National Portrait Gallery

Photograph archives and collections online include photographic media and artist renderings, various Native American items digitally available to view by search term, date, or topic, but many lack the name of the subjects in photographs, more often a location or cultural label is given. "The Library's collection consists of more than 180,000 books, exhibition catalogues, catalogues raisonné, periodicals, and dissertations that concentrate on American art, history, and biography, with supporting materials on European art... The Catalog of American Portraits (CAP), part of the National Portrait Gallery’s Office of Collections Information and Research, is a national portrait archive maintaining information and images for more than 200,000 portraits of prominent American subjects or by prominent American artists." The physical collections have varying levels of accessibility for research, see website for details.
