About OCLC

The world’s libraries. Connected.

Connecting people to knowledge through library cooperation.

Record by record, keystroke by keystroke, librarians built OCLC into the world’s largest library cooperative. We are dedicated to the public purposes of furthering access to the world’s information and reducing the rate of rise of library costs.


OCLC connects libraries in a global network to manage and share the world’s knowledge and to form a community dedicated to the values of librarianship: cooperation, resource sharing and universal access. The network links members to a powerful, cloud-based infrastructure that provides the systemwide intelligence and cooperative platform needed to collectively innovate and drive operational efficiencies in metadata creation, interlibrary loan, digitization, discovery and delivery. It also provides opportunities for cooperation and resource sharing built around a worldwide community of users—working together at the scale of the Web.

The OCLC cooperative is member-owned and member-governed. Librarians guide and shape our direction through a 16-member Board of Trustees—more than half of whom are librarians—and a global council of librarians, who are elected by librarians from regional councils of member libraries.

“It’s very gratifying to be involved in an organization that’s at the forefront of the technological change that’s shaping libraries. OCLC is doing things that affect libraries across the world and making libraries better places for our users.”
