The WorldCat Metadata API is a read-write service for WorldCat that makes it possible to add or update master bibliographic records in WorldCat, maintain holdings information, and work with local bibliographic data. In May 2020, the WorldCat Metadata API 1.1 was released to support searching WorldCat by all available indexes and retrieval of shared print information, such as retention commitments. This new version runs in parallel with the original WorldCat Metadata API.
