Developer-level Access to WorldCat - for bibliographic holdings and location data

  • Status: Production
  • Sandbox access: Yes

WorldCat Search API 2.0 initial release available

The WorldCat Search API 2.0 supports much of the core functionality of the original WorldCat Search API in a streamlined JSON format. The API also allows enhanced access to local holdings record data across the cooperative, including shared print retention information.

As functionality is added to this version of the API, OCLC will announce sunset plans for the original version.

Who can use it
