Beyond methodological or ideological principles, Comparative Literature depends upon, and flourishes in, cooperation between different systems, fields and disciplines. We introduce two projects developed by Munich’s Comparative Literature Department as examples of the specific challenges and opportunities afforded by this cooperation: in editing Roman Jakobson’s analyses of poetry, experts in 16 different languages and literatures worked together to present translations, interpretations and commentary on this corpus. In ongoing bilateral teaching and research projects with the German Department at Seoul National University, inter-lingual, inter-cultural and inter-disciplinary communication enables and informs studies focusing on Goethe’s concept of active and passive roles in Weltliteratur, as well as censorship and textual control in divided nations.
