Environmental Monitoring

The Environmental Monitoring Program assists in maintaining proper temperature and humidity levels within the Library. Data from Environmental Monitoring provides information about deterioration rates of paper and other materials, risk of mold outbreak, and likelihood of habitation of various library pests. Initiated in 2005, the program’s first full year of data was collected in the Rare Book and Manuscript Library’s storage spaces. Shortly thereafter, monitoring efforts expanded to several key library spaces, specifically special collections spaces and the Main Stacks. In 2010, the Preservation Department further expanded the program by training staff in departmental libraries in the use of Environmental Monitoring hardware and software.

The Environmental Monitoring program uses PEM datalogging hardware and the Image Permanence Institute's data management website, eClimateNotebook.

For instructions on operating the PEM hardware and navigating the eClimateNotebook website, please consult the eClimateNotebook User Guide.
