This volume celebrates the 40th anniversary of the journal "American Studies in Scandinavia", which began publication in 1967. This book is an invitation to develop a dialogue across the Atlantic. For too long European scholars have watched Americanists in the United States as though looking through a one-way window, invisible to those arguing on the other side of the glass. For too long US Americanists have scarcely realised that what appeared a mirror could be a window.
