We have implemented this system for a number of reasons, all of which are designed to ensure the well-being of our patrons and library staff. First, it enables us to track how many people are using the facility and thus stay within the occupancy limits we have established for safety. Second, it alerts us of which seats, desks, rooms, or pcs need to be cleaned after use. Third, it acts as a means of contact tracing. If you have any questions about this policy, please contact University Librarian Paul O. Jenkins.
