OCLC is a nonprofit global library cooperative that provides shared technology services, original research, and community programs to connect libraries and make knowledge accessible worldwide. Founded in 1967 as the Ohio College Library Center, OCLC has grown into a global organization serving more than 54,000 libraries across six continents. The organization powers WorldCat, the world's most comprehensive database of library collections, enabling libraries to share data, streamline workflows, and connect people to the information held in the world's libraries.
OCLC's technology solutions include WorldShare Management Services (WMS), WorldShare Interlibrary Loan, Connexion cataloging tools, WorldCat Discovery Services, and FirstSearch. Through OCLC Research, the organization produces knowledge, evidence, and models that accelerate library learning, innovation, and collaboration. As a member-driven cooperative, OCLC is guided by representatives from member institutions who help shape programs, policies, strategy, and services, ensuring the organization responds to the evolving needs of the global library community.
