Web Dewey (Online DDC)

About Web Dewey

Users of DDC who started with the print version and later moved onto the Electronic version had long been requesting for more frequent institutional update of the Dewey database, hypertext linking and many other enhancements that are most effectively delivered in a browser-based setting. Apart from this, there is a very strong general trend from CDS to the Web today. Hence, Web-based access to an enhanced version of the DDC database is available through what is known as Web Dewey. The key features of Web Dewey include:

1. An easy to use, browser based interface that allows you to search the DDC (and related terminology) efficiently and navigate intuitively.
2. Thousands of Relative Index terms and built numbers not available in the print DDC.
3. Library of Congress Subject Headings (LCSH) that have been intellectually mapped to Dewey headings by DDC editors.
4. Selected LCSH mappings from the new OCLC Forest Press publication, People, Places & Things.
5. LCSH that have been statistically mapped to Dewey numbers from records in the World Cat (the OCLC Online Union Catalog).
6. Links from mapped LCSH to the LCSH authority records.
7. Quarterly updates, incorporating the latest changes to the Classification and new LCSH mappings, index terms and built numbers.
8. An annotation capability, which allows you to add your own notes into Web Deweyto reflect local classification practices.

The Web Dewey database includes the most current version of the DDC (DDC 23 and all updates since its publication in 2003), plus supplemental data. It is updated quarterly and mainly contains records for Dewey entry numbers from the schedules and tables, records for entries in the DDC manual, the DDC Relative Index and Library of Congress Subject Headings (LCSH) associated with Dewey class numbers.

The Web Dewey is available through the Dewey Services option of the OCLC connection service. There are two basic options: the user can search or browse for a subject or class number or can simply move to the Dewey schedule or tables, from the search of the browse screen, and follow the hierarchy of the classes.
