OCLC (Online Computer Library Center) was created in 1971 as a non-profit organization dedicated to furthering access to the world's information while reducing information costs. The OCLC Online Union Catalog - renamed WorldCat much later - began as the union catalog of the university libraries in the State of Ohio. Over the years, OCLC became a national and then worldwide library cooperative, and WorldCat the largest library catalog in the world. In early 1998, WorldCat had 38 million records in 400 languages - with transliteration for non-Roman languages) - and an annual increase of 2 million records. In 1998, 27,000 libraries in 65 countries were using OCLC services (paid subscription) to manage their collections and provide online reference services. WorldCat has only accepted one bibliographic record per document, unlike RLIN (Research Library Information Network), launched by the Research Libraries Group (RLG) in 1980. RLIN accepted several records per document, with 88 million records in early 1998. Members of RLG were mainly research and specialized libraries. RLIN was later renamed the RLG Union Catalog. Its free web version, RedLightGreen, was launched in fall 2003 as a beta version, and in spring 2004 as a full version. This was a major move, not only for library members, but for all internet users, who could also access it for free. In 2005, WorldCat had 61 million bibliographic records in 400 languages, from 9,000 member libraries in 112 countries. In 2006, 73 million bibliographic records were linking to one billion documents available in these libraries. In August 2006, WorldCat began to migrate to the web through the beta version of its new website worldcat.org. Member libraries now provided free access to their catalogs and electronic resources: books, audiobooks, abstracts and full- text articles, photos, music CDs and videos. RedLightGreen ended its service in November 2006, and RLG joined OCLC. 2000: INFORMATION IS AVAILABLE IN MANY LANGUAGES = [Overview]
