and John Twachtman (1853–1902). F|S Online The Freer|Sackler provides several online resources for exploring the art and culture of Asia and its American art collections. Besides the collections objects viewable online, thousands of photographs, archeological diaries, maps, and archaeological squeezes (impressions of carvings) have been digitized and are used by researchers from around the world. F|S Archives and Library The Freer Sackler Archives houses over 120 important manuscripts collections relevant to the study of America's encounter with Asian art and culture. The core collection is the personal papers of gallery founder Charles Lang Freer, which includes his purchase records, diaries, and personal correspondence with public figures such as artists, dealers and collectors. Freer's extensive correspondence with James McNeill Whistler forms one of the largest sources of primary documents about the American artist. Other significant collections in the Archives includes the papers (notebooks, letters, photography, squeezes) and personal objects of the German archaeologist Ernst Herzfeld (1879–1946), documenting his research at Samarra, Persepolis and Pasargadae. The papers of Carl Whiting Bishop Dwight William Tryon, Myron Bement Smith, Benjamin March and Henri Vever are also located at the Archives. The Archives also holds over 125,000 photographs of Asia dating from the 19th and early 20th centuries. Highlights of photographic holdings include the Henry and Nancy Rosin Collection of 19th century photography of Japan, the 1903-1904 photographs of the Chinese Empress Dowager Cixi, and photographs of Iran by Antoin Sevruguin. The Freer|Sackler Library is the largest Asian art research library in the United States. Open to the public five days a week (except federal holidays) without appointment, the library collection consists of more than 86,000 volumes, including nearly 2,000 rare books. Half the volumes are written and catalogued in Asian languages. Originating from the collection of four thousand monographs, periodical issues, offprints, and sales catalogues that Charles Lang Freer donated to the Smithsonian Institution as part of his gift to the nation, the F|S Library maintains the highest standards for collecting materials an active program of purchases, gifts, and exchanges. In July 1987 the library moved to its new home in the Arthur M. Sackler Gallery. Today it supports activities of both museums, such as collection development, exhibition planning, publications, and other scholarly and educational projects. Its published and unpublished resources—in the fields of Asian art and archaeology, conservation, painting, sculpture, architecture, drawings, prints, manuscripts, books, and photography—are available to museum staff, outside researchers,
