Few German poets receive as much attention even in the present day as Friedrich Hölderlin. This handbook, which has been the standard work on Hölderlin research for many years, provides detailed information on the current state of research and knowledge in its new edition. It analyzes the entire body of the poet's work and also addresses his biography in the context of the era, the prerequisites for his work, his poetics, and finally the reception of Hölderlin. This makes various approaches and the diversity of Hölderlin's themes transparent. In the second edition, numerous articles have been rewritten and supplemented.
