As university libraries provides a lot of electronic resources collections and services, faculty members and graduate students regard them important and highly useful. Electronic resources bring a lot of complex problems, therefore, it is necessary to from views of users to conduct service quality measurement for electronic resource services for university libraries. It can help library managers to provide electronic resources services in line with user expectations in the future. The main aims of the study are to construct indicators of electronic resources service quality; to explore implications and availability of electronic resources service quality measurement; and to implement electronic resources service quality measurement to improve service quality, then providing the better electronic resources services. This article used focus groups to develop the service quality model of electronic resources service composed of three dimensions and 28 indicators. Focus group interviews results were used as a basis for the development of questionnaires. In order to ensure the feasibility of service quality model, questionnaires have been collected from faculty members and graduate students of the C University. The study shown that the service quality model of electronic resources service was feasible. The overall average expectation score of electronic resources services was 4.07, an average perceived service score was 3.61, and there are a gap between the expectation and perceived service from respondents which meant the service quality of electronic resources were not excellent. The study proposed ten most expected of electronic resources services from faculty members and graduate students and eight dissatisfactory electronic resources service and some recommendations were made for improvement.
