Collection includes James Renwick's sketches, 1813, for the layout of Columbia University's second campus on Park Row (there have been four campuses to date: the first on Wall Street, the third on 49th Street and Madison Avenue, and the current campus in Morningside Heights), and a medal awarded him, 1824, by the Franklin Institute, Philadelphia. James Renwick, Jr. is represented by his architectural drawings of St. Patrick's Cathedral, New York, which he designed. Some of the drawings are signed by Bertram Grosvenor Goodhue. Also, published drawings of the Cathedral, 1886; negatives and photographs, circa 1860s, showing the Cathedral under construction; interior and exterior photographs, circa 1930s-1960s, of the Cathedral; and photographs of Grace Church, New York, also designed by James Renwick, Jr. Renwick family correspondence, 1930s, and typescript copies of 19th century Renwick family correspondence relating to family history and genealogy; photographs of James Renwick, Jr; typescript copies of family Bible records, 1792-1863; Renwick coat of arms.

Architectural drawings for residence, public and commercial buildings, churches, university buildings, and other structures, ca. 1880s-1925, many of which are located in Maine. These were done by Stevens while working independently, in partnership with his son John Howard Stevens, and while a member of architectural firms Fassett and Stevens (with offices in Portland, Maine and Boston, Mass.) and Stevens and Cobb. One unidentified photograph of a house is included. Also included are drawings Stevens did for the book EXAMPLES OF AMERICAN DOMESTIC ARCHITECTURE.

The bulk of this collection consists of more than 22,000 black and white photographic negatives and more than 10,600 black and white photographic prints documenting commercial, institutional, religious, and residential architecture throughout the United States, with particular emphasis on sites in the mid-Atlantic region. These images date from the mid-1930s to Molitor's retirement in the mid-1980s, with the great majority of images created between 1946 and 1980. Also included in the collection are images of landscapes, industrial design, portraits, and events of personal significance to Molitor. In some select cases, color prints, color negatives, color transparencies, and 35mm slides are also available in addition to or instead of the black and white negatives and prints. Researchers are also advised that documents in this collection indicate that when faced with a lack of storage space in 1973, Molitor contacted clients to return inactive negatives that they had comissioned before 1955. In at least some cases, those clients declined to accept their negatives and Molitor subsequently destroyed the images. Thus, this collection has lacunae in the negatives series.

Taylor from 1907 until 1962; professional papers from various committees and societies Levi was associated with; personal papers and photographs, including documentation on his family and office, his academic and professional recognitions, public events, travels and social gatherings as a former Columbia alumnus; and various prints and photographs of buildings and European artists collected by Levi throughout his life.
