Environmental Monitoring Reports

The Conservation and Preservation Unit monitors temperature and humidity conditions throughout the Main Library and our Remote Storage Facility. Monitoring activities began in the 1980s using paper-based hygrothermographs. Later on, five PEM1 units, from the Image Permanence Institute, were purchased and rotated around the library system. Over the years, data collection and retention or these units proved problematic, as well as the fact they became technologically obsolete. In 2015 over two dozen HOBO loggers were purchased from Onset Computer Corp. and were deployed throughout the Main Library (including exhibit areas), the Business Library and the Remote Storage Facility. Reports are generated using the HOBOware software and Excel. For more information on our data logger deployment and data analysis, please contact Eric Alstrom.

While the loggers individually collect data throughout the day, our reports generate daily statistics for the average temperature and relative humidity, as well as maximum and minimum readings. These are compiled into monthly reports and ultimately a yearly report. Select reports can be read below. If you need more specific data, please contact Eric Alstrom.
