• Dixon-Kennedy, Mike - Encyclopedia of Russian and Slavic Myth and Legend
"The Encyclopedia of Russian and Slavic Myth and Legend provides lengthy, illustrated A-Z entries on the myths and legends of Russia and other Slavic countries, such as Poland and Slovakia. Besides a good bibliography (p. 327-330), a glossary, a list of the rulers of Russia and an index, this thoroughly cross-referenced work contains a topic-finder (p. 337-352) which arranges entry-headings by both country (Ukraine) and category (Mythical places and objects)."
