In its fourth edition, this exhaustive guide to roller coasters in the United States and Canada also provides a history of coaster evolution (from the 16th century) and a look into the future of coaster technology and design. The book lists by state or province more than 700 coasters at more than 160 amusement and theme parks. Each entry includes contact information along with summaries of each coaster's origins, features and history. There are six appendices: famous coaster designers, the longest wood and steel coasters in North America, a coaster census by state or province, a chronology of wooden roller coasters still in operation, interesting amusement park and coaster facts, and a guide to the alpine coasters at winter resorts in the U.S. and Canada.
