User-Centered Evaluation of a Discovery Layer System with Google Scholar
This study compared the search results and usability of a discovery layer system (Ex Libris Primo) to Google Scholar. 12 graduate students performed search tasks on both systems and rated the relevance of the top 10 results. While the relevance of results was generally comparable, users rated Google Scholar significantly higher than Primo in usability and preference. Analysis found usability issues with Primo's workflow between search, results, and full text as well as consistency. The study concluded that discovery layers need improved user interfaces to address these usability problems.
