“…For example, MIT Libraries used a post-sorting category test, in which users list items they would expect to find under a given category, and a reverse category, in which users are asked to select a category label in response to a task-based scenario (Hennig, 2001). Later studies have adopted a similar multi-step approach for validating categories developed through card sorting (Duncan & Holliday, 2008;Hepburn & Lewis, 2008;Whang, 2008), while others have incorporated card sorting as one part of a broader user research and redesign process (Hepburn & Lewis, 2008;Robbins, Esposito, Kretz & Aloi, 2007;Turnbow, Kasianovitz, Snyder, Gilbert, & Yamamoto. 2005;Ward, 2006).…”
