The final work in the first chapter briefly explains the concept of bibliotherapy based on the handbook of the same name by Ivana Bašić. In the second chapter it discusses the definitions of the fairy tale according to literary dictionaries, and then describes its structure based on the work Morphology of the Folktale (1982). by Vladimir Propp. It further traces the development of the fairy tale from its earliest appearance to the modern day. After that, it explains the therapeutic role of fairy tales according to Bruno Bettelheim from his work The Meaning and Importance of the Fairy Tale (2000) in which, according to his life experience and work, he described famous folk tales and their therapeutic influence on readers from their early youth to the mature period. The final chapter of the work is divided into three author's approaches to fairy tales with an emphasis on bibliotherapeutic influence. They are Bruno Bettelheim, Gerlinde Ortner and Olga Huhlaev. It shows how psychologist and therapist Bruno Bettelheim interprets the influence of folk tales, and how psychologists Gerlinde Ortner and Olga Huhlaev interpret modern fairy tales with bibliotherapeutic effects. Ultimately, it was concluded that all three approaches are based on addressing the reader's subconscious and identifying with his or her current emotions and bringing a temporary and permanent solution to each problem through the awareness that the same is found in the reader himself or herself.
