Primo Analytics from two campuses of the California State University system has revealed that a dramatically low proportion of Primo searches originate from mobile devices. The current study focuses on usability concerns as one area that may be preventing students from searching the Primo mobile interface. The sample for this study includes students from two campuses with a variety of experience with library instruction and searching the library’s discovery system. Participants were given the same set of six common academic tasks to complete. Both mobile and desktop participants found three tasks relatively easy to complete. When there were differences in completion rates between the mobile and desktop users, the desktop users were overall more successful. No task was consistently difficult for desktop users to complete, while mobile users found two of the tasks very challenging to complete. Based on the findings, the authors make recommendations for improving the experience of mobile users.

When the 23-member California State University Libraries merged integrated library systems in 2017, a unique opportunity arose to conduct multi-tenant usability testing on user experience in the Primo discovery service, collectively branded OneSearch. In 2018, librarians at five campuses conducted a round of task-based individual user testing on their separate instances, seeking to review individual campuses’ decisions about customizations designed to provide optimal performance of the system and provide insight into group decisions about our shared customization choices. Along with the findings of the test results and recommendations for enhancements to existing modifications, we discuss the challenges and opportunities that are present in conducting multi-campus usability testing and share recommendations for future consortium-based testing efforts.

The article presents usability tests of Primo VE carried out as part of the implementation of the Alma library services platform at the Nicolaus Copernicus University Library. Remote usability tests were carried out during the COVID-19 pandemic. The aim of the tests was to assess the ease of use of selected system functionalities and the ease of learning how to use them by users. The method of remote usability testing using the Office365 application package, including MS Teams, was used. The tests allowed for the preparation of a report that took into account the identified problems and became the basis for introducing modifications to the configuration of the system's functionality and some elements of its interface, as well as for the preparation of instructional materials. The results indicate a fairly high level of intuitiveness of the interface and the analyzed functionalities. Test participants had no major problems with using Primo, apart from handling facets and full record services.

How do you serve the sophisticated searcher and the novice and make a search interface that serves everyone? How do you help searchers who don’t know what choices to make? Users want a simple one-box search interface but library discovery often requires choices to be made through filters and limiters that are not intuitive. This poster will explore attempts to mediate user discovery through a custom search box and bento style search results seeking to design an interface that works for everyone. We will present data collected from 90,000+ searches conducted over several months and explore how iterative discovery interface changes impacted user behavior and the selection of search results.
