Stay current with ongoing updates to the DDC
The Dewey Decimal Classification (DDC) system is updated on an ongoing basis. Check the Dewey Web site regularly for the resources you'll need to keep your collections organized and current. These resources include LCSH/DDC numbers of interest, which suggest how classifiers can treat materials in topics that were introduced after the current print edition of the DDC was published.
All libraries face myriad challenges in classifying their library materials. The Dewey editors seek the advice of Dewey users on ways to improve treatment of specific subject areas in occasional Discussion papers with instructions for returning comments. Subscribe to 025.431: The Dewey blog for ongoing advice on the use of the DDC.
Your subscription to WebDewey or Abridged WebDewey includes regular updates that keep your cataloging and classification efforts aligned with the latest updates to the Dewey Decimal Classification (DDC) system. Both services contain the latest versions of the schedules, tables, Manual and Relative Index entries (print and electronic) from the respective enhanced DDC databases. The hierarchical displays in WebDewey and Abridged WebDewey feature updated main class and division captions (e.g., 700 Arts & recreation; 790 Sports, games & entertainment).
