The Book That Tells Everything is the name of a magic book that appears in the comic book story "The Smurfs And The Book That Tells Everything". It is mostly a book with blank pages that have nothing but the page numbers on it. The user of the book must turn to the title page where the book will speak to its user, waiting for a question to be asked. When a question is asked, the book will tell its user to go to a certain page, and the answer will magically appear on that page. However, the book only gives the answers to questions, never addressing possible consequences of following these answers. Also, the book can only answer a certain number of questions at a time before it requires rest to recharge its energies.
