Excellent, a complex voting system! If we consult SCOTUS, the right-wing books will win.
I was thinking that some form of vote would be the best way to select books. My plan was simpler in that we would just compile a list of all suggestions and then read the one that gets the most votes. Of course, your 50% rule would be invaluable if we were to get a LOT of suggestions!
