Advanced information technology has changed our society in various aspects. University libraries are also changing with the adoption of advanced information technology. Specifically, digital technology including the Internet has changed traditional university libraries in their operations as well as infrastructures. Traditional university libraries have stored and distributed scholarly information in printed media. However, most of current university libraries are hybrid libraries, which are dependent on digital media as well as printed media, and are based on both network facilities and physical facilities. The evaluation metrics developed for traditional university libraries are no longer adequate to evaluate current university libraries. This paper presents an evaluation of hybrid libraries. Based on the opinions of library experts and the previous works on the evaluation of both traditional and digital libraries, an initial evaluation model was developed, which consists of 8 categories, 33 items, and 84 indicators. The Delphi method was then applied to develop a valid evaluation model for university libraries. A survey was conducted 3 times for 50 balanced subjects among library-related professors, researchers, and senior university librarians. Based on the surveys’ results, the categories, items, and indicators were modified to derive the new evaluation model, which consists of 7 evaluation categories, 35 items, and 92 indicators. The content validity of this model was confirmed through the survey results of 184 university librarians.
