J. Paul Getty Trust
The Getty Research Institute (GRI), located at the Getty Center in Los Angeles, California, is "dedicated to furthering knowledge and advancing understanding of the visual arts".  GRI maintains a research library, organizes exhibitions and other events, sponsors a residential scholars program, publishes books, and maintains electronic databases including a Semantic Web service. The GRI was originally called the "Getty Center for the History of Art and the Humanities", and was conceived as early as 1983. Among other holdings, GRI's research library contains about 900,000 volumes of books, periodicals, and auction catalogs; special collections; and two million photographs of art and architecture. The library also includes the trust's "Institutional Archives" which document the activities of the trust's various programs.
