From the How It Happens series, this book shows the making, packaging, and distribution of frozen pizza. A typical double-page spread includes two large, color photos and several lines of text discussing matters such as the ingredients needed and the nightly cleaning of the equipment. Since frozen pizzas are a staple for many families, the topic is well chosen. The text explains the processes clearly, though the pictures sometimes look fuzzy. A short glossary and two recommended Web sites are appended. Another title in this serviceable series is How It Happens at the Motorcycle Plant (2007).

Gr 3-4-These titles provide step-by-step descriptions of how an item makes the journey from individual parts to a complete whole. Each spread includes large color photographs and a few sentences, resulting in a clean, engaging layout. Descriptions occasionally feel uneven. Motorcycles are particularly complicated machines with many parts, and the explanations sometimes make assumptions about previous knowledge of them. It's unfortunate that there's no simple diagram with labeled parts. There is no discussion of how a pizza crust is made or its ingredients, despite a thorough breakdown of tomato sauce. These books are similar in audience appeal and format to the "Made in the USA" series (Gale), but are not repetitive of specific subjects. While not essential, they would be acceptable additions to most collections.-Jody Kopple, Shady Hill School, Cambridge, MA Copyright 2007 Reed Business Information.
