摘要：This document attempts to present the different preservation methodologies that are currently available to the library, as well as provide an indication how these methodologies could be used to preserve digital materials. It is the goal of this document to outline the current thinking of the digital preservation branch in such a way that it is possible to decide, in close collaboration with each collecting area, which digital preservation strategies are most appropriate for each collecting area. It is also intended that this should provide a means for identifying where a collection area may require additional resources, as well as where new technologies should be acquired, or developed.
