A Hybrid Systems Approach to Preservation of Printed Materials

by Don Willis
November 1992

This report, prepared at the request of the Technology Assessment Advisory Committee (TAAC), is one of a series alerting the Commission on Preservation and Access and others to developments and possibilities within the context of national and international initiatives for preservation of and access to information printed on disintegrated paper and other substrates.

The paper was subjected to a pre-publication review by TAAC members, although it remains principally the work of Don Willis, Vice President, Electronic Product Development, University Microfilm International. TAAC hopes that this publication will spark additional thinking, discussion and progress regarding reformatting technologies and that it will contribute to our collective understanding of how preservation and access needs can be addressed by emerging technologies.

NOTE: Definitions of most technical terms appear in M. Stuart Lynn’s glossary, Preservation and Access Technology/The Relationship Between Digital and Other Media Conversion Processes, published by the Commission on Preservation and Access, August 1990.
