Preservation strategies help keep books, archives, and artifacts from deteriorating any further. This is different from conservation where specially-trained conservators do item-level treatments and repairs. The following guidelines will assist with preserving your own family history.
Archival materials should be stored in a cool, stable environment with a relative humidity (RH) of no more than 50% (to help prevent mold growth and reduce insect activity). Archival materials should also be kept away from light whenever possible. Acid-free folders and boxes help absorb acid from paper via an alkaline buffer (calcium carbonate) and extend the life of materials. Boxes also protect archives from light damage, dust, insects, and other pests.
Some easy ways to protect your own family papers and artifacts include storing items in a steady, cooler environment (generally 68-72 degrees) with a lower RH (i.e. no bathrooms), keeping papers and artifacts in boxes, and turning the lights off when rooms aren’t being used. Do not store important materials in attics, basements, or garages as these areas are often prone to leaks, floods, and/or temperature fluctuations. If you use a storage unit, be sure to check that it is climate-controlled. Do not sure store photographs in magnetic (adhesive photo albums) or glue items into albums as they can damage materials. Be sure to monitor for insects and other pests regularly.
Proper handling is also very important. Do not have food and/or drinks near your books and papers. Wash your hands before handling materials and use nitrile gloves when handling photographic prints and negatives to help prevent fingerprints. You might also consider rotating framed family photographs on display to limit light exposure and/or use a preservation copy and safely store the original.
Digital preservation is more complicated. Generally, archivists recommend that you store digital files in three different locations, make sure your file names/identifiers are unique and well-organized, and reformat materials as old technology becomes obsolete.
