contents	Vacuum Freeze-Drying, a Method Used To Salvage Water-Damaged Archival and Library Materials: A RAMP Study with Guidelines. McCleary, John M. Archives Case Studies Costs Emergency Programs Foreign Countries Institutional Cooperation Libraries Library Materials Paper (Material) Preservation Regional Cooperation Water This Records and Archives Management Programme (RAMP) study covers the conservation of archival documents and the application of freeze-drying to the salvage of documents damaged by flood. Following an introductory discussion of the hazards of water, the study presents a broad summary of data on freeze-drying, including the behavior of water-soaked paper; the advantages of stabilization by freezing; descriptions of vacuum freeze-drying and alternate methods of drying; and a comparison of two currently used methods (1) vacuum freeze-drying by sublimation (a dry process) and (2) vacuum-drying by evaporation (a wet process). The history of freeze-drying is described; six case histories illustrating the use of vacuum chambers for the recovery of water-damaged archival and library materials are presented; and examples of the use of vacuum and freeze-drying in eight countries are summarized. Also considered are commercial sources for freezing and drying; the cost of vacuum-drying and freeze-drying; low-cost freezing and drying in an emergency; what freeze-drying will not do; and cooperative approaches to the use of freeze-drying chambers. Finally, 24 imaginary open forum questions and answers related to freeze-drying are presented, and disaster preparedness planning is discussed. The text is supplemented with two figures and two tables, and a 75-item bibliography is provided. (KM)
