For more than five decades, pioneering researcher Dorothy Seymour Mills has studied and written about baseball's past. With this groundbreaking book, she turns her attention to the historians, stat hounds, and many thousands of not-so-casual fans whose fascination with the game and its history, like her own, defies easy explanation. As Mills demonstrates, baseball elicits a passion--and inspires a slightly off-kilter, obsessive behavior--that is only slightly less interesting than the people who indulge it.
