When you use study carrels in the Library, you might have experienced this situation: you leave the seat but use your belongings to keep it occupied; when you return, someone else take your seat, and you see a notice to claim your stuff at the G/F Service Counter. How did that happen? Yes, library staff takes regular actions to reduce "seat hogging". We conduct "in-depth patrol" to clear study carrels and make them available for library users. How does "in-depth patrol" work? When we see a carrel occupied by unattended belongings, we leave a paper slip noting the time. After 30 minutes, if the belongings are still there, we would put them on the side so that the seat is available for another user. Valuables will be sent to G/F Service Counter for keeping your belongings secured. In this Fall term, we did such patrol between 26 September and 1 November; and we cleared a total of 316 carrels, averaging 12.6 carrels per day. That is a 43% increase from last year!
