Book Description
This report provides an update of the possibilities and limitations of currently available mass deacidification methods, focusing on the major developments in research and application of the main operational systems. This study is intended primarily to support the development of a well-considered preservation policy by librarians and archivists, with a focus on the practical implications of mass deacidification rather than the technical details of the deacidification process. The study provides a brief history of the development of the technical process, a condensed description of the treatment principle, an overview of available research and test results, indicating the main advantages and disadvantages of the process, and an inventory of actual applications for five mass deacidification systems: (1) "Battelle"; (2) "Bookkeeper"; (3) "DEZ"; (4) "FMC"; and (5) "Wei T'o." Several other initiatives are also described, involving large-scale rather than mass treatment technologies, and essentially combining deacidification with strengthening of paper. The main findings are discussed within the framework of a critical evaluation of the current possibilities and limitations of mass deacidification in general. A list of contacts is provided. (Contains 86 references.) (Author/SWC)

Book Description
Library administrators, faced with the problems of acid-paper deterioration, are examining mass deacidification procedures. Mass deacidification of acidic books while they are still physically sound and not yet brittle is the most cost-effective corrective action to extend the life of the paper. There are currently at least five mass deacidification processes available or under development, so that library administrators can begin to plan for the process. A brief and nontechnical description is given of the following five techniques: (1) DEZ (diethyl zinc), a process at the pilot stage; (2) Wei T'o, a liquified gas process that is in use in at least two locations; (3) BPA, the Book Preservation Associates System, currently available in New Jersey; (4) Bookkeeper, a process under development that involves magnesium oxide; and (5) the Lithco process, in the pilot stage. A table summarizes the properties, selection requirements, cycle times, and development stages of each of these processes. Considerations of process use, such as length of time required to treat a collection, potential damage or strengthening effects, and evaluation issues are reviewed. (Contains 103 references.) (SLD)
