  As a result of the ongoing integration of the activities of OCLC and the Research Libraries Group (RLG) which began in July 2006, the migration of records from the RLG Union Catalog to OCLC’s WorldCat is now complete. The NUCMC website now provides searching access, via the NUCMC/OCLC gateway, not only to the WorldCat records that were accessible prior to the merger, but also to the RLG Union Catalog records that were previously accessible only via the NUCMC/RLG gateway. NUCMC very much appreciates the cooperation of OCLC in making this resource available to researchers.

The mission of the NUCMC program is to provide and promote bibliographic access to the nation's documentary heritage. This mission is realized by NUCMC production of cataloging describing archival and manuscript collections held by eligible repositories located throughout the United States and its territories. The program's mission is further realized by the provision of free searching, via NUCMC gateways, of archival and manuscript cataloging in OCLC WorldCat.
