I was going to ask this from a Librarian next time I was in the Library, but thought I'll ask here as well (in case someone already knows)
While looking for the availability of a book, I noticed that one of its three copies was loaned out till 02/15/2013 (Web Link)
Given that the Library website says that the loan periods are
"All materials are checked out for 4 weeks (28 days), except for DVDs, which are checked out for 2 weeks (14 days), and the last 6 months of magazines, which are checked for one week (7 days)."
Any thoughts how this is possible?
