The records document the work of consulting engineers and bridge builders, Ralph Modjeski (1861-1940) and Frank Masters (1883-1974) of Harrisburg, Pennsylvania.

Harrington was a Bureau of American Ethnology ethnologist involved in the study of over one hundred American tribes. His speciality was linguistics. Most of the material concerns California, southwestern, northwestern tribes and includes ethnological, archeological, historical notes; writings, correspondence, photographs, sound recordings, biological specimens, and other types of documents. Also of concern are general linguistics, sign language, writing systems, writing machines, and sound recordings machines. There is also some material on New World Spanish, Old World languages. In addition, there are many manuscripts of writings that Harrington sketched, partially completed, or even completed but never published. The latter group includes not only writings about anthropological subjects but also histories, ranging from a biography of Geronimo to material on the history of the typewriter. The collection incorporates material of Richard Lynch Garner, Matilda Coxe Stevenson, and others. In his field work, Harrington seems sometimes to have worked within fairly firm formats, this especially being true when he was "rehearing" material, that is in using an informant to verify and correct the work of other researchers. Often, however, the interviews with informants (and this seems to have been the case even with some "rehearings") seem to have been rather free form, for there is a considerable intertwining of subjects. Nevertheless, certain themes frequently appear in his work, including annotated vocabularies concerning flora and fauna and their use, topography, history and biography, kinship, cosmology (including tribal astronomy), religion and philosophy, names and observations concerning neighboring tribes, sex and age division, material culture, legends, and songs. The fullness of such materials seems to have been limited only by the time Harrington had to spend with a goup and the knowledge of his informants.

The collection consists of a wide range of materials--ephemera, trade literature, correpsondence, photographs, maps, plans, schematics, pamplets, brochures, postcards, calendars--documenting the subject of bridges.

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 W. Atlee Burpee & Company records, dated circa 1873-1986, document the firm's business activities developing plant varieties, working with contract seedsmen, and marketing and selling seeds. They include seed trial records, seed contracts, sales and acccounting records, inventories, office correspondence, seed catalogs, promotional and instructional materials, advertisements and advertising reports, contest letters, daybooks, photographs, reference materials, and other items relating to the company and some of its competitors. The collection also includes Burpee family papers.

The collection forms a documentary record of over half a century of the history of radio, with the greatest emphasis on the period 1900-1935. The collection includes materials that span the entire history of the growth of the radio industry. It is useful for those historians and other researchers interested in technological development, economic history, and the impact of applications of technology on American life.

The engineering firm that became Lockwood Greene was founded by David Whitman, a mill engineer, in 1832. Amos D. Lockwood, a consultant, succeeded Whitman and entered a partnership with Stephen Greene in 1882. The firm specialized in industrial engineering and construction; they designed and built a wide variety of structures and work environments worldwide over the next century. Lockwood Greene was acquired by CH2M HILL in December, 2003. Before its acquisition by CH2MHILL it was reportedly the oldest industrial engineering, construction, and professional services firm in the United States.

This collection consists of the corporate records of the Curtiss-Wright Corporation. Included in the collection are technical and engineering reports of Curtiss-Wright Airplane Division's operations in St. Louis (Robertson), MO (1935-1945) and Buffalo, NY, (1932-1945), as well as AAS Material Division and AAF Air Technical Services Command memorandum reports collected by Curtiss-Wright's St. Louis and Buffalo technical reference libraries. The collection also contains the files of Curtiss-Wright's Patent Department, which hold records of patents filed by Curtiss-Wright and patent-infringement cases involving Curtiss-Wright. Also included in the collection are specifications issued by and photos commissioned by the Keystone Aircraft Corporation (Huff-Daland Airplanes, Inc. until March 1927), which had been acquired by Wright in 1928 along with Loening Aeronautical Engineering Corp., and formed the Keystone Division of Curtiss-Wright until 1932 when Keystone's Bristol, PA factory closed its doors. The collection also contains financial records of the Curtiss-Wright Airports Corporation, which was liquidated in 1936, as well as an extensive negative collection featuring Curtiss-Wright aircraft from the 1930s and 1940s, concentrated especially on the war years.

Consists of photographs collected by the United States National Museum (USNM) Division of Ethnology and later by the Smithsonian Office of Anthropology (SOA). Coverage is worldwide outside North America. Most of the items are photographic prints, some in albums. There are also negatives, photomechanical prints, artwork, and newsclippings. For the …
