This in-depth treatment of the organization and operation of the All-American Girls Professional Baseball League draws on primary documents from league owner Arthur Meyerhoff and others for a unique perspective inside the AAGPBL. The study begins with a brief history of women's softball, an important precursor to, and talent pool for, women's professional baseball. Next the book investigates league administration and organization as well as publicity and promotion. Later chapters cover team administrative structures, managers, chaperones, player backgrounds, and league policies. Finally, discussion focuses on the activities of the AAGPBL Players' Association from 1980 onward. Informed by many years of research and insights from former players, this exhaustive history contains 149 photographs.
