Minecraft/Enchanted Book
Enchanted books are items that hold enchantments for later.
Obtaining edit
There are many ways to get enchanted books. They can be bought off librarian villagers, fished up, found in chests in almost every naturally generated structure with a chest, and can even be made. To make one, just make a book and enchant it on an enchantment table.
Use edit
To use one, combine it with the item you want to enchant on an anvil.
