Recently, the speed of changes surrounding university libraries requires a hybrid library environment that supports integrated services, combining a virtual space with physical space of traditional libraries. Through changes, university libraries have faced the need to review their missions and visions, laying stress on the core values of university libraries. This study analyzed the central keywords in the contents of mission and vision statements of university libraries in America, England, Canada, and Australia. The research was acquired from mission and vision statements containing core values of developed university libraries. Core values are present in each area such as correction and information resources, services, place, people, environment and infrastructure, community, and parent-university relations. Ultimately, this study tried to provide the directions and the basic materials for the establishment of missions and visions for university libraries in Korea.
