Given that context, PERSONIUS described the College Library Access and Storage System (CLASS) Project, a library preservation project, primarily, and what has been accomplished. Directly funded by the Commission on Preservation and Access and by the Xerox Corporation, which has provided a significant amount of hardware, the CLASS Project has been working with a development team at Xerox to develop a software application tailored to library preservation requirements. Within Cornell, participants in the project have been working jointly with both library and information technologies. The focus of the project has been on reformatting and saving books that are in brittle condition. PERSONIUS showed Workshop participants a brittle book, and described how such books were the result of developments in papermaking around the beginning of the Industrial Revolution. The papermaking process was changed so that a significant amount of acid was introduced into the actual paper itself, which deteriorates as it sits on library shelves. One of the advantages for technology and for the CLASS Project is that the information in brittle books is mostly out of copyright and thus offers an opportunity to work with material that requires library preservation, and to create and work on an infrastructure to save the material. Acknowledging the familiarity of those working in preservation with this information, PERSONIUS noted that several things are being done: the primary preservation technology used today is photocopying of brittle material. Saving the intellectual content of the material is the main goal. With microfilm copy, the intellectual content is preserved on the assumption that in the future the image can be reformatted in any other way that then exists.
