Jennifer C. Hill and Christine Patterson recently published an article, Assessment from a distance: A case study implementing focus groups at an online library, in College & Undergraduate Libraries.
Their article delves into the complete process of piloting virtual focus groups—from planning and implementation through the analysis of results for a completely online student population. The virtual focus group method proved effective in getting qualitative feedback to spur library improvements, and it is transferable to many different library settings.
