Subject Guides at the Carleton University Library were built in 2011 on a home-grown Drupal template, mirroring the tabbed design of LibGuides. By 2015, the number of tabs in use was making the guides unwieldy in mobile and even on larger screens. The Library’s Web Committee wanted to design a guide that would be user-friendly for students, while also meeting the needs of another significant user group: library staff. Through user research with both groups and user testing with students, we came up with a design to meet the needs of both students and library staff. This presentation will give a quick tour of our new design, emphasizing how user research drove our design decisions and helped with staff buy-in.
