Drawings made by Raisman while a student at Columbia University's School of Mines, Engineering and Chemistry from 1894 to 1898. The majority of the drawings are ink on paper or vellum and are studies of various shapes, valves, arches, and bridges.

Three sketchbooks; the first, 1893-1894, containing sketches from his student years at the Columbia School of Mines, Department of Architecture (he received his degree in 1894); the second, 1894-1896, containing sketches made as a student at the Ecole des Beaux-Arts in Paris; and the third, circa 1896-circa 1905, containing sketches for a variety of projects and designs. Buildings and other structures depicted include the Academy of Music on 14th Street, New York City (a seating plan); Wells Fargo Bank Building, Portland, Oregon, 1910; Reunion Hall, Princeton University, 1902; lantern for the Aetna Building, Hartford, Connecticut; Woodland Street entrance to Kinney Park, Hartford, Connecticut, 1905 (some drawings are by others). Program notes from the classes of Paul Blondel and J. Gaudet at the Ecole des Beaux Arts are included. Also, designs (some done in partnership with Joseph Urban) for proposals for the Metropolitan Opera Company on various sites in New York City, circa 1920s; and designs for shopping and music centers in New York City, to 1936.

This collection contains architectural drawings by various delineators and photographs of completed buildings designed by Charles Coolidge Haight. These projects include General Theological Seminary; the School of Mines at Columbia University; Christ Church, built in 1860; St. Ignatius Chapel, built in 1902; and Trinity School--all in New York City. Also included are the Chapel of Saint Cornelius the Centurion on Governors Island, New York; buildings at Yale University; and miscellaneous and unidentified projects. Additionally found in the collection are a contract and specifications from 1881 for a hospital for contagious diseases to be built for the New York City Health Department on North Brother Island in New York City, as well as reproductions of architectural drawings for this hospital.

This small collection contains primarily Detwiller's student drawings, notes, course materials, books, class photographs, and graduation announcements from the period of his study at Columbia University from 1881 to 1885. These materials are supplemented by a small group of Detwiller's childhood sketchbooks, drawings and office papers created by Detwiller during his practice as a professional architect, and other scrapbooks and ephemeral items relating to Detwiller's family and personal interests, spanning the years 1874 to 1940.

Included are architectural drawings, surveys, maps, and site proposals, for Columbia's Morningside Heights campus, designed primarily by McKim, Mead & White. Other architects represented include Adams & Woodbridge; Arnold Brunner (who designed the School of Mines); Eggers & Higgins; the Columbia University Buildings and Grounds Department; Howells and Stokes (designed St. Paul's Chapel); Reinhard, Hofmeister and Wahlquist; and James Gamble Rogers. Drawings for buildings no longer in existence or never constructed and drawings for later alterations, are included. Architectural drawings of the Bloomingdale Insane Asylum, and surveys of the asylum site prepared for Columbia, 1888-1894. Also included are site plans and proposals, surveys, and maps, circa 1890s-1910s, showing the surrounding area, including such institutions as the Jewish Theological Seminary, St. Luke's Home, Cathedral of St. John the Divine, Grant's Tomb, and others. Drawings for the Womans's Hospital in the State of New York (designed by Allen & Collens, erected 1903, demolished in the 1970s), circa 1903-1914, are also included. This building was used to house the Columbia School of the Arts in the 1960s since it was located near the campus.

Included are drawings--from preliminary sketches to finished renderings--done by students in the architecture program at the School of Mines at Columbia and, later, at the School of Architecture at Columbia. The bulk of these were done circa 1884-1912, during the tenures of Deans William Robert Ware (1881-1903) and A.D.F. Hamlin (1903-1912). Included in collection are student drawings by William A. Boring, Harry Allan Jacobs, Benjamin Wistar Morris, Jr., Julian Clarence Levi, Arthur Ware, Talbot Faulkner Hamlin, Leopold F. Arnaud, Perry Coke Smith, Theodor Karl Rohdenburg, and Aladar Olgyay. Also, drawings done by architecture students at the Massachusetts Institute of Technology, circa 1880s; a photograph, undated, of William Robert Ware; and one drawing, 1879, by architect Cass Gilbert.

Also, typescripts of lectures delivered by Boring in architecture courses at Columbia, 1932-1933, miscellaneous typescripts of articles and printed materials, 1930-1933, and a typescript of Boring's autobiography, MEMORIES OF THE LIFE AND WORK OF WILLIAM A. BORING, circa 1937. Also included are four sketches by Henri Gauthier, Edward Tilton, Maurice Sashin, and Joseph Laudin.
