A fairly significant production and publication of literature in Chuvash still continues. According to UNESCO's "Index Translationum", at least 202 books translated from Chuvash were published in other languages (mostly Russian) since ca. 1979. However, as with most other languages of the former USSR, most of the translation activity took place before the dissolution of the USSR: out of the 202 translations, 170 books were published in the USSR and just 17, in the post-1991 Russia (mostly, in the 1990s). A similar situation takes place with the translation of books from other languages (mostly Russian) into Chuvash (the total of 175 titles published since ca. 1979, but just 18 of them in post-1991 Russia).
