z39.50 Cataloging at a glance

Z39.50 Cataloging enables you to use your local Z39.50-compliant interface for staff access. The OCLC Z39.50 Cataloging service helps streamline cataloging workflow, reduce staff training, and decrease costs.


  • Increase local cataloging efficiency and better integrate workflow through the use of your local library system interface
  • Add efficiencies to the cataloging workflow; efficiently add holdings information to WorldCat (if the OCLC Extended Services Definition is implemented)
  • Improve staff training time—learn only one set of search indexes and procedures
  • Make cost-effective use of your Z39.50 client investment


  • Search and retrieve OCLC-MARC records in WorldCat for cataloging
  • Search and retrieve LC Names and Subjects authority file records
  • Edit records in your local system
  • Set holdings information on WorldCat online via Z39.50, or through OCLC batch services
  • Customized local displays defined by your local Z39.50 client
  • Bibliographic records include non-Latin scripts


  • You need Z39.50 client software that is:
    • Integrated or compatible with your local online system
    • Capable of implementing the OCLC Extended Services Definition of Version 3 (Z39.50-1995) for setting holdings or for requesting cataloging cards. (This capability is not required if you return holdings via batch services or EDX).

      Note: Consult with your local system vendor and/or system administrator for information on implementation of the OCLC Extended Services Definition and assistance with local client configuration.

  • Also required is the ability to extract OCLC-derived Z39.50 records from your local system (for libraries setting holdings via batch services or EDX only).
