Which Olympic sport was the first to permit professionals to compete for medals? Who holds the record for winning the most Olympic medals? When did women athletes make their first appearance at the Olympics? Ladybird's Sydney 2000 Olympic Games ($36) provides youngsters with not only answers to these questions but other fascinating factoids as well. Each of the 28 sports being contested until October 1 is accompanied by a list of winners in the last Olympics, in Atlanta, and space to fill in the names of this year's medallists. In addition, there is a pull-out world map showing at a glance where previous Games were held. Though we're halfway through the competition, it's still worth acquiring this lean compendium as a memento or for reference. For those who can't wait that long for the answers, they are: fencing, gymnast Larissa Latynina (18 medals), and 1900. Photo: AFP
