"Burkhard and I are from the same town in Westphalia; 10 years ago he called me out of the blue because our interests in international relations, broadly, matched. Now as then he pursues his curiosity in politics and social change beyond borders with the great fascination and dedication. Whereas many run down narrow paths, Burkhard keeps a sharp bird's eye view. It is wonderful to discuss with him. When we met first time, Burkhard kindly offered me his meticulous multi-volume Handbook on International Relations, a rich repository of addresses which are still hard to find on the web. It offered me great service when I pursued the idea of spend a social year abroad."
