Chris Rusbridge, Director of the Digital Curation Centre, offers a "jaundiced" look at the following digital preservation truisms:
1. Digital preservation is very expensive [because]
2. File formats become obsolete very rapidly [which means that]
3. Interventions must occur frequently, ensuring that continuing costs remain high.
4. Digital preservation repositories should have very long timescale aspirations,
5. 'Internet-age' expectations are such that the preserved object must be easily and instantly accessible in the format de jour, and
6. the preserved object must be faithful to the original in all respects.
