Using the data shown in the national library statistics system, we tried to identify the current situation from various angles and derive problems, and based on this, we tried to find a development plan. First, it is necessary to conduct a thorough survey to know the statistics of Special library. Second, some degree of unification of the names used in Special libraries should be achieved. Third, it is necessary to present the subject classification for Special libraries. Fourth, it is necessary to actively promote and incentive Special libraries to participate in statistical surveys. Fifth, it is necessary to solve the problem that Special libraries are classified into other statistics. Sixth, statistics of national and large Special libraries such as the Court Library, Constitutional Court Library, and Korea Institute of Science and Technology Information cannot be found anywhere. Unless these problems are solved, the overall evaluation of Special libraries and policy proposals at the national level will be meaningless.
