A special relationship exists between literature studies and libraries; after all, the study of literature mainly takes place in libraries. At the same time, reflections on libraries have repeatedly been characterised by literary concepts. What is the status of this relationship today, however? This anthology seeks answers in areas such as literary and library theory, mediology, literary library research, the mediation and provision of literature through libraries or research on library subjects and metaphors. Knowledge systems, research infrastructures and philological textbooks are also discussed, thereby bringing into focus the day-to-day practice of literary work as a form of self-observation of the modern humanities.
