Forget School Library Journal. I've had a version of this same atlas for 25 years, and when it became outdated--I looked until I found an updated version. Why? Because this Atlas has so much information, so clearly printed and accessibly arranged, that I couldn't find a comparable book (in the same size) without getting an updated version of the same thing. I just couldn't buy anything else until I found my old friend. One of the very great virtues of this book is that it's fully packed with info and doesn't weigh a ton. Great as a reading reference for light history or heavy fiction.
