I'd like to see them provide options for doing other interesting things with the books they identify besides finding e-book versions of them.<p>For instance, I'd love something that would let me photograph my bookshelves and then it mails me a list of my books with LOC or Dewey numbers attached. I started making labels with LOC numbers for me books to make it easier to file them, but it was a pain in the ass to look up the numbers.
