Now available in paperback, Harold Seymour and Dorothy Seymour Mills' Baseball: The Early Years recounts the true story of how baseball came into being and how it developed into a highly organized business and social institution.

The Early Years, traces the growth of baseball from the time of the first recorded ball game at Valley Forge during the revolution until the formation of the two present-day major leagues in 1903. By investigating previously unknown sources, the book uncovers the real story of how baseball evolved from a gentleman's amateur sport of "well-bred play followed by well-laden banquet tables" into a professional sport where big leagues operate under their own laws. Offering countless anecdotes and a wealth of new information, the authors explode many cherished myths, including the one which claims that Abner Doubleday "invented" baseball in 1839. They describe the influence of baseball on American business, manners, morals, social institutions, and even show business, as well as depicting the types of men who became the first professional ball players, club owners, and managers, including Spalding, McGraw, Comiskey, and Connie Mack.

Note: On August 2, 2010, Oxford University Press made public that it would credit Dorothy Seymour Mills as co-author of the three baseball histories previously "authored" solely by her late husband, Harold Seymour. The Seymours collaborated on Baseball: The Early Years (1960), Baseball: The Golden Age (1971) and Baseball: The People's Game (1991).
