While Lermontov was alive, a separate publication of A Hero of Our Time was released (St. Petersburg, 1840, ed. by A. A. Krayevsky, pub. by I. N. Kushinnikov and A. D. Kireev). Lermontov revised the text of the chapters previously published in journals and made various corrections. The novel was approved by the censor on 19 February and was published on 27 April. Lermontov did not read the proofs, since from 10 March to mid-April he was under arrest for a duel with E. Barant. The book has uncorrected scribal errors and misprints. The novel was released in two parts. The edition was sold out, and already in 1841, Lermontov sold Kireyev the rights to a second edition, with a run of 1,200 copies. In this edition (St. Petersburg, 1841) Lermontov made a few corrections; otherwise it repeats the first, including the same pages and lines. The preface first appeared in the 1841 edition; it apparently arrived during printing and therefore was printed with a separate pagination and is not included in the table of contents. Both editions had minor cuts made by the censor.
