Different from the existing tendency to mainly concentrate on the study of research activities of the library and information science, this paper places the focus on grasping research patterns presented in the journal papers which reflect library Practices. Actually, this paper analyzes research areas, the degree of relative dependence by subjects, and leading journals found in the papers which have been reported in the three main library journals such as "Tosogwan", "National Assembly Library Review", and "KLA Bulletin : Tosogwanmunwha" from 1996 to 2000. As a result, the study says that major research areas in library practices show the high degree of dependence on the library and information science, while the degree of dependence on the information science is low.he information science is low.
