1. From the copious American literature on International Relations the following may be mentioned: Steve Smith, International Relations: British and American Perspectives, London, New York, 1985;
2. T. Taylor (ed.), Approaches and Theory in International Relations, London, 1978;
3. L. Jensen, Explaining Foreign Policy, Englewood Cliffs, NJ, 1982;
4. W. C. Olson, D. S. McLellan and F. A. Sondermann (eds), The Theory and Practice of International Politics: A Framework for Analysis, 4th edn, Englewood Cliffs, NJ, 1967.
5. On the plurality of approaches and the impossibility of achieving a unified analysis in this discipline, see K. J. Holsti, The Dividing Discipline: Hegemony and Diversity in International Theory, Boston, London, 1985. See also the textbook quoted in note 22. German handbooks on International Relations are mostly based on translations of Anglo-Saxon contributions and will therefore not be quoted.
