Two branches, each with distinct user groups, the Ferriss Hodgett Library in Corner Brook, and the Health Sciences Library in St. John’s, conducted unique usability studies to gain evidence into how WorldCat Local performed common research tasks. The Health Sciences Library was inspired by the information seeking habits of Memorial University’s Faculty of Medicine, School of Nursing, and School of Pharmacy. This demographic’s heavy reliance on journal literature, and known item searching made these users an interesting test group. The Ferriss Hodgett Library, serving an undergraduate Liberal Arts and Sciences population, was interested in the information seeking behavior of new students with little to no experience using library resources. At the local level, evidence obtained as a result of this usability testing will provide guidance into future use of WCL at Memorial University Libraries. On a broader scale, the usability findings are relevant to any library considering the shift to a new discovery tool.enAttribution-NonCommercial-NoDerivatives 4.0 InternationalUsability testingAcademic libraryDiscovery toolInformation seekingUsabilityArticle
