How do I preserve my paper collections (e.g. documents, manuscripts, drawings, prints, posters, maps)?
The most effective and economical preservation measures are preventive: proper storage, storage environment, and handling.
Take proper care when handling flat works on paper by:
- Having clean hands and a clean work area
- Keeping food and drink away
- Using pencil, not ink, to make any necessary marks or inscriptions; in addition, only make inscriptions when the paper is on a clean, hard surface, to avoid embossing the inscription into the paper, which will be visible from the other side
- Not using paper clips, other fasteners, "dog ear" folding to mark or organize leaves
- Not using rubber bands, self-adhesive tape, and/or glue on paper
Good storage significantly prolongs the preservation of paper materials and includes:
- A cool (room temperature or below), relatively dry (about 35% relative humidity), clean, and stable environment (avoid attics, basements, and other locations with high risk of leaks and environmental extremes)
- Minimal exposure to all kinds of light; no exposure to direct or intense light
- Distance from radiators and vents
- Supportive protective enclosures
- Unfolded and flat or rolled storage for oversized papers
Individual/isolated storage of acidic papers to prevent acids from migrating into the other works on paper
