Review title: You don't have to buy this.
Product review: I came here to write a review for this book, and found that a reviewer below, "A reader", had already written what I was going to write. This book provides a reader with no information, but with long lists of websites to look at. You can access those websites most often just wasting time (like "A reader" already said). Using search engines like Google/Yahoo is much better than thumbing through this book.
