The Historic American Buildings Survey (HABS) and the Historic American Engineering Record (HAER) of the Library of Congress document achievements in architecture, engineering, and design in the United States and its territories through a comprehensive range of building types and engineering technologies. As of March 1998, America's built environment has been recorded through surveys containing more than 363,000 measured drawings, large-format photographs, and written histories for more than 35,000 historic structures and sites dating from the seventeenth to the twentieth century.
Rather than duplicate the efforts of the National Park Service, the California Almanac has chosen instead to provide links where they exist to this valuable resource. As of Tuesday, April 04, 2000, the collections are not yet complete. We will continue to monitor them and provide useful links as they appear.
Links to HBS/HAER pages are marked by the abbreviation (HBS/HAER).
