Since 2016, the University of Mississippi Libraries has used ExLibris’ Summon for their discovery service, locally known as One Search. During the implementation, customizations for the search results page were determined by a committee of librarians. As new settings and customizations were implemented over the years, librarians began to question if certain settings were appropriate or if the patrons were actually using them. An IRB approved survey was distributed asking library patrons about their use of One Search while library employees were asked to answer how they perceived patrons used it. Results showed the differences between library employee perception of use and how library patrons used specific facets and settings. This paper seeks to investigate the similarities or differences between library expectations regarding patron use of One Search versus those revealed by library patrons themselves.
