How to become a member

Join the OCLC cooperative

The core tenet of membership in the OCLC cooperative is contribution and sharing of resources. Primarily, this happens when your institution contributes its holdings to WorldCat, the world's largest online network of library content. Many roads lead to WorldCat—whether you contribute holdings as an independent institution or as a member of a consortium, state or national library—as long as your institution's holdings are updated at least one time within a three-year period, your institution will maintain its membership status.

There is no separate membership fee to join OCLC. However, a subscription to WorldCat or other services that contribute intellectual content are required. Other possible collaborative contributions that qualify for membership include contributing to the QuestionPoint knowledge base and borrowing or lending resources through The WorldCat Resource Sharing service on OCLC's global resource sharing network.
