The 24-hour/5-days-per-week (24/5) model at Belk Library & Information Commons has experienced multiple changes since first implemented in 2006. First the library started small, then expanded, then reduced, and finally expanded again. This article tells the story of a library's 24/5 evolution within the assessment cycle framework, describes how data and perspective played a role in decisions, provides data on overnight head counts, offers a glimpse into the types of activities engaged in by students during overnight hours, describes student led advocacy efforts to reinstate library hours, and provides an overview of operations and security officer protocol.
