This small collection documents the Damon, Doudt Corporation's offer to purchase Ellis Island from the United States Government and to redevelop the site with architectural plans envisioned by Frank Lloyd Wright and executed by the Taliesin Associated Architects after Wright's death in 1959.

These albums contain mounted black-and-white photographic prints documenting historic sites and structures along the East Coast of the United States, from the South to New Hampshire, created and collected by architect and historian John Mead Howells. These albums appear to have been created as reference sources for Howell's publications LOST EXAMPLES OF COLONIAL ARCHITECTURE (New York, W. Helbrvn, 1931), THE ARCHITECTURAL HERITAGE OF THE PISCATAQUA (New York: Architectural Book Publishing Company, 1937), and THE ARCHITECTURAL HERITAGE OF THE MERRIMACK (New York: Architectural Book Publlishing Company, 1941). However, many additional images may be found in these albums than were used in these publications. The images were taken during the second half of the 19th-century and the early 20th-century of historic buildings and sites constructed during the 18th- and 19th-centuries. Most images have annotations and caption information in typescript or in Howell's own hand. Howells collected most of the images from a variety of sources, including the Frank Cousins image collection at the Essex Institute, the Society for the Preservation of New England Antiquities, the Metropolitan Museum of Art, architect Ogden Codman, and the Historic American Buildings Survey. The remainder were taken by Howells himself.

Architectural drawings and photographs of Litchfield's designs for Yorkship village (housing for ship workers during World War I near Camden, N.J.); Public Library, St. Paul, Minn.; memorial to Theodore Roosevelt at Oyster Bay, Long Island, N.Y.; 800 Park Avenue and other New York City apartment houses; Albany Post Office, Albany, N.Y. (designed by Gander, Gander & Gander, with Litchfield as consulting architect); and other projects.

This small collection contains primarily correspondence, itineraries, and papers related to Fitch's publications, travel, and the administration of Columbia University's Historic Preservation program. There are copies and drafts of several articles and reports generated for various organizations authored by Fitch and others (all reports are noted in italics in the spreadsheet). Also included is the unfinished manuscript of Fitch's final book project on American architecture. Of particular note among the reference materials are fifty-two photographs of Richard Neutra's VDL Research House in Los Angeles, some taken by architectural photographer Julius Shulman.

This collection documents, though partially, the professional life of architectural and art historian, librarian, and preservationist James Grote Van Derpool (1903-1979). Generally, this collection contains correspondence, office files, printed materials, photographs, slides, literary productions, and legal documents. A large portion of this collection consists of papers that reflect the activities of Van Derpool as "defender of the architectural treasures," including records and papers relating to research done for the National Parks Service. Also in the collection are records of lectures on the history of American architecture given at educational institutions, clubs, societies, business organizations, and religious and cultural group meetings. There are also papers relating to Van Derpool's research on the history of Avery Library at Columbia University and the life and work of Italian architect Leon Battista Alberti. Additionally, there is a group of records of the Advisory Committee of the University of Illinois for the time period when Van Derpool was chairman. Van Derpool's book collection was incorporated into the permanent collection of Avery Library after his death.
