The HABS/HAER Collections are one of the LC's Historical Collections for the National Digital Library.
The HABS/HAER Collections are one of the LC's Historical Collections for the National Digital Library.

A permanent collection of architectural and engineering documentation is safeguarded for you at the Library of Congress (LC). This national treasure consists of measured and interpretive drawings, large-format black and white and color photographs, written historical and descriptive data, and original field notes. The documentation captures the essence of the American experience through more than 37,000 recorded historic structures and sites, from Native American cliff dwellings at Mesa Verde to space-age technology at Cape Canaveral.

Now you can view the collections online and search our database allowing quick access to the structures you're most interested in. The records were created for the American public and are in the public domain; however, in some instances, use of images may be restricted.

HABS/HAER documents are filed in easy-to-use formats & sizes.

As is the case with recent additions to the collections, digital images may not be available online for all records. Should you encounter this, ordering copies of part, or all, of the record may be advantageous. Or, if you have questions, contact the LC Prints & Photographs Division reference staff.

Facts and figures about the HABS/HAER Collections will be updated quarterly, while the division's administrative records are available through the National Archives and Records Administration, Record Group (RG) 515.
