Their usage behavior was investigated, and the satisfaction rate for e-book usage and its service quality were analyzed to comprehend the status of e-book usage. The analysis showed that overall satisfaction for e-book service of university libraries was 2.93 on average. Moreover, the more frequently a student used the service, the more satisfied the student was; junior/senior-level and graduate school student groups showed higher satisfaction for e-book service than freshman and sophomore students. The most influential factor for satisfaction based on the e-book service quality was the content of the service, followed by the library support service system. Based on the findings, reinforcement of library public relations and user education, and the maintenance of the variety and up-to-date status of the contents were proposed to stimulate future university library e-book services.
