The volume Regeln der Bedeutung ('Rules of meaning') marks the launch of REVISIONEN, a projected series of some eight volumes on basic concepts of literary theory. The series aims to reflect on central concepts of literary studies which have become questionable or problematic in the course of recent debates and to open up new perspectives on them in order to make them available for research in a new manner. Such concepts include, for example, 'meaning', 'literature', 'interpretation'. The series takes an interdisciplinary approach, drawing not only on literary theory but also on art history, music, philosophy, linguistics, and psychology.
