Children's LiteratureThe books from "Isaac Asimov's 21st Century Library of the Universe" series are soundly written with plenty of clear scientific explanations and interesting facts, but they are not terribly exciting. Each book reads like the next, as they all progress through the history of scientific discoveries leading to what we know about the particularly celestial body today. The rigid formatting and repetitive writing is a disservice to their often-impressive content. For example, the fact that landing on the surface of Uranus is probably impossible because of its gaseous composition is relegated to an unexciting sidebar that readers may forgo. There are few photographs in this book and many of the illustrations are not particularly convincing. Scientists have little knowledge of the planet. As such, the book is thin on information and appears drawn out to fit the page requirements. 2004 (orig. 1988), Gareth Stevens Publishing, Ages 6 to 10.
