All libraries with OCLC Cataloging and Metadata Subscriptions may contribute new WorldCat records, edit existing master records and export records into local systems. Libraries with advanced authorization levels may make additional enhancements to WorldCat records.
Any member library with an OCLC Cataloging and Metadata Subscription or additional authorizations may participate in the Expert Community, which embodies the library values of cooperation, resource sharing and public service. As an evolution of the Enhance program, this group distributes the work of maintaining WorldCat by making real-time corrections and enrichments to WorldCat master records. As more libraries participate in the Expert Community to improve master records, WorldCat becomes more valuable to all libraries and library users.
National Level Enhance Program
Libraries with membership in the Program for Cooperative Cataloging, or PCC, can modify certain elements in PCC records that are not available for other libraries to edit in WorldCat. These libraries receive National Level Enhance authorization to replace and lock master records.
PCC consists of
- Monographic Bibliographic Record Cooperative Program (BIBCO),
- Cooperative Online Serials Program (CONSER),
- Name Authority Cooperative Program (NACO), and
- Subject Authority Cooperative Program (SACO).
All of these groups contribute specific records and improvements to WorldCat. Further, CONSER participants can create and edit authenticated CONSER serial records.
National Level Enhance authorization also allows libraries to add records to and edit records in the LC Authority File.
U.S. Newspaper Program
In addition, the United States Newspaper Program (USNP) enhances the quantity and quality of newspaper records in WorldCat.
