Each of these volumes narrow down the topics, and contain multiple illustrations, timelines, charts, or text boxes. Although written by several authors, all follow the same format and style that creates a series that is engaging, colorful, interesting, and informative. Students will appreciate the quick facts as well as longer passages of more intensive information. The books reference new research as well as older documented facts, but they are woven together in a page-turner style that can be used by several different reading and maturity levels.
