Deacidification, the reduction of acid in paper by use of the water process (the Barrows Lab at the Library of Virginia is a prime example) or with a non aqueous method (Bookkeeper is an example), is not a new idea. Recently it was described as non-viable. This statement prompted research. Does deacidification still happen? Apparently it does. Library of Congress has an ongoing contract for deacidification with the goal of deacidifying 1,250,000 titles by 2015. This is the most recent contract of several. New York University is listed as a participant with the same contractor as LC.
The MARC format allows for a note in the 583 field to report deacidification of a title. It would be helpful to retrieve many of these 583 notes to get a picture of the extent of deacidification. To date, I have only retrieved 26 titles with deacidification notes from the new LC catalog. I provided feedback about the new catalog and asked questions about proceeding with my research. I hope I can get a bigger picture of the progress and accomplishments of deacidification.
Stay tuned for an apologia!
