Book excerpt: Borders and border regions are shaped by many phenomena connected with both co-operation and conflict. The neighbourhood, cross-border contacts, illegal migration, border crossings, prejudices and stereotypes, border guards, and perceptions of borders are some of the key words that characterize the articles in this volume. The book deals with European border regions that have experienced numerous changes over the 20th century. Because of this changeable, frequently painful past, different human stories – mostly tragic or romanticized – individual and collective memories, mythologies with heroes, and divergent perceptions of history developed. Most authors in this volume deal with conflicts and co-operation that can either be remembered or forgotten.
