You've been watching the Summer Olympics for a week now, but what do you really know about the games? These volumes can fill you in:
The Complete Book of the Olympics, by David Wallechinsky (Aurum Press, 1,171 pages, $24.95), is the go-to book for sportswriters, Olympi-philes and barten-ders who need to settle bets. It has results for every summer Olympic final since 1896, trivia and medals tables. Guaranteed to make anyone into a certified ring head.
The Naked Olympics, by Tony Perrottet (Random House, 240 pages, $12.95). The author is a contributor to Outside, the unofficial magazine of the fresh-air set. Naked is breezy and irreverent, but nonetheless a wonderful look at an ancient pagan athletic contest that had as much corruption, debauchery and commercialization as the modern version.
