Minecraft wiki entry for Armor_farming, associated text: The most efficient way to get the best set of armor is to put enchanted books on armor in the anvil. You can stack up to six enchanted books on an item in survival mode, or up to 12 if you combine two books together and then put them on the armor piece. To get the best enchantments on your armor you will need to gather the enchanted books, gather the armor, and get levels and an anvil to combine them.
