A Usability Evaluation Model for Academic Library Websites: Efficiency, Effectiveness and Learnability

Purpose – This paper aimed to develop a usability evaluation model and associated survey tool in the context of academic libraries. This study not only proposed a usability evaluation model but also a practical survey tool tailored to academic library websites.Design/methodology – A usability evaluation model has been developed for academic library websites based on literature review and expert consultation. Then, the authors verified the reliability and validity of the usability evaluation model empirically using the survey data from actual users.Statistical analysis, such as descriptive statistics, internal consistency test, and a factor analysis, were applied to ensure both the reliability and validity of the usability evaluation tool.Findings – From the document analysis and expert consultation, this study identified eighteen measurement items to survey the three constructs of the usability, effectiveness, efficiency, and learnability, in academic library websites. The evaluation tool was then validated with regard to data distribution, reliability, and validity. The empirical examination based on 147 actual user responses proved the survey evaluation tool suggested herein is acceptable in assessing academic library website usability. Originality/Value – This research is one of the few studies to engender a practical survey tool in evaluating library website usability. The usability model and corresponding survey tool would be useful for librarians and library administrators in academic libraries who plan to conduct a usability evaluation involving large sample.
