Does PEMdata have special features for museums and libraries?
Yes. PEMdata incorporates graphs and statistics of IPI’s Preservation Metrics, a set of algorithms that process temperature and humidity data into numerical estimates of deterioration risks that threaten museum and library collections. The metrics relate to specific types of decay, characterizing the risk of mold growth, the rate of spontaneous chemical change in organic material (what might be called ‘natural aging rate’), and the mechanical risks posed by excessive dryness, dampness, and dimensional change in water-absorbing materials such as wood and paper.
