Get your holdings in WorldCat.org

When you participate in the OCLC cooperative by contributing metadata and subscribing to WorldCat® Discovery, your library's records will appear in WorldCat.org search results at no additional cost. To get started, contribute local holdings information and other metadata via one or more of the following OCLC services:

  • Connexion®,
  • CatExpress®,
  • Contract Cataloging™,
  • Batchload,
  • WorldCat Cataloging Partners,
  • CONTENTdm®, or
  • WorldCat Digital Collection Gateway.

(Note: many of these services require an annual subscription or may have other costs associated with them.)

Then, subscribe to WorldCat Discovery.

Europe, the Middle East, and Africa

Libraries in Europe, the Middle East, or Africa can purchase a subscription to WorldCat.org, which includes regular updates through a batchload process. Contact your local OCLC Library Services Consultant for more information.
