Cool, idea... what if we made a reverse lookup, so you could search in the app for the book and we could show you the picture of your shelf with the book highlighted. Thoughts?
That would be a pretty cool app, at least for people who have a lot of books.
A couple of times I've resorted to taking photos of my books when I just could not find one, so that I could look in the photos on my computer (where I can enlarge them and do not have to bend over uncomfortably to see the lower shelves) to find where the book was shelved.
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.
