Kotter (leadership, Harvard Business School) offers an assessment of the real work of leaders, in this collection of articles first written between 1979 and 1997. The articles deal with challenges in managerial work and what differentiates effective from ineffective responses to these challenges, and they examine issues of leadership and change, coping with dependence, and webs of interaction. In a new introduction he reflects on themes that have developed throughout his work. Annotation c. Book News, Inc., Portland, OR (booknews.com)
