Generally, catalog records for Groups of Images in High Demand describe multiple items, from which a selection must be made. The individual items in the group may or may not be represented online.
1. Determine whether the desired materials can be retrieved online.
- Select the "About this Item" tab
- Select the "Check for online items from this group" link
- Select the "Obtaining Copies" tab for any retrieved items that are of interest.
2. If the desired material cannot be retrieved online:
Select images for reproduction through one of these methods:
- Visit the Prints & Photographs Reading Room and request to view the group (general information about service in the reading room is available at: http://www.loc.gov/rr/print/info/001_ref.html). OR
- P&P reading room staff can provide up to 10 quick copies of items per calendar year (but many original items are too old or fragile to make such copies). For assistance, see our Ask a Librarian page. OR
- Hire a freelance researcher to do further selection for you (a list of researchers is available at: http://www.loc.gov/rr/print/resource/013_pic.html).

- Medium: 2 photographs (microphotographs) : wet collodion ; diam. image 1 mm. mounted under 20mm diam. cover glass on microscope slides 1 x 3 in.
- Access Advisory: Restricted access: Materials extremely fragile; Served by appointment only.
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.
-
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.
-
-
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.
-
-
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.
