There are also no way to find where and what informations are stored in the book.

That's got some serious potential as a Macguffin of sorts. Take an evil mastermind with Eidetic Memory; he reads through the entire book (and maybe also brings in experts to peruse it so as to add their knowledge to the total), then contrives to have it left open so as to retain all the knowledge contained therein. One method of (partial) victory available to the PC's is then to find and close the book, cutting the Big Bad off from his source of knowledge.

Of course, unless there's some sort of protection against doing so, it seems like there's nothing preventing a scribe from making a mundane copy of the Book of Ignorance - pop it open, and just copy each page into a normal book. Sure, you'll forget everything you learned once you close it, but then you can just pick up your mundane copy and read through it, regaining all that knowledge without the magical mindwipe at the end.
