Request Types
The WorldCat Registry has three different types of requests
- Search - Allows developers to search the Registry using an SRU service with a variety of indexes
- Details - Allows developers to link to an individual Registry record either by Registry ID or OCLC Symbol
- OpenURL Lookup - Allows developers to lookup the OpenURL resolver associated with a given IP address
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 »
