Now, I'm as appreciative as the next obsessive-compulsive recovering-academic of the vast riches of material becoming available online, thanks to all those Google scanners crouched in the basements of libraries around the world, madly feeding books through their machines. I download obscure tomes onto my iPad and give thanks to the dual gods Gates and Jobs, singing hymns to all the lesser pantheon of geniuses. But there's nothing like a book.
