Actually I think such a book is already in print...in Norwegian.
A Norwegian orienteer houseguest last week gave me a copy of a beautiful book called
O-BOKA-2005 Norsk og internasjonal orienteringsidrett sesongen 2005 Measuring a big 8-1/2"x12" it is filled with hundreds of color photos, color maps, tables and results from major events in Norway, and around the world during 2005.
The color photos are excellent, and show off the relatively younger age groups that orienteer internationally...i.e. lots of sweaty babe shots. I can't think of anything more motivating for a younger U.S. orienteer, tired of seeing pictures glorifying haggard old people, than a copy of this book.
The maps are very detailed and complete, showing the 3 top men and women's routes, and their splits on each leg. So even tho I don't read Norwegian, I can spend hours in an armchair trying to figure out why one leg was so much faster than another.
According to Christian, the book sells for about $50US in Norway <
