Are you referring to DVD's being loaned by the Instructional Media Services (IMS)? Currently we have 2 individual viewing rooms at the 7th floor (more to come, soon!). To be able to use one, first borrow a DVD from IMS, 6th floor. First come, first served.
Extra tip: The American Corner at the 13th floor has a large screen TV in its activity area that you can request to use if no one's using it!
