For browsers who want a Guinness Book experience, but with a laser focus on sports, this series is clutch. Each book follows a similar formula, starting with a history of the sport and the formation of formal competition. For MLB, NBA, and NFL, the league history is followed with the backstories, best players, and lifetime stats of each individual team. Mini bios of star athletes are followed by lists of ­all-time leaders across a variety of statistical categories. The Olympics Encyclopedia for Kids starts with the history of the games, then breaks down the individual events for both summer and winter games. There’s a section dedicated to the Paralympics, as well as past events that were discontinued and memorable milestones. Each encyclopedia includes references to times when sports weren’t equitable for athletes of ­color, early and often. The bite-sized, honest history makes this an ideal add. VERDICT A first purchase.
