The archival mission presupposes stewardship, which can provide the field with a mechanism to carve a distinctive niche within automated environments. The author warns against the untutored embrace of the "cutting-edge" of new technology. Instead, he suggests the need for study and reliance on standards, as well as the adoption of a process-oriented view for preservation management to deal with rapid technological change. He discusses the effects of automation on archival theory, presents common sense guidelines, and includes a brief analysis of specific magnetic and optical storage media. He also proposes a new archival law: With each new storage medium, archivists must reexamine their theory and expect to meet new preservation challenges.
