Members meeting

Become a member

Join other libraries in advancing librarianship

OCLC membership gives you access to the resources that are supported by the global cooperative. OCLC was founded on the principle that by sharing intellectual property, libraries could better meet their objective of making the world's knowledge more accessible. Through membership, libraries contribute to the cooperative and benefit from the services, research, advocacy, and advancement programs uniquely available to members of a cooperative.

Becoming an OCLC member

Becoming an OCLC member requires action. Many institutions maintain membership by contributing holdings to WorldCat as a single institution, as a member of a consortium, or through a state or national library.

While there is no separate membership fee, OCLC members contractually agree to participate in cooperative services. Part of maintaining membership in the cooperative also includes completing at least one of these activities annually:

  • Contributing metadata
  • Sharing holdings information
  • Making digital content available to other members through WorldCat Digital Collection Gateway
  • Sharing materials using OCLC services, such as WorldShare Interlibrary Loan, ILLiad or other services
  • Subscribing or contracting for an OCLC library management system that will facilitate global sharing when transitioned to WorldShare.
