The Public Service in Europe

Originally published in 1959, and using material collected from eight languages, much of which was previously unpublished, this is a genuine comparative study, not merely describing each country separately, but an analysis of the most important questions facing 20th century public administration. A substantial historical introduction traces from Roman to modern times the concept and practice of public service and brings out the underlying unity of European experience.
