In response to Carole DeFord's request for information on controlling
relative humidity in exhibit cases, the Canadian Conservation Institute
has published a Technical Bulletin on Silica Gel that explains the use
of this buffering agent to help control relative humidity in enclosed
spaces. It is Technical Bulletin 10, by Raymond Lafontaine, and it is
free for the asking from

Newer forms of silica gel in sheets and cassettes are easy to use. Made
by "Art-Sorb", they are available from many of the conservation
suppliers.
