OCLC is a worldwide library cooperative, owned, governed and sustained by members since 1967. We connect libraries to manage and share the world’s knowledge and to form a community dedicated to the values of librarianship: cooperation, resource sharing and public service.
Our public purpose is a statement of commitment to each other—that we will work together to improve access to the information held in libraries around the globe, and find ways to reduce costs for libraries through collaboration. OCLC members cooperatively produce and maintain WorldCat—the world’s most comprehensive database of library materials and a tribute to collaborative spirit of libraries. 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 regional councils of member libraries.
