WETTED BOOKS -
TECH BRIEF


Depending on the paper type and binding materials, books can absorb water two -three times their original weight. The immediate physical effects of water is wide ranging from delamination of glues in the bindings to causing coated stocks to fuse to breaking down the cellulose fiber and so forth. The increased moisture content produces a nearly ideal environment for metabolically active spores to generate mold, which left uncontrolled will further add to the loss of collection materials.

To prevent or reduce mold growth damage to wetted books, they should be refrigerated or frozen as quickly as is possible. Then the drying and restoration can be co-ordinated functions. Great care is required during removal to refrigeration facilities and excessive handling should be avoided since the materials while wetted are in a severely weakened condition and can be easily tom or damaged. If possible, refrigerate and store the materials on site to reduce handling.

With planning and effort, wetted materials can be dried, separated, shaped and, if necessary , rebound for future use.  Cryobibliotheraphy is the art of the moment -bringing together technology, equipment, institutional resources and, in the final analysis, personal commitment.
