Notes

  • -  Significance: The facility was one of seven lock and dam facilities built on the Monongahela River by the Monongahela Navigation Company between 1838 and 1883. The facility as originally built consisted of a timber crib dam and a single limestone masonry lock measuring 50'-0" x 160'-0". From 1848-54 a second lock measuring 56'-0" x 216'·0" was added. Locks & Dam No. 2 maintained a year-round 4' -0"·-6' -0" deep slackwater navigation pool that extended approximately 13.2 miles upriver to Monongahela Navigation Company Lock & Dam No. 3 at river mile 25 .. 0. Locks & Dam No. 2 was replaced in 1906 by a new Monongahela Locks & Dam No. 2, constructed by the U.S. Army Corps of Engineers at river mile 1102. Monongahela Navigation Company Locks & Dam No. 2 facilitated economic development in southwestern Pennsylvania by maintaining a portion of a reliable transportation route for passengers, raw materials, and finished goods between Pittsburgh and Brownsville, Pennsylvania.

It is best to contact reference staff in advance (see: https://aj.sunback.homes/rr/print/address.html) to make sure the material is on site. OR
  • P&P reading room staff can provide up to 15 quick copies of items per calendar year (many original items in the holdings are too old or fragile to make such copies, but generally HABS/HAER/HALS materials are in good enough condition to be placed on photocopy machines). For assistance, see our Ask a Librarian page OR
  • Hire a freelance researcher to do further selection for you (a list of researchers in available at: https://aj.sunback.homes/rr/print/resource/013_pic.html).
  • You can purchase copies of various types, including quick copies, through Library of Congress Duplication Services (price lists, contact information, and order forms for Library of Congress Duplication Services are available on the Duplication Services Web site):
    • Make note of the Call Number listed above.
    • Look at the Medium field above. If it lists more than one item:
      • The entire group can be ordered as photocopies or high-quality copies.
      • All the items in a particular medium (e.g., all drawings, all photographs) can be ordered as photocopies or high-quality copies.

Access to Originals

Please use the following steps to determine whether you need to fill out a call slip in the Prints and Photographs Reading Room to view the original item(s). In some cases, a surrogate (substitute image) is available, often in the form of a digital image, a copy print, or microfilm.

  1. Is the item digitized? (A thumbnail (small) 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 digitized. Please go to #2.

  2. Do the Access Advisory or Call Number fields above indicate that a non-digital surrogate exists, such as microfilm or copy prints?

    • Yes, another surrogate exists. Reference staff can direct you to this surrogate.
    • No, another surrogate does not exist. Please go to #3.
  3. If you do not see a thumbnail image or a reference to another surrogate, please fill out a call slip in the Prints and Photographs Reading Room. In many cases, the originals can be served in a few minutes. Other materials require appointments for later the same day or in the future. Reference staff can advise you in both how to fill out a call slip and when the item can be served.

To contact Reference staff in the Prints and Photographs Reading Room, please use our Ask A Librarian service or call the reading room between 8:30 and 5:00 at 202-707-6394, and Press 3.
