Here are the Football Legends; Those who were voted into the NFL Pro Football Hall of Fame (from the charter class to 1999)

The names are linked to (an ever updated list of) books by them or about them.  So happy hunting. (note when there are no books connected with them, other book list results may appear -- these themselves may be of great interest and fascination, you never know what destiny brings into your hand.).  Highly recommended links are highlighted.
