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. This service allows libraries to write MARCXML bibliographic records to WorldCat, either as new records or updated records that are replacing existing records. Existing WorldCat bibliographic records can be accessed with search and read operations. The API enables an institution to set and delete its holdings on WorldCat bibliographic records, and retrieve its own local holdings records as well as retained local holdings records.
