The records of Jacques Seligmann & Co. measure approximately 203.1 linear feet and date from 1904 to 1978, with bulk dates from 1913 to 1974. 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. The collection is an invaluable resource in tracing the provenance of particular works of art and provides a comprehensive view of the activities of collectors and art dealers in the years leading up to and following World War II.

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 collection documents Duke Ellington's career primarily through orchestrations (scores and parts), music manuscripts, lead sheets, transcriptions, and sheet music.

The gallery's activities are also recorded through correspondence, client files, gallery invoices, inventories, business and financial records, printed materials, scrapbooks, photographic materials of artwork, and estate records for the John Marin estate and Sergio Stella estate (Joseph Stella).
