Kevin, We are exploring similar issues at the Archives of Traditional Music as part of the Sound Directions project. A few resources I have recently found helpful: 1. IASA TC-04, which you may know about, contains high-level digital mass storage principles plus specfic information on various storage options. 2. The PrestoSpace project website has tutorials on storage and on media migration at http://prestospace-sam.ssl.co.uk/index.html 3. Two digital library-oriented articles that discuss data integrity issues, modeling threats, etc. The first comes out of the LOCKSS initiative which may not be appropriate for storing audio, but the basic ideas are important. Requirements for Digital Preservation Systems A Bottom-Up Approach http://www.dlib.org/dlib/november05/rosenthal/11rosenthal.html A Fresh Look at the Reliability of Long-term Digital Storage (technical report, work in progress 08/05) http://www.arxiv.org/abs/cs.DL/0508130 I'd be happy to talk further privately to compare notes if useful.

My belief is that >>organizations have turned over much too much power to IT departments - just because no one else >>understands the technology. IT too often tells organizational management what they have to do >>rather than the other way around." You capture perfectly my concern. It is those "high standards for data integrity" that I am trying to identify best practices for so that I can steer the conversation with our IT staff a little better than I am presently able to. I am confident we have a good backup plan, S-DLT copies separated geographically (although the archival data is not treated any differently than the corporate data), a high quality server infrastucture with clean power and fire suppression. But, it is what I don't know, how to confirm the integrity of data through all steps of ingest, preservation and access, that I am most concerned about. OAIS is a great "high level" approach which we are looking into but, it is not meant to address technical issues on the level that I am trying to. Thanks again everyone. Kevin
