William Duncan Strong's early interest was in zoology, but, while an undergraduate at the University of California, he was brought into anthropology under the influence of Alfred Louis Kroeber. He conducted archaeological and ethnological field research in several areas of the New World and was the first professionally trained archaeologist to focus on the Great Plains, where he applied the so-called direct historical method, working from known history in interpreting archaeological sites. Strong's papers include correspondence, field notes, diaries, newspaper clippings, teaching notes and student papers, manuscripts of his writings, writings by other authors, papers from the various organizations in which he served, maps, and a considerable number of photographs from his field work. The materials date from 1902 to 1965, with most of the materials being from 1927 to 1955.

The records of the American Federation of Arts (AFA) provide researchers with a complete set of documentation focusing on the founding and history of the organization from its inception through the 1960s. The collection measures 79.8 linear feet, and dates from 1895 through 1993, although the bulk of the material falls between 1909 and 1969. Valuable for its coverage of twentieth-century American art history, the collection also provides researchers with fairly comprehensive documentation of the many exhibitions and programs supported and implemented by the AFA to promote and study contemporary American art, both nationally and abroad.

The Joseph Cornell Study Center collection measures 196.8 linear feet and dates from 1750 to 1980, with the bulk of the material dating from 1930 to 1972.

The collection also includes diaries and notes, financial and estate papers, exhibition materials, collected artifacts and ephemera, photographs, correspondence, and the papers of Robert Cornell (1910-1965) and Helen Storms Cornell (1882-1966), the artist's brother and mother.

The collection includes extensive correspondence files, reference material on American and European collectors and their collections, inventory and stock records, financial records, exhibition files, auction files, and the records of subsidiary companies.

This collection contains over 37,000 35mm slides, 3,000 glass lantern slides and garden files that may include descriptive information, photocopied articles (from journals, newspapers, or books), planting lists, correspondence, brochures, landscape plans and drawings. Garden files were compiled by Garden Club of America (GCA) members for most of the gardens included in the collection. Some gardens have been photographed over the course of several decades; others only have images from a single point in time. In addition to images of American gardens, there are glass lantern slides of the New York Flower Show (1941-1951) and trips that GCA members took to other countries, including Mexico (1937), Italy, Spain, Japan (1935), France (1936), England (1929), and Scotland. A number of the slides are copies of historic images from outside repositories including horticultural and historical societies or from horticultural books and publications. The GCA made a concerted effort in the mid-1980s to acquire these images in order to increase its documentation of American garden history. Because of copyright considerations, use of these particular images may be restricted.
