The Department of Library and Information Science was established in March 1964 as a library department with 20 admissions quota. After that, in 1971, a master's course in graduate school was newly established, and in March 1974, a doctoral course in this study was established for the first time in Korea. In March 1991, the department was renamed Library and Information Science in response to internal and external changes in the information society. As of 2026, the number of graduates has reached about 2,000 over the past 60 years. These alumni play a leading role in various fields such as Korean librariess, media and publishing, public institutions, and IT fields. The Department of Library and Information Science aims to maintain social effectiveness by continuously operating subjects in the traditional subject areas of library and bibliography, while providing more professional undergraduate education in the field of information by reflecting the current trend of the "digital era" and "big data era." As part of this, the Department of Library and Information Science obtained membership for the first time in Korea as an international iSchools organization. It is currently operating a new data science curriculum that trains data scientists in the big data era.

The research area of literature information technology is very wide ranging from information system and IT fields, information management and search, information classification and organization, and ancient literature management to information center management. The research field is largely divided into three areas: social science aspects related to overcoming information problems, humanities aspects for analyzing the organization, content, and types of information of knowledge, and engineering aspects of digital libraries and databases. Therefore, library and nformation field can be said to be a science with convergence-complex characteristics between interdisciplinary systems. The educational goal of this course is to understand the general theories and methodologies of these various areas and to have basic qualities as information and data experts to respond to user needs and organizational and social information needs through the application of IT. Due to the nature of library and information science, practical understanding of practice is required, and industry-academic cooperation classes are actively conducted as well as lectures by external experts at the master's and doctorate levels.
