By means of interviews, translations, reproductions, and theoretical and historical statements, OEI # 90-91 offers a picture of a very lively scene of concrete and visual poetry in Yugoslavia, which unfortunately is not as recognized interna-tionally as it would deserve. Hoping that OEI # 90-91 could contribute to this task in a substantial way, we present episodes from the early years of OHO formation and its complex theories of words and things; an interview with Rastko Močnik on programmed art and political formalism; militant polemics of Goran Babić; Signalist contradictions; subjective structural devices of Judita Šalgo; zaum experiments of Vojislav Despotov; detective meta-texts of Slavoj Žižek; poetic self-management studies of Vujica Rešin Tucić; a feminist historicisation of Ažin school for experimental poetry; democratisation of visual poetry by Westeast; selections from special issues of the journals Pitanja, Problemi, Ulaznica, Dometi, Delo, Koraci, Vidik, Pegaz, and many other materials translated here for the first time and presented in one publication.
