The WorldCat Metadata API is available to employees of qualifying institutions at no additional charge for non-commercial use. Qualifying institutions are OCLC member libraries that contribute to WorldCat and are visible on WorldCat.org*.
(*) Contribution to WorldCat is here defined as maintaining an OCLC cataloging subscription or another agreement to provide a full representation of the library's currently cataloged bibliographic records. Libraries that catalogue in the Dutch GGC (Gemeenschappelijk Catalogiseersysteem) or in the CBS systems of CBS partner organisations also meet the cataloging qualification, if there is also a partnership agreement in place with OCLC. Visibility on WorldCat.org is determined by having a subscription to WorldCat on FirstSearch or other type of WorldCat.org agreement.
The OCLC Developer Network supports the use of OCLC Web Services—a set of tools and APIs that expose data and services for WorldCat and our member libraries and partner institutions or companies. learn more »
