Thanks to Mike Keller for passing on the address of the pre-publication
draft of "Long-Lived Digital Data Collections: Enabling Research and
Education in the 21st Century": 
<http://www.nsf.gov/nsb/documents/2005/LLDDC_report.pdf>

Something for us all to look at carefully as we think about the NSF's
grant opportunities, and their interest in cyber-infrastructure and
digital curation of collections.
