An Enchanted Book contains a single enchantment for players to apply to tools, weapons, or armor. These books can be found as treasure in dungeons, strongholds, and fishing, or can be created by enchanting a book on an enchantment table. Players use an anvil to transfer the enchantment from the book to an item, expending experience points. The resulting enchanted item exhibits the power or attribute of the book's stored enchantment, enhancing its capabilities or durability.
