Preservation of Electronic Scholarly Publishing: An Analysis of Three Approaches

Scholars publish in journals to preserve their work and to make sure that it is available for current and future researchers. More and more of this publishing is done in electronic format. Libraries, the institutions that have traditionally overseen the preservation of print publications, are now struggling with the preservation of digital scholarly works. Issues of technical and licensing constraints and economic concerns must be addressed. This paper analyzes three approaches to the preservation and archiving of electronic scholarly publishing. A set of basic criteria is applied to dark archives, moving wall, and caching approaches.
