Officials anticipate that the March 16 switchover will not cause many problems - students have been able to access the Olin library without an ID card up until midnight - the new program just moves the time back three hours. The reason for the change? Uniformity - other buildings on the Washington University campus are open only until 9 PM, and administrators wanted to ensure that every building on the campus has the same access control policy.

While the hours of operation for the Olin Library and Whispers Cafe will not change, the new access control program is a good example of how many schools and other large organizations are creating card programs and rules to help ensure uniformity and security.
