BiblioCraft is a fairly simple mod that adds 8 new types of unique storage blocks to display a few different items. There is a bookcase that shows up to 16 books on the shelf, an Armor stand to display a full set of armor. There is also a potion shelf for up to 12 potions, a tool rack to hang 4 different tools/weapons, a general shelf that can display any 4 items, a display case for a single fancy item, and a wooden label that can display up to 3 items in small scale for tasks such as indicating what is in a chest. The newest edition includes the wooden Desk that can hold up to 9 books.
