Collection Management API transition resources 

Support for the Collection Management API will end 1 April 2026. OCLC recommends customers begin transitioning to the Worldcat Metadata API as soon as possible. The WorldCat Metadata API is much more modern, flexible, and robust.

We acknowledge that a common use case for the WMS Collection Management API has been a spine label printing solution. This feature is supported natively in Record Manager, WMS Circulation or WMS Acquisitions.

About WorldCat Metadata API

• Modern authentication technology patterns of OAuth 2.0 to support different types of client applications. 
• Support for reading and writing bibliographic, local bibliographic, and local holdings data
• Additional search options and indexes for precise searching. 

Recommended transition paths 

We encourage you to implement alternate OCLC solutions for your primary uses of the Collection Management API.
