Most Penn libraries are open to the public (with a photo ID) on weekdays. On evenings and weekends, students with a valid photo ID from Drexel, Bryn Mawr, Haverford, Swarthmore, St. Joseph's or Villanova, or a SHARES partner (including Temple, Princeton, and Penn State), may access the Van Pelt-Dietrich Library Center. Please see the Penn Libraries access information page for more details.
