Enchanted Books Should have unique side effects based on their enchantment.

So. When Antvenom posted the video about Minecraft weird facts. One of those facts is that you can use a silk touch book to grab things. You don't need a primary item. So, maybe other books should do other unique stuff. Like the efficiency book can break stuff faster, sharpness book can do more damage without a primary item, holding a respiration book can allow you to have extended water breathing until you switch to another slot, and so much more.
