E.A. Hoffmann von Fallersleben (1798-1874), Grimm adept, philologist and Vormärz poet, maintained an exensive correspondence with many European partners throughout his life. His letters have been repertoried by Dr. Erika Poettgens as part of her study Hoffmann von Fallersleben und die Lande niederländischer Zunge. Briefwechsel, Beziehungsgeflechte, Bildlichkeit (Münster: Waxmann, 2014). By courtesy of Dr Poettgens, and with the kind help and agreement of Waxmann publishers, SPIN was given the use of the corpus’s metadata. These were processed to put a visualization of Hoffmann’s network online. It can be accessed in the ERNiE website (http://ernie.uva.nl) under the “Letters” tab, or directly through this URL: https://ernie.uva.nl/viewer.p/21/59/scenario/114/geo. Hoffmann’s 7600 letters now feature in ERNiE alongside other major corpuses (the Grimms, Walter Scott, E.M. Arndt, Rasmus Rask, Prosper Mérimée...) to demonstrate the densely and transnationally entangled nature of Romantic Nationalism.
