Abstract: Starting from a definition of the digital preservation, as well as from advantages and disadvan-tages of the document digitization, the author stresses that the issue is not whether the libraries can deliver digital information but rather how long and to what extent they will be able to provide the information their users want. Besides the problems related to the document preser-vation and to the information access, the strategies such as refreshing, migration, emulation, computer museums, transfer data on the microfilm, are considered. The new-est techniques utilize standards and metadata: a model of an Open Archival Information System as well as meta-data, which has proven to be an ideal solution to the problem of long-term preservation and access, are presen-ted. The author concludes that document preservation and the preservation of the information contained within the document are two different aspects of the same issue, and that the primary strength of computers is access to information, not the preservation of information
