Was messing around in creative and designed a simple (and functional) little library!

Place a lectern facing backwards to which way you want the books to be accessible, then simply place a chiseled bookshelf on top!

Works as a good way to publicly exchange enchanted books on an SMP, or simply use it for decoration in builds.

Because of how simple it is, it can be easily personalized to fit the aesthetic of the surroundings (some examples shown in images 3 & 4).

Enjoy!
