Why digital preservation?

Graphics from digitization projects, electronic dissertations, non-textual materials, digital grey literature: an ever growing portion of library stocks consists of digital information in various formats which need to be collected, made accessible and preserved.
While the life of books made of acid-free paper is proven to be several hundred years, the question if and with what devices digital files can be accessed may arise already after a few years. Storing materials exclusively on digital data carriers will result in a loss of data to an incalculable extent.

Therefore, digital preservation (dp) as part of an overall strategy of information policy aims to preserve digital objects for future generations.
Both the UNESCO in its Charter on the Preservation of Digital Heritage (2003) and the German Network of Expertise in Long-Term Storage of Digital Resources (nestor) demand that the digital heritage be preserved and define appropriate framework conditions for this.
