The Macbeth Gallery records provide almost complete coverage of the gallery's operations from its inception in 1892 to its closing in 1953. Through extensive correspondence files, financial and inventory records, printed material, scrapbooks, reference and research material, and photographs of artists and works of art, the records document all aspects of the gallery's activities, charting William Macbeth's initial intention to lease his store "for the permanent exhibition and sale of American pictures" through over sixty years of success as a major New York firm devoted to American art. The collection measures 131.6 linear feet and dates from 1838 to 1968 with the bulk of the material dating from 1892 to 1953.

The papers document the life and work of William R. Hutton, a civil engineer during the late 1800s to the early 1900s. Materials include diaries, notebooks, correspondence, letterpress copy book, printed materials, publications, specifications, photographs, drawings, and maps that document the construction of several architectural and engineering projects during this period. Most notable are the records containing information related to the construction of the Chesapeake and Ohio Canal, Hudson River Tunnel, the Washington Aqueduct, the Kanawha River Canal, and the Washington/Harlem River Bridge. There are also several records about railroads in the state of Maryland, the District of Columbia and elsewhere, including the Western Maryland Railroad, Baltimore and Ohio Railroad, Colorado Midlands Railway, Baltimore and Drum Point Railroad, the Northern Adirondack Railroad, and the Pittsfield and Williamstown Railroad. The records can be used to track the progression of these projects, and engineering innovation during the late 1800s to the early 1900s.

The papers of contemporary and folk art curator, historian, and consultant Dorothy C. Miller measure 34.6 linear feet and date from 1853-2013, with the bulk of the material dating from 1920 to 1996.

Found are scattered biographical materials, extensive correspondence and subject files, and project files for her art consulting work for the Rockefeller family, Rockefeller University, Chase Manhattan Bank, the Port Authority of New York and New Jersey, the World Trade Center, and other miscellaneous corporate and private clients. Miller's work as a trustee and committee member of various public and private boards and commissions is also represented here. Additionally, the papers contain Miller's research files on Edward Hicks and folk art, and a small number of files of her husband Holger Cahill about his work as Director of the Federal Art Project. There is a scattered documentation of Miller's early curatorial work with Holger Cahill on the First Municipal Art Exhibition (1934) held at the RCA Building in Rockefeller Center. Also found is Dorothy Miller's collection of artists' Christmas cards and photographs of Miller and others. An addition to the papers includes biographical material; family papers; correspondence; professional files; art collection and client files; printed material; and photographic material.

This collection documents his research and professional activities through correspondence, research notes, data, manuscripts, publications, and photographs. Represented in the collection is his fieldwork in Mexico, Peru, Venezuela, and Costa Rica.

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 papers of arts administrator, museum director, collector, dealer, and editor Charles M. Kurtz (1855-1909), measure 27.74 linear feet and date from 1843-1990 (bulk dates 1884-1909). The bulk of the collection consists of detailed chronological correspondence between Kurtz and his wife and family, friends, colleagues, and business associates that documents many notable exhibitions, galleries, museums, private collections, as well as cities, people, and events of the period. Also found in the collection are Kurtz's diaries, scrapbooks, printed materials, and photographs.

These papers reflect the professional lives of Alice Cunningham Fletcher (1838-1923), an ethnologist with the Peabody Museum of Harvard and collaborator with the Bureau of American Ethnology, and Francis La Flesche (1856-1923), an anthropologist with the Bureau of American Ethnology. Due to the close professional and personal relationship of Fletcher and La Flesche, their papers have been arranged jointly. The papers cover the period from 1874 to 1939. Included in the collection is correspondence, personal diaries, lectures, field notes and other ethnographic papers, drafts, musical transcriptions, publications by various authors, maps and photographs.
