Slightly off topic, does anyone know how to go about obtaining an API for library books or oreillly books? It's funny that my libby/overdrive app lets me checkout books but cannot do a basic functionality like sending me a notification to read at 9pm every night or open a random chapter from the book and send as notification, so that I can start reading etc I am at a loss of how to obtain initial set of books and hence need an API to my library (San Jose Public Library)
