Ask HN: Could AI / visual processing sort out the local bookshop?

There's a bookshop around the corner that is stuffed to the ceiling with books. An old lady sits there all day - I'm sure they aren't online. When I go in there I look at the thousands and thousands of books and I can't helping wondering if AI/machine learning would be able to, given high resolutions photos of each bookshelf, identify the books, find them in a book database, and put them online to a second hand bookmarket like abebooks.com and then when a book is sold, be able to tell the store owner exactly where to find the book in the store. It's just a thought exercise but I wonder if this would actually work.
