This study was conducted to analyze research behaviors of bibliotherapy studies in order to improve the level of bibliotherapy study in the LIS. 130 articles of journals were divided into five major fields, and analyzed using major areas, research subjects, research methods, affiliation of authors, and participants. The results showed that bibliotherapy studies in LIS have been conducted rather broadly by the practitioners ever since the 2010s. However, diversification of research topics, research methods, and theoretical foundations are found to be problems that need to be solved. Based on the statistics, suggestions are made: to expand the target of bibliotherapy to various ages, classes, experience groups, and situation groups; to combine reading books with further activities such as discussion, role-play, and play therapy; to take advantage of a variety of diagnostic test tools and to utilize clinical treatments; to conduct qualitative and quantitative research simultaneously in order to achieve the benefits.
