The Dodgers Encyclopedia is the definitive book on Los Angeles and Brooklyn Dodgers baseball. It traces the history of one of Major League Baseball's most successful organizations, from the misty beginnings of its predecessors in rural Brooklyn more than 140 years ago, through their formative years in the major leagues, as a member of the American Association from 1884 through 1889, to a full-fledged representative of the National League since 1890. It covers the exciting and oftenzany years in Brooklyn through 1957, as well as a long and successful sojourn in Southern California during the last half of the 20th century.
