K-Gr 2-This visually dynamic series engages kids from the covers all the way through to the end with its vibrant colors and striking images. Each page has brilliant photographs from the past opposite present-day images for comparison. In addition to contrasting then and now, each book concludes with how things have also stayed the same. The "Names to Know" section, short bios of people who made significant or interesting contributions to the covered field, is an excellent addition. The further-reading sections include a mix of websites and print resources. (c) Copyright 2011. Library Journals LLC, a wholly owned subsidiary of Media Source, Inc. No redistribution permitted.
