The Indiana University Digital Library Program has put online Letopis’ Zhurnal’nykh Statei, “a digitized serial publication that indexes Soviet-era periodicals from 1956 to 1975”:
The paper version, in publication since 1926, covers more than 1,700 journals, series, and continuing publications of academies, universities, and research institutes in the fields of humanities, natural sciences, and the social sciences, and it also covers the popular periodical literature.
Letopis’ Zhurnal’nykh Statei provides access to the periodical literature of an essential time in modern Russian history, beginning with the period of the Khrushchev “Thaw” following the 20th CPSU Congress and continuing through the first half of the so-called Brezhnev “Period of Stagnation”. Virtually any student or scholar studying Russian political science, literature, or history between 1956-1975 will find Letopis’ Zhurnal’nykh Statei to be an invaluable resource.
Thanks for the link, peacay! And I will take this occasion to mention again the indispensable Национальный корпус русского языка, where you can search the entire range of Russian literature from the eighteenth century on to see how a given word has been used.
