I guess you could use OCR and object detection to identify books from their spines and link to Google Books or Goodreads.
Google has a patent on doing just that: https://patents.google.com/patent/US20150371085A1/en

(On another note, I have felt for awhile Patents, and Trademarks, should be tied to income, and number of patents applied for. A poor person, like myself, pays just as much as Google for a patent. Crazy? I would like to see patent fees on a graduated scale. Companies that spit out patents daily would be charged much more for every patent. For instance, Google's first patent would be $1000. After 10 the price is 1 million per patent. After 20 the price per patent is 100 million.)
