OCLC, currently incorporated as OCLC Online Computer Library Center, Incorporated, is an American nonprofit
OCLC began in 1967, as the Ohio College Library Center, through a collaboration of Ohio university presidents, vice presidents, and library directors who wanted to create a cooperative, computerized network for Ohio libraries. The group first met on July 5, 1967 on the campus of
Membership in OCLC is based on use of services and contribution of data. Between 1967 and 1977, OCLC membership was limited to institutions in Ohio, but in 1978, a new governance structure was established that allowed institutions from other states to join. In 2002, the governance structure was again modified to accommodate participation from outside the United States.
As OCLC expanded services in the United States outside Ohio, it relied on establishing strategic partnerships with "networks," organizations that provided training, support and marketing services. By 2008, there were 15 independent United States regional service providers. OCLC networks played a key role in OCLC governance, with networks electing delegates to serve on OCLC Members Council. During 2008, OCLC commissioned two studies to look at distribution channels; at the same time, the OCLC Members Council approved governance changes that had been recommended by the Board of Trustees which severed the tie between the networks and governance. In early 2009, OCLC negotiated new contracts with the former networks and opened a centralized support center.
