I got this book to update the one I had to the 1980 Summer Games in Moscow (The 2008 Edition did that for the Summer version and it was well done). This book has a lot of errors in it. For Nordic combined, it lists the old event of 7.5 km sprint and 15 km individual even though both events changed in late 2008 to 10 km individual large hill and 10 km individual normal hill. No details provided of the Gundersen system point time differential for competitiors in the individual and team event.
There is no mention of ski cross in the freestyle skiing section which will debut at this year's Olympics.
For cross country skiing on the combined/ double pursuit, the events listed are not accurate. 1992-8 were 10 km + 15 km combined men & 5 km + 10 km combined women, both separate days. 2002 was 10 km + 10 km combined men and 5 km + 5 km combined women, same day at seperate times. Since 2006, it has been 7.5 km + 7.5 km double pursuit women and 15 km + 15 km double pursuit men, a duathlon event. No explanation given for event.
For the knowledge that Wallechinsky and Loucky have with the Olympics, this left something to be desired.
