This document presents a comprehensive glossary of terms which are associated with document preservation technologies; there is a particular emphasis on the technologies of media conversion and the use of digital computer technologies. The glossary also includes technologies associated with access to such preserved materials. A document such as this is designed to serve a duality of purposes: first, to provide clarity to a growing technical terminology, and second, to examine the impact of digital technologies on libraries. The overall structure of the glossary is organized by three major concepts: (1) the original document (medium, format, periodicity, properties, condition, content); (2) the selection process (by title, category, bibliography, use, condition, scholarly advisory committee, conspectus); and (3) the preserved copy (technologies of preservation and media conversion, capture, storage, access methodology, distribution, presentation). A subject index and 12 references are provided. (MAB)
