This study investigated and analyzed the degree to which the '3rd Library Comprehensive Development Plan' established in Korea is related to the UN SDGs agenda, including whether the library does business or services related to the UN agenda. As a result, first, IFLA welcomed the UN 2030 Agenda by supporting the UN 2030 Agenda, that is, by presenting the library's specific implementation strategy to achieve the 17 goals of the SDGs. Second, all 14 Core tasks of the '3rd Comprehensive Library Development Plan' were found to be closely related to UN SDGs. Among them, it was analyzed that the convenience of access to user information, including the linkage of library information services, and the strengthening of library services tailored to the life cycle were most strongly related to this agenda. The results of this study are expected to help the community, government, local governments, and the public to appreciate the social contribution and value of the library.
