This is now a critical issue in our society, as The Independent reported at the weekend (see here). In 'Thirteen Ways of Looking at ... Digital Preservation', Lavoie and Dempsey look at some of the issues involved and conclude:
Preserving our digital heritage is more than just a technical process of perpetuating digital signals over long periods of time. It is also a social and cultural process, in the sense of selecting what materials should be preserved, and in what form; it is an economic process, in the sense of matching limited means with ambitious objectives; it is a legal process, in the sense of defining what rights and privileges are needed to support maintenance of a permanent scholarly and cultural record. It is a question of responsibilities and incentives, and of articulating and organizing new forms of curatorial practice. And perhaps most importantly, it is an ongoing, long-term commitment, often shared, and cooperatively met, by many stakeholders.As experience in managing the long-term stewardship of digital materials accumulates, there will likely be even more ways we will need to look at digital preservation in the course of building digital information environments that endure over time. But this should come as no surprise: after all, Wallace Stevens found at least thirteen ways of looking at a blackbird.
