Subject: Storage cases with environmental control
Don't overlook the obvious alternative: constructing a wall and installing a door to create a small, environmentally controllable space. As the University Archivist and Records Manager at Appalachian State University in Boone, NC, from 1986 to 1992, I installed two 5,000 BTU air conditioners in the kind of space noted above, along with a dehumidifier and a humidifier. The latter was actually never needed, although I had originally suspected that the winters would be dry enough to require one. The dehumidifier should be connected with a hose to an outside window so that drainage can be automatic. Through this kind of admittedly jury-rigged operation, I maintained temperatures of 70-73 and an RH which varied from 40 to 50 percent, the latter figure occurring in the summer. The latter also sounds high, but I have been told by archivists in the business much longer than I have been that regardless of system, it is extremely difficult to achieve an RH of lower than 40 percent in the South, in the summer. The space I have described was about 30' by 30'. Ed Southern N.C.
