From Wired.com, come the interesting details:
...a number of reasons for wanting to preserve physical copies of works that are being digitized; for instance, a dispute could arise about the fidelity of the digital version, and only access to a copy of the original would resolve it. Kahle also told Kevin Kelly that we’ll eventually want to rescan these books at an even higher DPI, so the digital copies will be waiting when we do.[...]
Another reason for keeping a physical copy, and one that Kahle doesn’t mention, is that the problem of long-term digital storage still isn’t completely solved. The cloud as a large-scale storage medium has only recently emerged, and it’s definitely not perfect as a long-term archival medium.
Realistically, Kahle and Co. expect to preserve 10 million books, out of an estimated 100 million published. These will be packed into climate-controlled storage containers, and stored in a facility in Richmond, CA that opens this month.I've often wondered about the longterm integrity of e-books being sold today. Think about it. We have all been around long enough to see numerous hardware changes that make old media systems unusable. Remember 8-track tapes, beta video tapes, cassette tapes, 78 rpm records, LPs, etc? One only has to look at the fact that, even today, all e-books are not readable on all e-book readers. What happens when the market kills off a few of the readers? Are you prepared to repurchase e-books that are readable on the winning hardware if you are not lucky enough to bet correctly on which company will ultimately win out?
Tree-books rule. They will still be with me when all the e-readers in the world have been fried by some catastrophic event caused by Mother Nature or her idiot sons, Man.
