Minecraft wiki entry for Enchanted_Book, associated text: Enchanted books do not exhibit their enchantment. For example, a book with Sharpness IV as an enchantment does no more damage than an un-enchanted book, or any non-weapon item, would when used as a weapon. An exception is the Fire Aspect book which can ignite TNT and light campfires and the Mending book if the block mined can be broken by fist. ‌[Bedrock Edition only]
