Digital Preservation in a National Context: Questions and Views of an Outsider. H.M. Gladney. D-Lib Magazine. January/February 2007.
“A solution is known in principle for every difficult technical problem of digital preservation.” Non-technical preservation challenges are greater than the technical challenges. Preservation is only a small part of “archiving”. Some information may disappear, including some that was supposed to be permanent. “Curators need to learn to live with not knowing for sure that they have succeeded.” A preservation solution would incorporate methods for:
- Ensuring that each saved bit-string survives as long as somebody might want it;
- Ensuring that readers can find and use any preserved object as its producers intended;
- Providing evidence with which readers can judge information authenticity;
- Integrating preservation support seamlessly with current information services; and

64 DVDs on a disc: holographic storage to ship. Lucas Mearian. Computerworld. February 12, 2007.
InPhase Technologies will begin shipping the industry's first holographic disc drive in July. The holographic disc will hold 300GB of uncompressed data and 300GB of error correction and data redundancy. It is a write once disc intended for the archival market and has a 50 year expected lifespan. To a server, the disc will look like a drive with drag and drop capability. The holographic drive will cost $18,000 and the discs will cost $180 each. The company expects to have a rewritable disc in 2008, and a 1.6TB disc by 2010. It also plans to have a holographic jukebox in 2008 with a capacity of 675TB.
