Those RFP criteria have been widely adopted and are summarized below: process must be demonstrated as effective for mass deacidification. scientific soundness and safety of the process must be substantiated throughout with supporting data. process must add to the necessary alkaline reserve, treat substrates uniformly and not. The Future of Deacidification in Research Libraries • The landscape has changed –radically. –Mass Deacidification –first Library of Congress contract was volumes. –Mass Digitization –first mass digitization project announced called for digitization of over 7,, bound volumes.
COVID Resources. Reliable information about the coronavirus (COVID) is available from the World Health Organization (current situation, international travel).Numerous and frequently-updated resource results are available from this ’s WebJunction has pulled together information and resources to assist library staff as they consider how to handle coronavirus. of the program. Deacidification is generally believed to extend the life of a book by two to five times. Therefore, if paper in a new book has 50 years of useful life remaining, deacidification can extend this to to years. If paper in an old book has only 5 years of life remaining, deacidification will only extend its life 10 to 25 years.
It wood be good to have a comparison with what Google budgets for book scanning.

Types of Deacidification Processes. Deacidification processes are either aqueous (using water) or non-aqueous (not using water).
Most deacidification processes use some type of alkaline earth metal to neutralize acidity. This ingredient is carried and placed into the fibers of the acidic material through a gas or liquid carrier (Zachary7).
The Library of Congress, with strong support from the U.S. Congress, has provided leadership in the development and evaluation of mass deacidification processes. The Library's year initiative in mass deacidification began in and aims to extend the life and utility of at-risk paper-based materials in the Library of Congress.
Mass deacidification is an economic approach to stabilizing. deacidification processes. This report deals with the DEZ phase of the two year initiative.
It describes the progress achieved in this effort and recommends changes that should be considered in any future application of the DEZ process. Background: At the end of the procurement effort to obtain mass deacidification services inthe expert. pub8. Technical Considerations in Choosing Mass Deacidification Processes Sparks, Peter (5/90, 22 pp.) ISBN $ A scientific consideration of mass deacidification processes, providing background and an analysis of six technical evaluation factors: the procedures’ effectiveness, unwanted changes in materials, process engineering, extra benefits from specific processes.
Mass deacidification is a term used in Library and Information Science for one possible measure against the degradation of paper in old books (the so-called "slow fires"). The goal of the process is to increase the pH of acidic paper on a large scale.
Although acid-free paper has become more common, a large body of acidic paper still exists in books made after the s because of its cheaper. Bookkeeper Deacidification neutralizes harmful acids and greatly extends the lifespan of books and documents.
Plus, it’s safe and clean. Bookkeeper deposits a non-toxic alkaline buffer into the paper that neutralizes harmful acids. The process does not require solvents or gases that can damage inks, adhesives, paper, or binding fabrics.
And because Bookkeeper is solvent-free, no [ ]. By Norvell Jones, Former Chief, Conservation Laboratory, National Archives and Records Administration The National Archives and Records Administration is not now involved in a mass deacidification program.
At first glance, it may seem strange for us to convene a conference on deacidification when our institutional involvement in mass deacidification is observational rather. Left: Brittle book with pages detached; Right: Brittle pages separating from binding Briefly stated, the term deacidification denotes the treating of a paper-based object to neutralize its acidic content, with the objective of prolonging the object’s useful life.
As most deacidification measures also provide a reserve of alkalinity to neutralize. Mass deacidification Last updated Septem Mass deacidification is a term used in Library and Information Science for one possible measure against the degradation of paper in old books (the so-called "slow fires").
The goal of the process is to increase the pH of acidic paper on a large scale. Although acid-free paper has become more common, a large body of acidic paper still exists.
Effect of Mass Deacidification on Protein Materials. The last phase of the research project involves the evaluation of the effect of mass deacidification on protein materials. Protein breaks down easily under alkaline conditions and so there is much concern over the deposition of an alkaline reserve into book components which contain proteins.
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.
Ageing behaviour is an important aspect of the appraisal of mass deacidification using aminosilanes. The results of the AR determinations after the three different ageing processes are shown in Table paper treated by ATES seemed to present approximately the same fair resistance to the hydrolytic-driven types of ageing (columns 3 and 4, Table 2).

Mass deacidification is one of a range of strategies library directors must consider to address a problem that affects, by one estimate, 80 million books in North American research libraries.'
