How can mold be eliminated from a collection?
Mold is impossible to completely eliminate from any area, as mold spores are in the air at all times. However, most molds that feed on cellulosic materials such as books and manuscripts are only active when the relative humidity climbs above 65-70%. High temperatures (above 72°F) also exacerbate mold growth. When a collection experiences mold growth, it is a sign that environmental conditions are inappropriate and must be altered. Once the environment is brought back to acceptable standards (relative humidity between 50-55% and temperature 68-70°F), mold will become inactive.
