Report on Usability Process and Assessment of Yufind

This document summarizes the results of usability testing conducted on Yufind, an alternative interface for Yale University Library's catalog. Usability tests were conducted to evaluate whether users would see and successfully use facets to filter search results. While facets were sometimes seen and used, subsets did not always make sense and facets were hard to navigate. Based on the tests, recommendations were made to limit the number of facets displayed and make them more focused on user behavior. A survey found that over 50% of respondents preferred Yufind to the previous system and rated it positively. The usability process highlights assessing current user behavior, testing changes, and reassessing to determine standards and priority functionality.
