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.

The records of the Downtown Gallery date from 1824 to 1974 (bulk 1926-1969) and measure 109.56 linear feet. The records present a comprehensive portrait of a significant commercial gallery that operated as a successful business for more than forty years, representing major contemporary American artists and engendering appreciation for early American folk art. There is an unprocessed addition to this collection dating circa 1970 of a single financial/legal document.

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.
