Expanding on previous research, the authors applied quantitative and qualitative methods to investigate Web usability policies, standards, and guidelines (PSGs); resources; and usability testing, including mobile testing and usability laboratories, at the academic members of the Association of Research Libraries (ARL). Survey results indicated that less than 50 percent of the libraries have Web usability PSGs. The perceived importance of usability testing has a significantly positive correlation with the testing performed, ARL ranking, mobile website testing, and availability of usability laboratories. Limited resources hindered initiatives aimed at improving usability. The authors suggest that library administrators integrate Web usability into their strategic priorities, thereby enhancing users' experience in academic endeavors.
