The purpose of this study is to inform the variables affecting the use of digital library, user satisfaction and net benefits perceived by Indonesian open university (IOU) students. The merge of the technology acceptance model and the information system success model was proposed.
Through a large-scale survey, the instrumentation was validated and examined for the reliability through some steps: face and content validity, pilot study and measurement model. In the data collection phase, 2,695 IOU students participated in filling out the survey instrument. The data were computed in the SmartPLS application and analyzed through a structural model evaluation, the partial least square structural equation model.
The analysis informed that most hypotheses were confirmed, informing the roles of all exogenous variables to the endogenous. The most significant determinant of use of digital library was perceived usefulness. User satisfaction was mostly influenced by perceived ease of use. Meanwhile, the strongest determinant of net benefits was user satisfaction.
By integrating these two models, this study is expected to provide deeper insight into how and why open university students use digital libraries. The current study provides recommendations for further improvements. It seeks to fill the research gap regarding the use of information technology in the context of open and distance education.
