This study examines the current status of 21 virtual university libraries in Korea and explores the possibilities of establishing a national-level central digital library through which these libraries could share resources. Interviews were conducted with 16 virtual university administrators to investigate their opinions and requirements of a central digital library. It was found that many virtual university libraries do not provide sufficient library resources and services due to a lack of qualified librarians and necessary funds. The interviewed administrators were willing to participate in a central digital library initiative to benefit from joint acquisition of databases and resource sharing, but they wanted to ensure local autonomy and control in managing their digital library sites. Therefore, the present study proposes a hosting model in which shared applications and resources reside on a central server and users from different universities access them remotely through the interfaces of individual library sites.
