In a short piece at silicon.com “futurist” Peter Cochrane talks about a potential business idea that I’m surprised doesn’t already exist: digitizing personal book collections. As I’ve said in the past, I support the various book digitization efforts from Google and others for these projects’ potential to make the sharing of knowledge easier, not because I want to read all my books (for free or otherwise) from my computer. However, I am intrigued by the option of digitizing at least some of the books I own – perhaps books I’ve read and don’t intend to read in full again. It would be nice to have searchable, digital copies of these books to refer back to, but there are some books that I could never trade in for digital doppelgangers.
