Digital Preservation Discussion--Susan
Email from Susan 9 June 2011 outlines conundrum.  Campus will not be adding server space.  We currently rely on Campus servers to house our preservation copies of scanned materials.  We have in the neighborhood of 200GB remaining.  Susan estimates this represents about a year's worth of scanning.  We currently pay in neighborhood of $3.00 per GB to Campus IT for storage.  The Library running its own server for the purpose is not an option.  Several options for consideration outlined in email.  Individual committee members committed to research these options and return a report including pros/cons and resource requirements at next meeting to be scheduled for early fall.  We will discuss reports at that time and make recommendations.  Stephen will be requested to comment on the recommendations.  Below are the options with individual researching. 

1) JPEG 2000--Convert preservation scans from TIFF to JPEG 2000.  Estimate this would reduce storage space required to 1/3 of that required to store TIFF.  Lindsey will research this option.
2) MetaArchive--Distributed storage cooperative.  Vicki will research.  Will also contact Kelly about a LOCKSS machine that we have, but have never turned on (?).
3) Duracloud--Cloud based storage.  Heather will research. 
4) Florida Digital Archive (FDA)--Dark Archive.  Susan will research.
5) Chronopolis--Distributed storage cooperative.  Tom will research.
6) OCLC--Offsite vendor.  Susan will research.
7) Tiered approach--Not storing preservation copies of everything that is scanned.  No research necessary for this option.  If adopted would require discussion on selection criteria.
8) UMBC Data Storage Center--UMBC has built a data storage center.  Stephen will discuss with Jack Suess.
