How much do I love this book? Enough to own five copies of it juuuust in case something happens to the other four. I'm serious. It is an exhaustive, indispensable overview of 20th century comic books and the only one of its kind, to my knowledge. Sure, there are about a million books on the history of comics, but none that I know of that summarize and review everything they possibly can. And even if I don't agree with every review (some of these reviewers get downright snarky), it's still a treasure.
