The document discusses a project at a university library called "Every Seat Counts" which aimed to address the problem of students reserving library seats by leaving personal items on desks when not in use. Observational studies found that a third of students who entered the library in the mornings left within an hour, while many seats remained occupied by unattended belongings. The library implemented patrols by student monitors to remove unattended items after 45 minutes, placing them in a collection box. Surveys found students supported the new policy as it increased seat availability during peak periods. The project helped enforce an existing rule while maintaining a welcoming environment.
