The stars in this series come from Anders Hanson's design. The credit shows him as a designer at Mighty Media, Inc. Did he pitch the series to ABDO, or did they hire his design firm for the editorial team's concept (Liz Salzmann)? We'll see what I can find out.
All stock photos and art, but with unique design work on each double-page spread. A general scheme for color and backgrounds provides a consistent feel not only throughout the book, but over the whole series. With this general rule for the look, Hanson (and Mann? did she work with him on design, or did she write the words?) have done a great job providing a cohesive and interesting visual experience.
The text is informative, but not special. Simple factual sentences are either strung together in small 2-4 sentence paragraphs or stand alone as captions. Diane Craig consulted as a reading specialist, and I wonder if she was in charge of keeping vocabulary and sentence complexity low? If not, what was her role?
