The European Yearbook promotes the scientific study of nineteen European supranational organisations and the OECD. The series offers a detailed survey of the history, structure and yearly activities of each organisation and an up-to-date overview of the member states of each organisation. This special anniversary volume celebrates 60 years of publication of the Yearbook, and its contents differs from that of the regular volumes therefore. It offers a selection of the most important articles, dealing with European cooperation and integration, to appear in the Yearbook during its 60 years of publication. These are of particular interest not only because they provide a unique historical snapshot of the many successes (and occasional failures) in the field of European integration but also because they discuss the ideals and aims that lay behind these efforts, many of which still resonate today as Europe confronts questions about its political destiny and ideal shape. This volume contains articles in English and French.
