Nevertheless, the publication of dastans did not wholly cease during that period, as editions of "Alpamysh" were published in 1957, 1958 and 1961, as they had been in 1939, 1941, and 1949; the entry on dastans in the second edition of the "Great Soviet Encyclopedia" (volume 13, 1952) does not contain any "condemnation" either. Despite the liberalization of the political climate after the denunciation of Stalinism by Nikita Khrushchev in February 1956, the same "Barthold" edition of the "Book of Dede Korkut" was re-published only in 1962 and in 1977. Problems persisted all the way to perestroika, when the last full edition in Azerbaijani language was sent for publication on July 11, 1985, but received permission for printing only on February 2, 1988.
