If I didn't have to read this thing cover to cover for a lazy teacher's class, I would trash the thing now. It is full of typos and the authors' personal opinions and speculations, presented as facts. You would think that they would have the kinks worked out by the ninth edition, but one wonders why they bothered putting out a new one at all. The book is disorganized and fails to explain terms whose definitions are clearly needed by the reader. Also the entire preface was a glorifying ode to the authors, detailing how awesomely clever they are for having written it. I have seen better historical writing in Cracked articles.
