Purpose – The purpose of this paper is to determine the usability of the mobile library App of
Chongqing University and to provide recommendations for improving the experience of App users.
Design/methodology/approach – Usability testing, which comprised pre-test questionnaires,
accomplishing tasks, and post-test surveys, was conducted in this study. The effectiveness and
efficiency of the App, as well as user satisfaction with it, were measured.
Findings – The mobile App was proven effective but the efficiency of the App required improvement.
With regard to user satisfaction, the factors “clarity” and “usefulness” received the lowest and highest
scores, respectively. The deions of mobile services were unclear and confused users; nonetheless,
the services provided by this App were appealing and useful to the users. Based on the measured user
experience, this study proposed several recommendations for enhancing the usability of the App.
Originality/value – An increasing number of domestic and foreign libraries have begun to use
mobile Apps to provide new services to patrons. In the future, smartphones are likely to become crucial
to the delivery of information services. Given the extensive use of the Super Star Mobile Library
system adopted by Chongqing University Library in China, the usability of such a system must be
investigated. Improving the usability of the mobile library App can help enhance user experience.
