Do you have a list of available movies? Or do you have to search individually and know what you are looking for?
There is a spiral bound list of movies at the Fondren circulation desk which you can browse. Otherwise you have to individually search for the movie title using the "Discover SMU Libraries" search box. When you get there, you must put at least one keyword, it could be a country or a genre like horror or women, etc. You will get a results screen, and go immediately to the left sidebar to "content type" and choose "video recording". If you click on a title, you will get another screen telling you if it is in and the call number -- if it says "not checked out" bring the call number to the circulation desk to get it.
