Membership resources

Stay up to date on core membership information, guiding principles and governance documents, member groups, and other resources related to OCLC's Global and Regional Councils.

Becoming an OCLC member

Membership in OCLC brings many benefits to a library and its users, including global access to information, high quality research, participation in governance, and the value of shared resources. 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 as set forth in Membership Criteria annually reviewed by the Board Membership Committee. These criteria require an institution to complete at least one of these activities annually:

  • 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.

Maintain your voting contact

One of the most unique and important benefits of OCLC membership is electing member representatives to your Regional Council. Delegates elected from these councils (Americas; Asia Pacific; and Europe, the Middle East, and Africa) reflect your interests through the OCLC Global Council, which works on behalf of members worldwide. Elections take place each year, and each member institution with qualifying activity as of 30 June receives one vote.
