Written books placed in item frames can be copied into a player's inventory by right clicking the frame.
Copied book's author's are followed by [COPY], indicating that they are not an original copy.
Copied books cannot be sold to villagers in exchange for emeralds.
Issues
Right-clicking a frame both gives a copy of the book and rotates the item inside the frame. [Minor visual - other plugins can deny rotation of frames in regions]
