Preservation Week 2013

Cornell University Library Conservation celebrated Preservation Week 2013 by posting a preservation tip on our Facebook page each day.

Here is a summary of the week’s tips.

Tip #1: Do not store your books and documents in the basement.  Sustained humidity above 70% will promote mold growth. For more information on assessing the temperature and humidity of your library environment check out the dew point calculator at the Image Permanence Institute web site.

Tip #2: Archival enclosures will preserve your family collections for generations to come. Check  preservation supply companies  for safe paper and plastic enclosures for documents and photographs. The Northeast Document Conservation Center has compiled useful information in their Storage Methods and Handling Practices preservation leaflet.

Archival folders and boxes protect photos and documents.

Preservation Week tip #3: Protect your library materials from light. Exposure to light can cause cloth and leather to discolor, photographs to fade, and varnishes to yellow. The Library of Congress has information about the lighting of library materials.

Preservation Week Tip #4: Do not use office supplies with your family treasures. Pressure sensitive tape and paper clips will stain and damage paper and photographs. Post-it notes leave a sticky residue.

Preservation Week Tip #5: Keep food and drink away from library materials and family treasures. Food residues attract insects, mold and other predators. Food and drink stains are permanent.
