The collection assembles, defines, and examines texts which can be labeled as "liminal texts". These texts deny a classification into traditional systems, genres, and forms valid around 1880 and continuing into the first decades of the 20th century where broadly effective innovations in the sciences, the arts, in politics and society took place in France, Austria and Germany. The anthology not only provides a new corpus and therewith innovative insights into the long turn of the century but also an experimental field for current theoretical and methodological questions.
