Amicus . 2011. PLB $28.50. Gr 4-6 Gifford prepares readers for the 2012 Summer Olympics by featuring groups of sporting events and the rules and regulations for each one. He does an admirable job of explaining the scoring for such competitions as diving and gymnastics. Readers will learn about new events, such as the Omnium, which consists of six different races for track cyclists. "Olympic Oops" text boxes highlight funny mistakes, while others point out former superstars and records. In every book, the final chapter on "Gold Medal Greats" contains brief biographical sketches about star athletes. Crisp, full-color action photos vary in size and add information as well as variety to each page. If Olympic books were in demand during the last games, this series should circulate well.
