Accessing original items, as well as citing, publishing, and reproducing material, is necessary for obtaining information about the collection, restrictions, and rights of the Historic American Buildings Survey/ Historic American Engineering Record/ Historic American Landscapes Survey.

  • Rights Notice: Images produced by the U.S. Government are not known to have any limitations; however, images obtained from other sources might be subject to restrictions. Find more information at https://www.Loc.Gov/rr/print/res/114_habs.Html.

    • Obtaining Copies

    You can download it yourself if an image is being displayed. (On the site, only some images are displayed as thumbnails because you have to access larger-sized images due to rights considerations of the Library of Congress).

    Alternatively, you have the option to buy duplicates of different kinds through Library of Congress Duplication Services.

  • If a digital image is a direct reproduction from the original and there is sufficient resolution, then it is most likely made for publication purposes. The qualities of the digital image depend partially on whether it was made from an intermediate transparency or negative copy, or directly from the original. If the digital image is being displayed, the above field includes a reproduction number, starting with LC-DIG…
  • If there is information listed in the Reproduction Number field above: You can use the reproduction number to purchase a copy from Duplication Services. It will be made from the source listed in the parentheses after the number.

    To obtain a copy, please include the catalog record (“About This Item”) and reference the Call Number provided above. If you prefer a colored or shaded copy, please note that the original may have such features. In cases where only black-and-white (“b&w”) sources are mentioned, it is usually possible to purchase a high-quality colored copy of the original.

  • Your inquiry should encompass the catalog entry (“About This Item”) and reference the Call Number provided above. A high-grade duplicate can usually be obtained through Duplication Services in case there is no data specified in the Reproduction Number section above.

    • Price catalogs, contact details, and purchase documents are accessible on the Duplication Services website.

    Access to Originals

    In some cases, a surrogate image (which can be in the form of microfilm, print copy, or digital format) is often available. To determine whether you need to fill out a slip and call out the original item(s) to view, please follow the steps below in the Reading Room for Photographs and Prints.

  • Has the item been digitized? (A small thumbnail image will be visible on the left.)

  • Yes, the item is digitized. Please use the digital image in preference to requesting the original. All images can be viewed at a large size when you are in any reading room at the Library of Congress. In some cases, only thumbnail (small) images are available when you are outside the Library of Congress because the item is rights restricted or has not been evaluated for rights restrictions. As a preservation measure, we generally do not serve an original item when a digital image is available. If you have a compelling reason to see the original, consult with a reference librarian. (Sometimes, the original is simply too fragile to serve. For example, glass and film photographic negatives are particularly subject to damage. They are also easier to see online where they are presented as positive images.)
  • No, the item is not digitalized. Please proceed to number 2.

  • Do the Access Advisory or Call Number fields above indicate that a non-digital substitute exists, such as microfilm or duplicate prints?

  • Yes, another surrogate exists. Reference staff can direct you to this surrogate.
  • No, another substitute does not exist. Please proceed to number 3.
  • If you need to fill out a slip to request an item when it is served, the staff can advise you on how to do so for future reference or for appointments that require other materials on the same day or later. In many cases, the originals can be served in a few minutes. If you cannot see another surrogate or a thumbnail image in the Reading Room Photographs and Prints, please call out a slip.

    • Please contact the Reference staff in the Reading Room for Photographs and Prints by dialing 3 and 202-707-6394 at 8:30 and 5:00 to ask for assistance from Librarian A.
