On the Loans tab you can track all the media you have borrowed. The due date for return is shown for each borrowed item. Your borrowing period may be shortened if someone else has placed a reservation for the item in question. You receive email notification accordingly in such case. 
Clicking on the arrow right shows you comprehensive information on your borrowed item/s.
