Despite differences, some lessons from traditional preservation are transferable to the digital environment. In order 70-294 to avoid commitments that far exceed available resources and costly rescue and restoration efforts, preservation must become an integral part of the planning, design, and resource allocation for digital libraries and archives. Integration of preservation requirements and methods with access and maintenance systems is essential to fully and efficiently support the processes of migration, regeneration, and documentation of the life of digital objects. Planning for preservation must become an integral part of the design and management of digital libraries and archives. If left as an afterthought, there is little reason to believe that long-term preservation of digital 70-431 information will be any more affordable than preservation of conventional formats has been.
In closing, I would like to mention three issues that I discussed only in passing. One concern is the question of scale and scalability. The preservation community has at its disposal a variety of tactics for digital preservation that appear to work effectively for certain types of materials in certain restricted 70-536 environments, but we have not yet developed solutions that are scalable to the general problem of digital preservation. This is not to suggest that there is or should be a single solution to digital preservation.
