This edition publishes for the first time 348 letters from P.V. Annenkov based on archival materials from the Manuscript Department of the Institute of Russian Literature. They had never been published in full before. Meanwhile, the letters are of scientific interest not only for characterizing Annenkov as a critic and eyewitness of his time, a man of enormous knowledge, but also reveal his amazing friendship with I.S. Turgenev. The first book includes part of the epistolary heritage of P.V. Annenkova. The letters are arranged chronologically, starting from 1852 to 1874. The appendices include an explanation “From the Compilers”, materials for the biography “Conscientious Eyewitness” N.G. Zhekulina, “The Story of a Friendship. Correspondence of P.V. Annenkova with I.S. Turgenev" N.N. Mostovskoy and comments.
