This four volume set includes 373 entries on leadership theory, practice, and effects. About 150 of the entries are biographies. What stands out most about this work are the primary source documents you’ll find in it. About 300 sidebars reprint speeches, quotes and texts ranging from Aristotle on Authority to the Body Shop’s Values Mission statement. Appendix 1 reprints presidential speeches on foreign policy and war. Appendix 2 reprints a few sacred texts relevant to leadership.
The finding aids could be better; the index appears in Volume 4 alone and the lists of entries and sidebars do not include page numbers. So try browsing it.
