PUBLIC ADMINISTRATION is one of the most widely adopted books for both undergraduate and graduate levels. The basis of the appeal is the three part framework of management, politics, and the law. Its theme is that all three perspectives are central to public administration, and that ignoring one or another leads to failures in both the practice of and in academic treatments of the field. This edition continues to refer to these three perspectives, but it divides management into two subsets: traditional and "the new public management".
