If you are expecting something like Guinness World Records, do not buy this book. Ripley's Believe It or Not! is not a record book, but just a book about amazing and incredible things. The book is formatted in a way that you can just flip to any page and start reading. I would recommend this book for younger audiences, as most of the book is pictures. I am skeptical to believe some of the "facts" in this book, as with prior knowledge I know some of these aren't true, and I doubt the researchers really did their research. But this book is aimed towards kids, and my children enjoyed it.
