This book is part of the Italian Americanists' interest in how Europe has contributed to US modern society and culture in the context of the interpretative innovations launched since the 1970s that have revolutionized the narrative of the American past. This book aims to be such a survey by focusing on historical studies of social stratification, international relations, consumer cultures, literary studies, the social sciences, migrations and the history of energy exchanges across the Atlantic. It aspires therefore to be an informative, systematic, up-to-date historiographical tool available to all researchers who venture into the field of transatlantic relations to better define their hypotheses, research guidelines and conceptual instruments.
