ABSTRACT
Digital preservation can be viewed as a set of strategies or methods used for preserving information in a certain format and also as a means for preserving information using digital systems. In the first usage, digital preservation is one aspect of preservation writ large, a companion to preservation practices for paper, film, and all the other media of art and expression that libraries collect. In the second usage, digital preservation is closely linked to digitization, the reformatting processes used to create digital surrogates for works that were issued in various nondigital formats. Most professional bodies are careful to make a distinction between digitization as a method of reformatting, and digital preservation, the ensuing process and relevant technologies for keeping the resulting digital content viable over time.
