ABSTRACT
Digital imagery is revolutionizing the traditional concepts of preservation and access in libraries and archives. Preservation has been clearly defined and understood for the last twenty years by a set of widely accepted treatments. And while these treatments have provided a strong level of assurance for the perpetuity of the original or the surrogate, the result often has been a limitation placed on access. Digital imaging promises more universal access, at the cost, however, of a decline in the level of security in the preservation of the original or a reasonable surrogate.
