"A collection of books, portfolios, and pamphlets about architecture and other closely related subjects published in the U.S. between the Revolution and 1900. The emphasis of the collection is on builders and house pattern books, but a number of descriptive works such as guide books are also included. The collection is based on Henry-Russell Hitchcock's 'American Architectural Books' and Helen Park's 'A List of Architectural Books Available in America before the Revolution.' The microfilm edition follows the same sequence as the listing in the Hitchcock bibliography, which is alphabetical by author and then by title"--The Library of Congress Guide to the Microform Collections in the Humanities and Social Sciences Division, online version.
