This book examines the ways in which scholarly expertise was mobilized during the First World War, and the consequences of this for the inter-connected academic world that had developed in the late nineteenth century. Adopting a strong international approach, the contributors to this volume examine the impact of the War on individuals, institutions, and disciplines, cumulatively demonstrating the strong afterlife of conflict for scholarly practices and academic communities across Europe and North America, in the decades following the cessation of the Great War.
