"For thirty-three years and through three editions, Bass & Stogdill's Handbook of Leadership has been the indispensable bible for every serious student of leadership. This completely revised and updated fourth edition reflects the growth and changes in the study of leadership over the past seventeen years, with new chapters on transformational leadership, ethics, presidential leadership, and executive leadership. Throughout the Handbook, the contributions from cognitive social psychology and the social, political, communications, and administrative sciences have been expanded."--Jacket.
