WorldCat® knowledge base

Making your electronic content easier to find, use and manage

The WorldCat knowledge base combines data about your library's electronic resources and linking features, enabling fast, reliable access while helping you better manage workflows associated with these materials. As of March 2014, the WorldCat knowledge base provides access to 11,266 content collections from 5,720 providers.

Unlike data in a traditional knowledge base, WorldCat knowledge base data is not tied to a particular application. Knowledge base data is added and maintained in a single place for use with a growing number of OCLC and non-OCLC services.

The WorldCat knowledge base currently enables the following functionality in OCLC services:

WorldCat knowledge base functionality is included in your OCLC Cataloging subscription and a knowledge base API is available to help members create their own unique solutions.

If you do not currently have a cataloging subscription, please contact libservices@oclc.org for more information.

For help with your WorldCat knowledge base implementation, contact  your nearest OCLC office or regional distributor.

The world's first cooperatively managed knowledge base

Several users have requested the ability to contribute data and changes to global knowledge base collections and we've listened. As a cooperative with a long-standing tradition of relying on the expert community for cataloging, we believe that making the knowledge base cooperatively managed is a positive future direction and one that will help create efficiencies for everyone in the community while improving data quality for all.  

To that end, we are introducing "cooperative data management" of the WorldCat knowledge base in three phases over the coming months. 

Rest assured that OCLC and the knowledge base team will continue to maintain knowledge base data as we always have, but with this change, we are adding the ability for our community to work with us to improve the quality of the WorldCat knowledge base. 

Give us your feedback

We encourage you to discuss the features and functions of the knowledge base including cooperative management in our discussion forum (existing kb users only) or feel free to send your comments to support@oclc.org.
We welcome any suggestions for improving or enhancing the WorldCat knowledge base for greater utility by our community in future releases. 

We are a worldwide library cooperative, owned, governed and sustained by members since 1967. Our public purpose is a statement of commitment to each other—that we will work together to improve access to the information held in libraries around the globe, and find ways to reduce costs for libraries through collaboration.
