Blazing trails in such disparate worlds as major-league baseball and high fashion, the individuals profiled in the Crabtree Groundbreakers Biographies series will interest a broad audience of young researchers. Each volume follows its subject from childhood through adult achievements, including each individual's activities today. Sally Ride details the growth and impact of Sally Ride Science, an education program the astronaut started to encourage girls to enter science fields. The titles' drab formats, featuring merely serviceable black-and-white photos, are balanced by numerous direct quotes from the subjects and interesting sidebars on well-chosen subjects that add historical and cultural context to the biographies. A glossary, chronology, and suggestions for further reading, online and on the page, conclude each volume in this sturdy series.
