One day, a sport that begins with the alphabet's last letter will be invented so the Guinness folks can truly claim to cover the field from A to Z. Until then, the gamut will have to run from A(rchery) to Y(achting), with extreme sports, frisbee, and even Hacky Sack nestled in. Stats-laden sports like baseball, football, and basketball get the most coverage, but if you're desperate to know the winner of the most world championships in badminton, you'll find that here. Clearly organized and graphically appealing, this 18th edition of one of sports' standard references is as much fun as it is informative, and will prove indispensable in the settling of most bar bets.
