In 1974 the New York Public Library and libraries of Columbia, Harvard, and Yale universities founded RLG (Research Libraries Group), based in Mountain View, California. The New York Times called this "a sweeping and controversial program of combined operations." RLG was incorporated in 1975 and existed as a "new kind of practical resource-sharing consortium" until it merged with the OCLC library consortium in 2006.
