Saving Books and Getting Books!

[Major Mario]

Just found one little problem: Some villagers can buy written books with emeralds. As far as I checked, there is no limit to how much books you can check out, potentially creating an infinite resource if a player finds a villager that buys books.

Mhmm. One day I kept selling Remi's Rulebook and got about 5 emeralds.

Thanks Remi.
