This book is a work of pure madness, and merely examining it can make you experience hallucinations, like the tome making faces at you, calling you names or trying to bite off your fingers. This bandage? There is far too much sharp stuff around the lab! Anyway, the book seems to cover all sorts of weirdness, like summoning demons, raising the dead, and traveling to other planes of existence. Understanding it, however, seems a hopeless task, at least if you value your mind. I have another idea, though: with enough command of the book's language, and help of hallucinogenic drugs, we can add some extra pages to it. It seems such edits have been made several times already, now that I think about it.
