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.

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.
