The topic in the title consists of two parts. On the one hand there is literarization of oral folklore, in which the aesthetic standard was set for a long time by Fran Milčinski's Pravljice (Fairy Tales) of 1911. On the other hand there are book-lenght fairy tales which touch upon oral folklore only in certain elements, but are, particulary with respect to their subject matter, autonomous works by individual authors. Their pinnacle is Miško Kranjec' Povest o dobrih ljudeh (A Tale about Good People) of 1940. The present study is centered around the latter, while the former is presented more less in passing.
