The Historic American Buildings Survey (HABS) and the Historic American Engineering Record (HAER) collections are among the largest and most heavily used in the Prints and Photographs Division of the Library of Congress. The collections document achievements in architecture, engineering, and design in the United States and its territories through a comprehensive range of building types and engineering technologies including examples as diverse as the Pueblo of Acoma, houses, windmills, one-room schools, the Golden Gate Bridge, and buildings designed by Frank Lloyd Wright.
The Historic American Buildings Survey (HABS) and the Historic American Engineering Record (HAER) collection includes digital images of measured drawings, large-format photographs, and written histories for 10,000 historic structures and sites dating from the seventeenth to the twentieth century. These collections display building types and engineering technologies from a farmhouse to a pickle factory, from churches to the Golden Gate Bridge. New material is added monthly. A gallery of images includes 36 photographs and 18 drawings of 50 structures, one from each state in the U.S. The site is searchable by geographic location, keyword, and a subject index that is organized by structure type. For each structure, the site provides from one to ten drawings, from one to 30 photographs, and from one to 50 pages of HABS text in facsimile detailing the structure’s history, significance, and current physical condition. Useful for a specialized audience, for architectural historians, or for those looking for illustrations and examples.
