Integration of the RLG Union Catalog into WorldCat

During the first six months of 2007, RLG services are being combined with OCLC's to support record creation, record supply, and cataloging. As this transition progresses, please refer to the RLG Transition Information page at for links to current objectives, ongoing processes, and updated targets for completion.

Integrating RLG bibliographic records into WorldCat is scheduled as follows.

Phase 1: Match all RLG Union Catalog Primary Cluster Members (representing the most complete cataloging in a cluster) against WorldCat, adding new Master Records for titles not yet represented but without holdings. Enhance existing Master Records from matched records as appropriate (e.g., add original scripts to romanized-only Master Records).
Target for completion: March 31, 2007
Status as of February 28, 2007: OCLC RLG Service Center has sent all 53 million Primary Cluster Member records for matching.
Processed: 43.5 million records
Matched: 36.3 million records
New Master Records created: 7.1 million records (16% add rate)
Phase 1A: OCLC RLG Service Center sends another set of Primary Cluster Members that were added or updated since the first set of records were extracted from the RLG Union Catalog in December 2006.
Phase 2: Load Institution Records from the RLG Union Catalog intoWorldCat for the institutions that requested that the OCLC RLG Service Center extract their records for them. Add Institution Records and postings for records that match; create new Master Records, postings, and Institution Records linked to the new Master Record for titles not yet represented. (Institution records will not be visible to users until the Connexion 2.0 release.)
Targeted start: March 2007
Phase 2A: Load Institution Records that were created, edited, or batch loaded in the RLG Union Catalog since the first set of Institution Records were extracted from the RLG Union Catalog.
Targeted start: June 2007
Phase 3: Load records from RLG Union Catalog Contributors' local systems. Add Institution Records and postings for records that match; create new Master Records, postings, and Institution Records linked to the new Master Record for titles not yet represented.

Targeted start: June 2007
