knowledge. The system was conceived by Melvil Dewey in 1873 and first published in 1876. The DDC is published by Forest Press, which in 1988 became a division of OCLC Online Computer Library Center, Inc.

The Dewey Decimal Classification is the most widely used library classification system in the world. It is used in more than 135 countries and has been translated into over 30 languages. Recent translations in progress or completed include Arabic, Chinese, French, Greek, Hebrew, Italian, Persian, Russian, Spanish, and Turkish. In the United States, 95% of all public and school libraries, 25% of all college and university libraries, and 20% of special libraries use the DDC. In addition, Dewey is used for other purposes, e.g., as a browsing mechanism for resources on the World Wide Web.
