The book "Liber Amicorum in Memory of Sergio Ortino" is covering Globalization, Technologies and Constitutional Theory, Supranational Integration, Federalism and Minorities, Territorial and Cultural Diversity Management. Colleagues, alumni and friends of Professor Ortino tried to trace his research approach looking into new fields explaining legal phenomena. The essays collected in the book look beyond the traditional academic horizon which was too tight and narrow for Professor Ortino's innate search for new challenges, new disciplines and cross-disciplinary inputs. This ample look was always important for Professor Ortino in order to deepen the knowledge in fields that are essential to better understand the most profound reasons of legal phenomena and their evolution. This is why he could explain legal developments long before others. All his work, especially in the last twenty years of his extraordinary career, shows how foresighted he was in his research. He wrote about globalization long before this fundamental issue became "fashionable" and analyzed by legal scholars. All articles in this book are dedicated to exploring new fields, to investigating the relationship between legal phenomena and economics, anthropology, history, and trends of legal development, identifying areas where research will be needed in future. Professor Ortino's curiosity about Asia and especially China, and his critical view on the evolution of the European Union are just two examples which his colleagues, his alumni and friends have focused on in this commemorative publication.
