List of imaginary books
An imaginary book or fictional book is a book which "traditionally exist only within secondary worlds" of works of fiction, where it can fulfill various functions and may "act as keystones to the structure of both the stories and the worlds in which they appear." == List of notable imaginary books == The Necronomicon in H. P. Lovecraft's books serves as a repository of recondite and evil knowledge in many of his works and the work of others. Despite the evident tongue-in-cheek origin of the book, supposedly written by the "Mad Arab Abdul al-Hazred", who was supposed to have died by being torn apart by an invisible being in an Arab marketplace in broad daylight, many have been led to believe that the book is real.
