mooing_cowmilk | 1.20 Auto Book Sorting Using Chiseled Bookshelves Minecraft Java @mooing_cowmilk | Uploaded 1 year ago | Updated 1 minute ago
@RaysWorks video inspired me to improve the design. Reduced resources to build it along with reducing the 5x4x3 to a 5x2x3, cutting the size in half.

Minecraft 1.20 update snapshot 22w44a comes with new hopper chiseled bookshelves. Used to make auto book sorter with redstone and hoppers (totally didn't copy paste that line from somewhere.)
