Join other libraries in advancing librarianship

OCLC membership gives you access to the global resources that are supported by the 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.

Libraries may also belong to a group that engages with OCLC on their behalf that would qualify them for OCLC membership. 

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:
