4. Evolution of Environmental Monitoring at Cornell • In 1985, John Dean was appointed as Conservation Librarian and so began the Preservation & Conservation Program at Cornell.

5. Evolution of Environmental Monitoring at Cornell In 1990 I was appointed as Conservation Liaison. Among my duties were the maintenance, repair and distribution of information captured by the existing hygrothermographs. High cost of upkeep includes the purchase of • Weekly charts for hygrothermographs 100/pk @ $50. • Replacement pens 2/set all hygrothermographs @ $50. • Purchase of a sling psychrometer price varies between $100-$200 depending on brand and size. • Extra wicks for the sling psychrometer 12/pk @ $20. Sling Psychrometer Weekly Charts

6. Evolution of Environmental Monitoring at Cornell Difficulties with the maintenance of hygrothermographs: • Require staff commitment to regularly change the charts and calibrate the units. • Expense of both equipment and staff time involved. Thermohygrometer Kit

7. Evolution of Environmental Monitoring at Cornell • After 2 years of struggling with staff maintenance issues, I began the process of researching the availability of electronic sensors to replace the hygrothermographs. • Based on operating costs we were able to purchase electronic dataloggers. We chose the ACR Dataloggers supplied by the Cascade Group, Oyster Bay, NY.

9. Evolution of Environmental Monitoring at Cornell • Early 1999 - Research begins to find Web based datalogger. • 1999/2000 - Prototype tested by Cornell. • Spring 2000 - Internet Dataloggers placed at Cornell. • May 19, 2000 - Announcement of availability was made on the Cons Dist List. • January 2001 - New York State Library, Archives, and Museum purchased 60 loggers from Pinnacle toward establishing a comprehensive and networked monitoring system.

13. Evolution of Environmental Monitoring at Cornell Advantages of Internet Dataloggers for libraries: • Simple installation. • No special software needed to view or save results. • Requires an ethernet jack and electrical outlet. • Limits can be set for both upper and lower temperatures and relative humidity. • Machine generated “trouble tickets” sent via Email using predetermined notification list. Email alerts are sent to predetermined personnel until unit returns to correct settings (i.e. corrective measures are made to system).
