Exiting the Libraries
All persons leaving the library must pass through the electronic loss prevention system installed at the exits of the Lauinger and Blommer Science libraries. Occasionally non-library materials, such as rented videos or books from a bookstore, may activate the detection system. If the alarm sounds, you must present all materials for inspection to the security guard or a library staff member. Intentional removal of library-owned materials that are not properly checked out will result in disciplinary action.
