The permanent collection of architectural, engineering and landscape documentation at the Library of Congress consists of measured and interpretive drawings, large-format black and white and color photographs, written historical and descriptive data, and original field notes. The collection captures the American experience through approximately 40,000 recorded historic structures and sites, from American Indian cliff dwellings at Mesa Verde to space-age technology at Cape Canaveral.
You can search
the collections, and quickly find the structures you're
most interested in. The records were created for the American
public and are in the public domain; however, in some
of images may be restricted. As is the case with
recent additions to the collections, digital images may
not be available online for all records. Should you encounter
copies of part, or all, of the record may be advantageous.
