[edit] History

It was incorporated on July 6, 1967 as the not-for-profit Ohio College Library Center.^[3] More than 72,000 libraries in 170 countries and territories use OCLC services to locate, acquire, catalog, lend and preserve library materials.^[4] The organization was founded by Fred Kilgour, and its head office is located in Dublin, Ohio, U.S.

[edit] Services

OCLC provides bibliographic, abstract and full-text information to anyone.

OCLC and its member libraries cooperatively produce and maintain WorldCat—the OCLC Online Union Catalog, the largest online public access catalog (OPAC) in the world. WorldCat has holding records from public and private libraries worldwide. The Open WorldCat program makes records of library-owned materials in OCLC's WorldCat database available to Web users on popular Internet search, bibliographic, and bookselling sites. In October 2005, the OCLC technical staff began a wiki project allowing readers to add commentary and structured-field information associated with any WorldCat record.

Until August 2009, when it was sold to Backstage Library Works, OCLC owned a preservation microfilm and digitization operation called the OCLC Preservation Service Center, with its principal office in Bethlehem, Pennsylvania, U.S.

[edit] Online database

OCLC has a database for cataloging and searching purposes which is used by librarians and the public. The current computer program, Connexion, was introduced in 2001, and its predecessor, OCLC Passport, was phased out in May 2005.

This database contains records in MAchine Readable Cataloging (MARC) format contributed by library catalogers worldwide who use OCLC as a cataloging tool. These MARC format records are then downloaded into the libraries' local catalog systems. This allows libraries to find and download records for materials to add to their local catalog without the lengthy process of cataloging each individually.

As of February 2007, their database contained over 1.1 billion cataloged items. It is the world's largest bibliographic database. Connexion is available to professional librarians as a computer program or on the web at connexion.oclc.org.

WorldCat is available to the public for searching a web-based service called FirstSearch, as well as through the Open WorldCat program.

The Online Computer Library Center acquired the trademark and copyrights associated with the Dewey Decimal Classification System when it bought Forest Press in 1988.

WebJunction is a division of OCLC funded by a grant from the Bill and Melinda Gates Foundation.

QuestionPoint reference management service provides libraries with tools to communicate with users. This around-the-clock reference service is provided by a cooperative of participating global libraries.
