Collaboratively compiled and deftly co-edited by Douglas Booth and Holly Thorpe (both of whom are faculty members with the Department of Sports and Leisure Studies at the University of Waikato, New Zealand), the "Berkshire Encyclopedia Of Extreme Sports" is impressively organized and includes 42 articles on contemporary extreme sports by knowledgeable contributors including scholars and athletes. There are also 19 essays dealing with the social, political, and media context of extreme sports, 35 biographies of leading extreme sports athletes, as well as 73 sidebars (many written by athletes recounting their own exploits). The "Berkshire Encyclopedia Of Extreme Sports" is enhanced with the inclusion of a comprehensive index, extensive cross-references, and a topical reader's guide. In addition to being an essential acquisition for both school and community library Sports & Athletics reference collections, the "Berkshire Encyclopedia Of Extreme Sports" is especially recommended for students and non-specialist readers of any age who have an interest in any or all of those sports and athletic activities which have come to be called 'extreme'.
