The formatting of this book is appealing, a good mixture of picture, caption, text, and color.  Also, appreciated is the content, it has some “meat” to it.  Not just one or two facts per page, but some short paragraphs to read.  The younger readers will appreciate the graphic imagery and pick out some reading, and the intermediate students can read the text.  It makes this book even more valuable in a K-5 library. The expected glossary, and addition resources are in the back.  This is a facthound.com book, as well.  Recommended.
