My card is expired or will expire shortly. I don't understand that. I am a current student.
All 'cards' expire at the end of each term. It's automatic. Since the library's standard check-out is 3 weeks, in the last 3 weeks of the term, the library system gives a message that the user 'card' will expire shortly. It lets the library staff know that the circulation period is less than the standard period.
Within the first week of the new term, after the final add/drop day, current students are rolled into the library system from Banner. If you need to check out a book in the first few days of classes, just bring your current schedule from Banner to show the Library staff at the desk, or library staff can look up your status with your 900#.
