In my book, Creating Family Archives: A Step-by-Step Guide for Saving Your Memories for Future Generations, I discuss the techniques that archivists use to protect historical materials from the ravages of time. I find that it's also helpful to discuss what can cause damage to your archival items. Many hazards are obvious, but others may surprise non-professionals. 

Here are the major threats to papers, photographs, and other physical items:

• Improper handling, either handling the documents roughly or by having them come into contact with the natural dirt and oils in your skin

• Fluctuating or extreme temperatures

• Fluctuating or extreme relative humidity levels, especially high humidity

• High levels of or frequent exposure to light, especially ultraviolet rays.

• Pollutants such as tobacco, fireplace, or cooking smoke; dirt and dust; urban air pollution

• Proximity to highly-acidic documents that migrate like newspaper clippings

• Harmful fasteners, like metal clips or rubber bands, and adhesives

• Storage in folded, creased, or rolled conditions

• Storage in acidic containers or adhesive albums, like magnetic photo albums

• Storage or transport in positions that cause falling, bending, breakage, or pressing

• Mold, mildew, rodents, insects, and animals in general

• Lamination

• Static electricity

• Improper labeling or packaging

• Spillage of food, beverages, or other contaminants near documents

• Natural disasters such as floods, fire, and leaks

• Theft, vandalism, unwanted sale, dispersal, or disposal

Some documents are particularly susceptible to damage. Special risk materials include: 

• Newspaper clippings

• Highly-acidic papers such as telegrams, and scrapbook and photo album pages

• Charcoal, pastel, chalk, or heavily applied pencil drawings or writings

• Scrapbooks, baby books, and other mixed-media albums

• Rare published books

• Photographs

• Folded or rolled documents

• Documents with fading ink

• Ephemera, because they were created for short-term use

• Tapes, discs, and other recording media

• Digital items, especially if no backup systems exist
