The Sophie Frye Bass Library has moved to the new MOHAI Resource Center in the Georgetown section of Seattle, located at 5933 6th Avenue South.
The museum's Sophie Frye Bass Library preserves and provides access to over 3 million historic photographs, as well as manuscripts and archival holdings, maps, books, posters, motion pictures and printed ephemera. Our collections cover the Seattle metropolitan area, and certain subjects of the rest of Washington State and Alaska. Archival holdings include business and organization records, personal papers, photographers' collections, and historical research documents.
Two affiliate organizations, the Puget Sound Maritime Historical Society and the Black Heritage Society of Washington State, maintain their collections in the library and provide access by appointment.
