I know that the library owns a short film, but the title isn't showing up in NUcat. How come?
Do a “keyword phrase” search in NUcat for the film that you are looking for.
Shorts films usually don't appear when you do a "title" search in NUcat because the short film is part of a collection.
For example: Even Penguins Go to Heaven appears on the DVD titled, A Collection of 2007 Academy Award Nominated Short Films.
Also, sometimes short films are included as part of a DVD's special features.
For example, the short film Cairo as seen by Chahine is included as a special feature on Cairo Station.
