The Digital Curation Centre has released Preservation and Curation in Institutional Repositories.
Here's an excerpt from the announcement:
The DCC has produced a report that provides a snapshot of the state of the art of preservation and curation in an institutional repository context in early 2010, noting areas of recent and current research and development. It should be of interest principally to institutional repository managers and others concerned with the strategic planning for these services. The report begins with a brief introduction to preservation and curation, followed in chapter 3 by a summary of the current provision for these activities in EPrints, DSpace and Fedora. Some repository models and architectures relevant to preservation and curation are presented in chapter 4 and chapter 5 respectively, while a selection of preservation planning tools of possible use in a repository context are described in chapter 6. Pertinent developments in metadata are reviewed in chapter 7, while tools for working with such metadata are presented in chapter 8. Technologies that assist in performing emulation, reverse engineering and migration are described in chapter 9. The issue of identifiers for repository materials is tackled in chapter 10. A selection of guidelines and tools for auditing curatorial aspects of institutional repositories is presented in chapter 11, and a selection of tools for calculating the costs and benefits of curation is presented in chapter 12. Finally, some conclusions are drawn in chapter 13.
