The Cook Labs records, which date from 1939-2002, document the activities of audio engineer Emory Cook and his label Cook Labs. The contents include business records, materials relating to recording artists, photographs, and production materials, as well as phonograph records, master recordings and unpublished recordings produced by or associated with the Cook Labs label. The collection also contains two interviews conducted with Emory Cook in 1990: one by Jeff Place and one by Anthony Seeger and Nicholas Spitzer. There are several physical objects relating to Cook Labs including a bag of powdered vinyl, a binaural playing arm, and a condenser microphone.

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 in photographs, scrapbooks, notebooks, correspondence, stock ledgers, annual reports, and financial records, the evolution of the telegraph, the development of the Western Union Telegraph Company, and the beginning of the communications revolution. The collection materials describe both the history of the company and of the telegraph industry in general, particularly its importance to the development of the technology in the nineteenth and twentieth centuries. The collection is useful for researchers interested in the development of technology, economic history, and the impact of technology on American social and cultural life.
