On Thursday, Oct. 21st, the SIA held a Facebook preservation Q&A session. Here's a question that I've gotten in the past which the true preservation experts at SIA answered. You may find this information quite helpful when working with your own family photographs.
Please note: I don't consider myself an expert in preservation. I'm just a county employee in the Library system who tries her best to glean the most she can from the reliable resources available and to act upon that information in order to become a better steward of the historical materials entrusted into her care.
Linda Sue Fischer: Does anyone know how to separate pictures that are stuck together? I have several pictures, that unfortunately do [sic] to neglect, are stuck together. I can't just pull them apart without ruining them. Any suggestions?

Alex Mendoza @ Linda: depends on how they're processed. Was it processed by a lab, if yes, then get distilled water, make sure it is distilled. If you want add some Kodak Photo Flo to the water. But check the batch on a test photo and see if there is any change. They will have to get wet and then gently separate it. Stop if you can't pull them apart, continue to soak. Good Luck.

Please note: It has to be distilled water. Tap water won't do. Well water won't do. It has to be distilled water!
Celeste Wiley, the Photographs Archivist we had because of a SC SHRAB grant to work on the Lucille Hasell Culp Collection, used this technique often. Because of neglect, many of the negatives and prints in the Lucille Hasell Culp Collection were damaged. There is still much of this separation work left to do (and being on the 2nd floor with a workroom, we can now do these types of preservation tasks when we just couldn't do them before in the cramped old BDC room. Hurray!). The extent of the damage has definitely impacted the speed at which we have been able to process her collection. (Scroll down to "Finding Aids to Archival Collections, click on "Lucille Hasell Culp Collection partially processed" for the guide).
Now comes the teaser: We have big plans for making parts of the Lucille Hasell Culp Collection available online in collaboration with the SC Digital Library. (These are the same folks who helped us launch "Phosphate, Farms and Family: The Donner Collection"). As soon as the Technical Services staff finishes their cataloging work with our large format maps, we can use the workroom for our next really big, high priority project: doing the selection, metadata, and preparation work necessary to digitize "300 [images from the Lucille Hasell Culp Collection] for the 300th [anniversary of Beaufort]" digital project AKA "300 for the 300th." Details later.
