“Tekstologicheskiy Vremennik (Textological Temporary)” continues the series published by A.M. Gorky Institute of World Literature RAS (IWL RAS). The third issue is devoted to a wide range of source study and textual problems associated with the study of ego-literature. Epistolary and diary material predominates in Vremennik, most of which is introduced into scientific circulation for the first time. The publication allows you to form a view of the life and work of Russian writers, the literary process and the history of science in the twentieth century. The attention of the participants of the digest is concentrated mainly on the “ego-documents” of the authors of the Soviet era, letters and diaries of the Silver Age figures and emigrant authors are also considered. The little-studied aspects of textual criticism are updated in connection with this unique material. The publication is addressed to philologists, historians and sociologists, as well as teachers and students interested in the history of Russian literature of the twentieth century.
