We report on recommendations to remove barriers to worldwide development of digital libraries, drawing upon an Aug. 2000 workshop involving researchers from the US and Korea who met at the San Diego Supercomputer Center. We developed a summary table identifying application domains (e.g., education), institutions engaged in those applications, example activities, technical challenges, and possible benefits. Since education has high priority in Korea, an important opportunity that should be explored is involvement of Koreans in the initiative led by the US NSF to develop the National STEM (Science, Technology, Engineering, and Mathematics) education Digital Library, NSDL.
