    At the Valley Library, we engage in regular assessment of hours and spaces.  To make decisions about open hours, we consider:

    Campus and state guidelines for health and safety;

    Staffing levels needed to deliver services and ensure that spaces are kept usable and comfortable;

    How many people are using library spaces and services, and when;

    What other study spaces and services are available on campus, and when they are open.
