home > monitoring your library

Knowing the “climate” of your library is an important step in preventing or limiting mold outbreaks. You can do this quite simply by maintaining a record of the temperature and relative humidity of various locations within your library. This gives you an idea of what you are contending with. In addition, it provides you with a history of climate changes your collection undergoes, and provides supporting evidence if you seek funding to address mold issues in your library.
