Sue Dunlap wrote (DistList Feb.2, 1995 Instance 8:60) of her experience with freeze dried books appearing more brittle, and not opening well. We dealt with those problems here at Stanford. Stanford Libraries experienced a flood in Oct. 1978, in which over 55,000 volumes were thoroughly saturated. The Books were frozen at a local ice storage company and were freeze dried in the Sunnyvale Lockheed space chamber. Sally Buchanan headed the restoration project. She became aware of this fragility as a result of the freeze drying. We volunteers were cautioned to handle the volumes with extreme care when removing them from the shelves in the space chamber. Volumes were boxed and consequently re-shelved in a local vacant elementary school library, which served as the site for the restoration work. The volumes were distributed upright (not too snuggly packed) on the shelves and were left undisturbed for several weeks, while they re-humidified to that which was consistent with our climate. Humidifiers were used in several parts of the library to speed the process. I believe that only after rehumidifying was treatment undertaken to clean off dried mud, restore book cloth, etc. You may wish to contact Sally Buchanan (SLIS, University of Pittsburgh) for details.
