Changes are coming to the WorldCat Registry API on 1 July 2018

OCLC will transition to a new version of the WorldCat Registry API on 1 July 2018 which will require users to discontinue use of current versions, including:

• Search Retrieve URL (SRU)
• Resource Description Framework (RDF)

This change will require updates to your applications to use OCLC WSKeys and resource oriented URL patterns. The new WorldCat Registry API will continue to offer the same functionality (excluding personally identifiable information) and provide more secure access.    

To support you through this change, we have developed documentation which contains details on the new version of the WorldCat Registry API to help you make the appropriate changes.

If you have any questions in the interim, please contact Karen Coombs.
