Book Name / Number is Possible Levels you can get.
The enchanted book allows for many enchantments to be added to tools that under normal circumstances cannot have that enchantment. For example, no matter how many times you enchant a sword, it will never get the Unbreaking enchantment. However, you can get the unbreaking enchantment onto the sword through using the book with unbreaking on a sword in an anvil interface.
