Transforming Libraries Through Digital Preservation

I would like to step back from the close technical detail of the various and excellent tutorials that have been presented and to fill in some details of other important dimensions of digital preservation. I want to put digital preservation in the larger context of changes in scholarly communication and to argue that preservation is at the center of those changes and that preservationists should not shrink from but rather aspire to the high purpose of that central transforming role. Then I want to turn to some of the economic and political aspects of this emerging transformation.
