The Albert Duveen collection of artists' letters and ephemera measures 1.1 linear feet and dates from 1807 to 1946. Unrelated letters written by over 170 mostly 19th and early 20th century American artists are found in this compiled collection of art critic, dealer, and collector Albert Duveen. Additional ephemera includes printed material and photographs of artwork.

The Library of Congress Copyright Deposit Collection is comprised of 2,335 photomechanical reproductions of works by 741 artists (mostly American). The large-format prints, deposited with the Library of Congress for copyright between 1890 and 1945, represent a broad range of nineteenth- and twentieth-century American art.

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.
