Heritage Documentation Programs


Heritage Documentation Programs administers the Historic American Buildings Survey (HABS), the Federal Government's oldest preservation program, and its companion programs: the Historic American Engineering Record (HAER) and Historic American Landscapes Survey (HALS). Documentation produced through the programs constitutes the nation's largest archive of historic architectural, engineering, and landscape documentation. The HABS/HAER/HALS Collection is housed at the Library of Congress.
