Submitted by: Mary Why is this item important to you?: Grandparents wedding certificate, written in Swedish. Expert Advice: (Provided by Tim Salls) This marriage certificate should be treated by a conservator, preferably one who is a member of the American Institute for Conservation (AIC). There is a Find a Conservator page on the AIC website that allows you to search for a conservator by specialty and location: https://www.culturalheritage.org/about-conservation/find-a-conservator. Presumably, the discoloration seen at the bottom of the document (from the image of the Bible/Book down) is damage caused by acidity from the cardboard storage tube migrating into the document. This needs to be addressed by a conservator to prevent further damage. The multiple tears may be mechanical damage or chemical damage due to the paper quality. The tears can be mended and the paper's pH stabilized if needed. The conservator will test the inks and colors to determine if they are water-soluble before they suggest treatment options. A digital image of the marriage certificate after conservation would assist with limiting the handling of the original document. The conservator could also create an archivally sound storage enclosure for the document to provide physical support and some protection from light and physical damage.
Submitted by: Amy Expert Advice: (Provided by Tim Salls) This appears to be an albumen photograph, which was a common photographic process late 19th century into the early 20th century. The image quality seems fine. It seems like the cockling on the right side of the image is the plastic sleeve and not water damage or cockling to the photograph. If it is actually the photograph itself then that would need to be addressed by a photograph conservator. The secondary support has some foxing – mold growth. Storage in an interior closet is usually adequate particularly if temperature and relative humidity is fairly stable. Avoid handling the original photograph as much as possible. Always wash and dry your hands before handling the original photograph and handle photographs by the edges to avoid touching the emulsion. It is important to make sure the plastic used to store the photograph has passed the photograph activity test (P.A.T.) like those sold by archival vendors such as Hollinger Metal Edge, Gaylord Archival, etc. Do not store photographs in plastic made from Polyvinyl chloride (PVC). A high-quality digital image should be made of the photograph. This will allow you to make service copies so the original can be archivally stored limiting its handling and exposure to light and pollutants. A photograph conservator, preferably one who is a member of the American Institute for Conservation (AIC), could treat this object. There is a Find a Conservator page on the AIC website that allows you to search for a conservator by specialty and location: https://www.culturalheritage.org/about-conservation/find-a-conservator. There are typically a range of treatment options from stabilizing to full conservation of the object. It may be possible for a photograph conservator to remove the photo from the mount and the treat the mount for the foxing, remounting the photograph afterwards.
Submitted by: Andrea Arnold Why is this item important to you?: Civil War diary of my great, great grandfather Jefferson Whitcomb from Townsend, MA Expert Advice: (Provided by Todd Pattison) Your Civil War diary is covered in quarter sheep leather and marbled paper. The accompanying letters are machine-made, wove paper with manuscript ink notations. Condition: The cover of the diary has a lot of wear, especially the marbled paper and binder’s board underneath, and the leather looks to be deteriorating with some damage to the hinge areas; they may be starting to break. There are no images that show the page attachment or the manuscript ink notations. The paper the letters are written on has darkened but there does not seem tom be any tears or damage from the inks. Recommendations: I would encourage you get high-quality scans made of the pages of the diary and the letters. This will provide use copies that will limit handling of the originals and will also allow you to share this information with other interested parties. It will also preserve the information in case the originals are damaged or lost. The diary may need to be imaged one-up, or one page at a time, with an overhead camera to protect the fragile binding. This would allow for quality capture of the information without opening the volume more than 90 degrees, preventing stress of the sewing or page attachment. You should have the diary boxed in a custom enclosure with folders for the letters. This will keep the information together. There are several styles of custom enclosures, including cloth-covered, drop-spine boxes and phase boxes (there are several styles of phase boxes). The key to any enclosure is that it fit the volume exactly. If you measure this yourself you need to make sure that you find the largest square dimension, as the box will be square even if the volume is not, and include the thickness of the folders, which should be cut down to the size of the volume (assuming they will still be large enough to house the letters). A cloth-covered box can be made by a conservator or bookbinder while phase boxes are usually ordered from a vendor. The folders should be made from acid-free Bristol or other cardstock material that is lignin free. If the manuscript inks are damaging the paper of the diary (bleeding through the paper to the opposite side, burning the paper, or causing tears) the diary should be looked at by a conservator to determine if any treatment is necessary. There is a Find a Conservator page on the AIC website that allows you to search for a conservator by specialty and location. Handling and storage: Handling of these objects should be limited. When handling the volume or the letters, you should wash your hands with soap and water but not wear gloves. Gloves will lower the feeling in your fingers so it would be more likely that you would damage the object; cotton gloves, especially, will catch on the worn surface of the leather and boards causing further damage. You should always place volumes in a cradle so as not to stress them when handling, but particular attention needs to be paid to the handling of this volume given the condition; the boards should be opened as little as possible so as not to stress the joints. There are foam supports that are available to cradle the volume, but you can also just use clean towels or pillows. You mention that the diary is currently stored wrapped in plastic. Plastics can break down over time, which could damage the volume, and wrapping in plastic will not let the diary “breath” which can also cause it to break down more quickly. The diary and letters should be stored out of the light in an area that has temperature and humidity controls. Higher temperatures and swings in relative humidity will speed up the chemical processes that are breaking down this object. A protective enclosure is strongly suggested as this will protect these items from light damage as well as from dust and further wear.
