The projects in this collection represent the history of a firm that lasted nearly a century. The roots of the firm can be traced back to Hermann J. Schwarzmann, a German-born architect who designed the Philadelphia Centennial of 1876. Schwarzmann soon partnered with Albert Buchman and practiced with him until 1887. Unfortunately no drawings survive from the two earliest firms. This collection begins with records from the partnership of Buchman & Deisler (circa 1888-1899), followed by a succession of partnerships until the dissolution of the firm: Buchman & Fox (1899-1917), Buchman & Kahn (1917-1930), Ely Jacques Kahn Architects (1930-1940), and Kahn & Jacobs (1940-1973). The bulk of the collection documents the firms' work from 1893 until 1950. The collection includes approximately 8,250 architectural drawings for projects located primarily in New York City that were designed or altered by Kahn & Jacobs and the various predecessor partnerships. Major projects include the Bergdorf Goodman Department Store (1927); Bloomingdale's Department Store (1903-1917); the Bonwit Teller Department Store at Fifth Avenue and 38th Street (1911); the Film Center building (1928-1932); the original New York Times Building at 42nd Street and Broadway (1915-1920); and the Squibb Building (1929-1951), all in New York City. Researchers will also find drawings for the Oppenheimer-Collins Company buildings in Brooklyn (1915-1928), New York City (1906-1930), Philadelphia (1923), and Pittsburgh (1919-1928).

Files of the company, 1911-1920, much of which consists of unsucessful architectural bid documents, each noting the architect, building, and location, as well as estimated costs, sketches, and related correspondents. These bid documents represent commissions not awarded to NYATCC, and do, in some cases, indicate the outcome of the bid. Architects represented include McKim, Mead & White; Cass Gilbert; George Post; D.H. Burnham & Company; Warren & Wetmore, Schwartz & Gross, and many others. Also includes correspondence and office memoranda, including some describing the formative years, 1911-1914, of the National Terra Cotta Society, trade catalogs, and job photographs. Also, two albums containing photographs of sample pieces of terra cotta, and month by month construction records for three buildings, including the American Theater (42nd Street, New York, 1892) by Charles Coolidge Haight; the Renaissance Apartments (Brooklyn, N.Y., 1889) and the Imperial Apartments (Brooklyn, N.Y., 1890) both by Montrose Morris.
