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 Historic Gardens Stereograph Collection includes 807 stereographs that depict various public gardens, parks, and tourist attractions throughout the United States, with an emphasis on features related to horticulture and landscape design, including plants, garden furniture, and topiaries. Most, but not all views, show exterior features. A number of stereographs indicate the photography studio on the recto or verso, as well as a series or image number. Many include a brief caption; some include a lengthy description on the verso. Few are dated.

The Richard Marchand Historical Postcard Collection contains approximately 1,200 35mm slide reproductions of postcard images depicting early twentieth century architectural and garden views of over 600 private estates throughout the United States.

The Ken Druse Garden Photography Collection contains approximately 45,000 film transparency and 35mm slide images, dating from 1978 to 2005, of gardens, garden features, and flora photographed by garden writer and photographer Ken Druse. The photographic images document numerous private and public gardens throughout the United States and a few in Canada. Many have appeared in Druse's own books and articles as well as those by other writers. Approximately half of the collection is arranged according to specific garden, the other half by garden feature. A small portion of the collection consists of slide lectures given by Druse. Some images are identified with general captions and dates. Images documenting specific gardens are sometimes accompanied by handwritten notes, garden descriptions, and articles. Annotations appearing on certain images indicate the publication in which they appeared. The collection includes 'outtakes' or bracketed images that give insight into Druse's photo shooting process.
