Subject: Good New Readings on Digital Preservation

David Rosenthal has made preprints of two important new papers 
available. One is called "Economics of Long Term Digital Storage" and 
is available at

http://www.lockss.org/locksswp/wp-content/uploads/2012/09/unesco2012.pdf

This paper extends his earlier work on the costs of long-term digital 
storage; I heard a summary of the findings at the Library of Congress 
sponsored Storage Architectures Symposium last week, and I think it's 
definitely the most sophisticated model we have to to date of these 
costs. I'm very hopeful that David will be able to join us for the 
fall CNI member meeting to present (and perhaps even update) these 
findings.

The second paper looks at LOCKSS in conjunction with various cloud 
architectures, and actually offers a great deal of insight into the 
value of clouds for digital preservation more generally. It includes 
some of the first analysis I've seen of Amazon's new Glacier 
long-term storage option as part of a digital preservation strategy. 
The paper can be found here:

Readers may also find David's blog at http://blog.dshr.org/ helpful 
for more background on these two papers, and David's work more 
broadly.

In the UK, the Joint Information Systems Committee (JISC) has 
recently made available a report titled "Curation in the Cloud" which 
describes a number of experimental projects that are underway in the 
UK to help understand how cloud technologies interact with digital 
preservation. The announcement and a pointer to the report proper can 
be found at
