“The most important source for Swiss foreign policy is the series Diplomatische Dokumente der Schweiz […]. The spread offered is impressive. The series naturally concentrates on Switzerland’s relations with the major powers, but care has been taken to include documents relating to other areas of Swiss foreign policy, so as to provide a flavour of Switzerland’s diplomatic activities as a whole. […] Documents Diplomatiques Suisses should be the first port of call for any serious research into Swiss diplomacy.”
