OCLC is the world's largest library cooperative, facilitating cataloging, interlibrary loans, and other services through its main products and services. Originally founded in 1967 as the Ohio College Library Center to merge library catalogs electronically and reduce costs, OCLC now hosts WorldCat, the world's largest database of library holdings and metadata. WorldCat allows users to search across library collections and locate items through library discovery tools. OCLC provides additional services such as QuestionPoint for virtual reference and WorldShare for library management and metadata collection.
