DDC 22 offers many updates to Dewey users worldwide

摘要

In September 2003, OCLC will publish Dewey Decimal Classification, Edition 22 (DDC 22), the new full edition of the Dewey Decimal Classification. WebDewey subscribers have had access to the electronic version of the new edition since mid-June 2003. DDC 22 contains several major updates, many new numbers and topics, and a few structural changes. There is one important difference between DDC 22 and other recent editions: DDC 22 contains no complete or extensive revisions. In other words, several new developments have been added and many classes have been revised and expanded, but no schedule has been changed so fundamentally that a complete reordering has resulted--good news for Dewey users! Here's a detailed look at what Dewey users around the worldwill find in the new edition.
