Phones

  • Cell Phones: Please be respectful of others and keep calls brief.  Extended calls should be taken in the Café or the area inside the front doors.  If you are disturbing others, we may ask to you end your call or move to a different area.
  • Red phones are located throughout the libraries for on-campus calls (using four-digit campus extensions).
  • A phone for local calls (314 area code) is located on the second floor near the elevators.
