Protecting your Valuable Books and Documents
An Introduction for Personal Collectors

General Instructions

Caring for valuable books and documents involves prevention of future deterioration as well as repair of existing damage. Problem areas include: unfavorable storage conditions, especially extremes or fluctuations in temperature and relative humidity, exposure to direct sunlight, water damage, etc. chemical deterioration of the original materials mold and insects improper or excessive handling.

Begin by improving storage conditions. Store books and papers away from direct heat or light at a constant temperature of 71 degrees or less, with a relative humidity of approximately 45 percent. Place each item in an acid-neutral or chemically inert container appropriate for its size and shape.

Remove newspaper clippings, bookmarks, or other items which have been laid into books. Remove paper clips, staples, and rubber bands from all materials. If there are signs of ink migration from illustrations or photographs bound into a book, insert acid- neutral interleaving sheets between the affected pages.

Avoid irreversible treatments. For example:

  • Do not laminate materials.
  • Do not apply conventional glue, tape, staples, or rubber bands.
  • Do not store materials in plastic that adheres to their back or surface
  • Use only products identified as acid-free or acid-neutral.

Do not store books or papers in closed wooden cabinets unless the shelves have been sealed to protect materials from acids exuded by untreated wood. Interiors of wooden book shelves should be coated with a primer and at least two coats of high quality solvent-based acrylic paint or solvent-based varnish. Some polyurethane may be used, but test first for formaldehyde content.

To reduce wear and tear from handling, make photocopies or photographs of frequently used items.

To preserve materials for future researchers, consider placing originals in an archival repository that maintains a preservation environment and document security procedures.

For other preservation questions, consult "Additional Sources of Information" below.
