As librarians increasingly support digital publication platforms, they must also understand the user experience of these tools. This case study assesses use of Scalar, a digital humanities publishing platform for media-rich projects, at the University of Illinois at Urbana-Champaign. Based on a survey, interviews, and content analysis, the study highlights the platform's usability, its functionality, and its successes and failures in meeting user expectations. The media upload process, image annotation, and aesthetics factored into user issues. Writing pedagogy also emerged as an important consideration. Results suggest lessons for digital literacy instruction, as well as how and when Scalar might serve patrons' publishing needs.
