Thanks, Daniel. Konrath actually seems to be offering electronic versions of his books for free. I doubt this will work. People are fickle. They don't attach much value to books in the first place. And some (like me) may like to read in bed.
I had a much better idea this morning (my mind is amazing early in the morning). Since ephemeral itrems, such as movies and music videos and games, sell like hotcakes at high prices, and since we sell few books because everybody passes them around, donates them, resells them, or even leaves them for another reader in airports, I propose that we print all paperbacks in disappearing ink and charge double the current price for hardcovers (which will have permanent ink).
