The volume is a collection of essays by acclaimed and widely published international scholars of space working within different disciplines, such as social sciences, history, applied sciences and media theory, literary and cultural studies (American, Canadian, French, German, Mexican-American, and Polish). Their contributions substantiate the argument that the debate on space has produced a polyphony of argumentation which resulted in the multiplication and diversification of perspectives and interpretations of the studied concept. The volume captures the present state of the most recent debate on space, exploring the importance of its multifaceted nature evinced by the abundance of research on such related terms as border, boundary, and/or region.
