OCLC, a global library cooperative, supports thousands of libraries in making information more accessible and more useful to people around the world. OCLC helps libraries share the world’s collected knowledge to fuel learning, research, and innovation.

Together, OCLC member libraries and publishing partners contribute to and maintain WorldCat, the world’s most comprehensive database of information about library collections. By cooperatively contributing, enhancing and sharing bibliographic data through WorldCat, libraries connect people to cultural and scholarly resources in libraries worldwide.

Just as WorldCat provides a centralized resource for library data, WorldShare provides a centralized library services platform for managing activities, service delivery and workflows. Libraries that operate on the WorldShare Platform benefit from a global, interconnected web architecture that provides flexible access to WorldCat data and a variety of web services and APIs that simplify library workflows and empower library staff.

OCLC also supports libraries worldwide with additional solutions to preserve and safely share archival collections, support collection development and deselection activities, organize collections in the library, answer users’ reference questions, share resources between libraries, and help users find and get the information they need.

OCLC consists of librarians, technologists, researchers, leaders, and learners who share a passion for connecting people with knowledge. We believe that what is known must be shared. Together, through our collaboration and understanding, we make breakthroughs possible.
