Query: better get it from the library first

Take the five books and make them into one book listing just about anything you can imagine(from spells to desciptions of every single person mentioned) and you have the "Muggle's guide". I was very disappointed because there was hardly anything new. Background information seemed to be mostly quoted from the official J.K. Rowling website-which existence was the only new information I got out of the whole book.(and you can look it up there online firsthand).I was glad, I got it from the library and didn't spend any money on it.Better and more entertaining is "the magical world of Harry Potter"-where you can find good research of the meaning of latin and greek words used and connection to J.K.'s personal experience like the dementors are representing depression.
