America's New Cross-Country Sport
Designed to help the newcomer orient quickly to his or her first meet, this new book covers all "the basics": proper use of map and compass, the various types of meets (cross-country, score, trim, relay, night, ski, bicycling, etc.) techniques and training, clothing and equipment, plus a nutshell review of the sport's history and the details of how to run a meet and form a club.
... The authors, HANS BENGTSSON and GEORGE ATKINSON were organizers of the New England Orienteering Club. Bengtsson grew up in Sweden, where orienteering is a major national sport; Atkinson, a graduate of Springfield College, is instructor in Recreation Education at Northeastern University.
