"This collection contains riddles recorded with few exceptions in 1929 and 1930, for a period of time no later than 1928-1929. Accounting for the modern repertoire is the main goal of the collection... The collection reveals what is being thought now, at the turn of the third and fourth decades of the 20th century, on the Russian territory of our Union. In addition to the Great Russian ones, the collection also includes Belarusian riddles. Unfortunately, we were not lucky enough to collect Ukrainian ones during this time..." M.A. Rybnikova
