Four liaison librarians from very different disciplines (including Biology, Business, Media Studies, Social Work, and Writing) conducted a series of usability tests in Spring 2018. They asked participants to complete a series of tasks using James Madison University subject guides, and all screen activity and voices were captured using Morae Recorder. The results were fascinating, enlightening, and immediately useful. The research team is currently sharing practical implications from our findings with colleagues via a “Tip of the Week” email.
