A '''knowledge book''' is a utility item that reveals available [[crafting]] recipes to the player when {{control|used|use}}.

== Obtaining ==
Knowledge books can be obtained only by using [[commands]], as it is not found in the [[creative]] inventory; therefore, it is impossible to obtain in other modes such as [[survival]] and [[adventure]] except with commands.

For example, to give oneself a knowledge book that reveals the recipes for [[bucket]]s and [[flower pot]]s, use: {{cmd|1=<nowiki>give @s minecraft:knowledge_book[minecraft:recipes=["minecraft:bucket","minecraft:flower_pot"]]</nowiki>}}.

== Usage ==
Knowledge books are used to reveal recipes to the player who uses it, by adding it to their [[recipe book]]. Using a knowledge book consumes it, removing it from the player's inventory.

Knowledge books are especially useful to mapmakers in conjunction with {{cmd|gamerule doLimitedCrafting true}}, because then any item is craftable only if its recipe is unlocked first.
