How do member libraries delete holdings via Z39.50?

Applies to

• Z39.50 

Answer

OCLC supports deleting institution holding symbols via the Z39.50-1995 DatabaseUpdate Extended Service Definition. For more information, see Database update implementation for OCLC Z39.50 Cataloging: Extended Service Definition.

 Note:

• All local holdings records (LHRs) associated with a bibliographic record are deleted when holdings are deleted from the bibliographic record. To retain LHRs, move them to another record before deleting holdings from a bibliographic record.
• Holdings deleted via the Z39.50-1995 DatabaseUpdate Extended Service Definition do not appear in the OCLC Usage Statistics Portal.
