The CSI Library aims to provide a quiet and comfortable study environment. Noise from the use of cell phones is disruptive to this environment. Therefore, the use of these devices in the Library is strictly prohibited. The Library requests that all cell phone users set their phones to vibrate while they are in the building. Persons wishing to receive or make cell phone calls may do so in the entrance lobby on the first floor. Library staff reserves the right to ask anyone to leave the Library if she/he is using a cell phone or disturbing others in any area of the Library.
