It's hard enough to get a desk sometimes - especially during exams - without people leaving their coats, bags etc on their desk and then leaving the library to go to class, lunch or whatever.
Library policy is that any place left unattended for longer than thirty minutes may be cleared by Library staff for use by another reader. Library attendants do keep an eye on empty desks but please let us know if you feel a desk has been unattended for longer than 30 minutes.
