A global leader in library technology

OCLC was established in 1967, when a group of Ohio college and university leaders collaborated to share resources, expand access to library information and reduce the costs of doing so. From that beginning, OCLC has grown to be a global leader in library technology. As a not-for-profit library cooperative, we provide innovative library services, research and development programs to our nearly 17,000 member libraries representing more than 120 countries around the world.

Together with member libraries, we connect people to the resources they need to fuel learning, research and innovation. WorldCat, cooperatively produced and maintained by OCLC and member libraries, is the largest database of library bibliographic data in the world, with information on 2.3 billion items (and growing), including books, databases, songs, maps, genealogical records, articles and more.

Our staff of 1,200 around the world join our member libraries and partners in making breakthroughs possible. We are proud to be part of the Central Ohio community, a global hub for technology, creativity, innovation and learning. Learn more at oclc.org and follow us on FacebookTwitter and LinkedIn.
