OCLC Online Computer Library Center
Founded in 1967, OCLC Online Computer Library Center is a nonprofit, membership, computer library service and research organization dedicated to the public purposes of furthering access to the world's information and reducing the rate of rise of library costs. More than 72,000 libraries in 170 countries and territories around the world have used OCLC services to locate, acquire, catalog, lend and preserve library materials.OCLC and its member libraries cooperatively produce and maintain WorldCat—the OCLC Online Union Catalog.
WorldCat is a global network of library-management and user-facing services built upon cooperatively-maintained databases of bibliographic and institutional metadata. WorldCat enhances productivity across the full range of library workflows—from cataloging to resource sharing to discovery and delivery—by intelligently reusing contributed data, and makes library resources more visible on the Internet by distributing data across a growing number of partner services and Web technologies.
