1.) The Tao Jones Averages by Bennett W. Goodspeed 1984 (this is the primer before reading Jack Bogle's books). 2.) The Democratic Party: A History by Frank R. Kent 1928 (an important read of where both modern USA political parties came from). 3.) Native American Anarchism by Eunice Minette Schuster..1970 (bias is a funny thing).
