The Magellan Systems Corporation Records document various aspects of the development of several different Magellan GPS devices through engineering, research, design, manufacturing, and marketing records. Magellan Systems Corporation introduced the first hand-held differential GPS product and the conpany's focus was on research, product engineering, and design activities for GPS receivers. The collection includes correspondence and internal company reports and memoranda; design drawings; research notes; engineering notebooks, technical notes, schematics; photographs, slides and negatives; video and audiocassettes; advertisements; product literature, magazine articles and newspaper clippings; press releases; and user guides and manuals.

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.
