If you want to preserve color photographs, have a photographer make black-and-white prints as backups—color film and slides have a shorter life span than black and white. Transferring photos to video is not a guarantee of longevity because videos deteriorate over time. Individual photographs and postcards should be kept in protective sleeves made of chemically inert plastics such as polyester (known by brand names such as Melinex 516 or Mylar D), polyethylene, or polypropylene. Don’t use vinyl or PVC, which can cause chemical reactions. These sleeves, which come in many sizes, will provide support, allow handling without smudging, and protect emulsions that can often flake and peel with the passage of time. Then store the photos flat and upright (not on top of each other) in buffered or metal boxes—no rubber bands or paper clips! If you want to store photos in an album, make sure the pages are made of the same inert plastics or buffered paper. Never glue the photos onto the pages; instead, use mounting corners available from photography and archival suppliers. Make sure to record information—date, place, people, events—on the back of each photograph or else future generations will have no way of knowing what they are looking at. Press lightly when writing and use archival-quality markers, pens, or pencils.
