I do it all the time. I take the poor book to work, slice it's spine off with the hydraulic cutter and then feed it through my Fujitsu Scansnap. The whole process take about 15 minutes for a reasonable sized book. The software that came with the scanner makes it into a searchable PDF automatically. It's a bit ..ahh.. destructive for some people's taste but I figure by sacrificing the paper copy, I can keep the electronic one with me for a lot longer.
