There was a bookshop around the corner which had a lady sitting in the corner and tens of thousands of second hand books everywhere, on shelves, in piles, room after room of these books. I wondered if there was a way to sell them online. I thought maybe it would be possible to photograph a bookshelf, and some sort of program could identify each book from its spine and find its ISBN and automatically list it for sale online. Then if it sold, it would be referenced back to the photo so it could be easily found even without an indexing system. I still wonder if the current tech is good enough to do that. Sadly the shop closed recently and its all gone.
