In celebration of the 30th anniversary of the founding of the Korean Oral Literature Society, this study summarizes the research results in the field of shamanic songs over the past period. Shamanic songs are a part of a whole called shamanism. Therefore, we must understand the shamanic research flow within the overall flow of shamanic research, and within that flow, we can discuss the trends, characteristics, and achievements of research in the oral literature society. From this perspective, this study first organized the flow of shamanic research and how the scope and existence of shamanism, the subject of research, were recognized.
 Korean shamanic research began in the 1960s. Representative researchers were Seo Dae-seok, Kim Tae-gon, and Choi Gil-seong. Among them, Seo Dae-seok and Kim Tae-gon were scholars of Korean literature. Their research trends were clearly distinguished. While Seo Dae-seok made efforts to establish shamanism as 'literature', Kim Tae-gon conducted 'folk' research to understand shamanism in general. As the Korean Oral Literature Society was founded around Seo Dae-seok, the study of 'shamanic songs' as literature was the most central research trend. On the other hand, Kim Tae-gon's research trend is centered around the Folklore Societies and 'Association for Korean ShamanisticStudies'.
 『Oral Literature Studies』, the academic journal of the Korean Society of Oral Literature, has published 726 papers so far, of which about 120 are related to the study of shaman songs. These studies were divided into 1) Research on shamanistic Epics, 2) Comparative research with overseas narratives as oral narratives, 3) Research on shamanic songs other than shamanistic Epics, 4) Shamanic research using shamanic songs, and 5) Other research. They were organized. Consequently, the Oral Literature Society's research results in the field of martial arts over the past 30 years have emphasized the study of martial arts as literature and strengthened its differentiation from folk research. A clear line has been drawn in terms of academic identity. However, as a result, the focus on shamanistic Epics research and text analysis research without a basis for field research are pointed out as limitations. In addition to this, the researcher proposed to expand the research from the perspective of ritual language and expression (performance) beyond shamanic song.
