In this study, we aim to comprehensively examine how court libraries can enhance their function and role as a hub for judicial information sharing. To achieve this, the current status was holistically understood based on literature review, case studies, interviews with stakeholders, and surveys targeted at users. The study sought to explore and present ways in which court libraries can play a central role in the dissemination and sharing of legal knowledge. As a result of the research, we propose four roles of the judicial information sharing complex center as a court library, five functions of the judicial information sharing complex center, and nine strategies to enhance accessibility for the spread of legal culture. If court libraries function as next-generation shared complex centers with the goal of popularizing legal knowledge culture, it would be possible to expand access to legal knowledge for citizens interested in law and culture, professionals in legal and educational institutions, and residents living near the center.
