Sterling Memorial Library

Yale University's Library Security Department oversees the security in Sterling Memorial Library and Bass Library.  Both libraries contain material of great culture, research and monetary value - material which must be guarded with great care if use is to be made of the material by those who need it.

The staff of the Library Security Department enforces the library's policies, rules and procedures with respect to the operations, security and safety of the library, its collections and occupants.

Library Security personnel are not officially connected with the Yale or the New Haven Police Departments, but the department works in close cooperation with these agencies when necessary.  The staff of the Library Security Department may be seen as supplements to the Yale Police, another facet of the campus-wide effort to achieve security for the Yale community.
