Zabolotsky’s poetry in the circle of the Philological School in Leningrad. Alexander Kondratov’s poetry cycle OBERIU (Roots) is published for the first time. The cycle is analyzed in the context of Kondratov’s scholarly writings on information theory and literary studies, with references to his correspondence with R. Jacobson and the publishing history of the heritage of D. Kharms, A. Vvedensky. The study is based on archival sources.
