Football for Coaches and Players by Glenn Scobey Warner, William Henry "Lone Star" Dietz

This is a reprint of Pop Warner's long-out-of-print classic teaching guide on the rudiments of football. Not only does it cover all aspects of the game, but it includes much information about the fully-evolved single- and double-wing formations that Warner invented at the Carlisle Indian School two decades earlier. Warner's book is of interest not just to historians but also to coaches running the single-wing today.
