Locating Spanish (and other language) titles in the catalog

We've had a couple of students in asking for Spanish language movies - evidently a class assignment.   The easiest way I've found to limit to a language is to click on DVD (or books or articles)  in the red box - type in spanish (or another language)  as a keyword, but then you also need to use the left side bar limits to restrict results to titles in the language - otherwise you can get Spanish titles dubbed into English or translations of Spanish novels or even the word Spanish as part of the title.
