How to use MLA for a paper in Spanish? I'm currently working on a Spanish paper in MLA for an undergraduate course and have stumbled on some confusion for my Works Cited for which I can find no definitive answer. MLA says that I should use the header "Works Cited" before my citations, but does this still apply for other languages? Should I put "La bibliografía" or "Las referencias bibliográficas" instead? Thank you!
I have always used/seen for MLA in Spanish, and instruct my students to use Obras citadas.  In truth, Bibliografía is vastly more common in native-Spanish, non-MLA works, but the same could be said of English Bibliography.  

Since MLA keeps the references to strictly the works that were, well, cited (as opposed to read during research or useful for further reading), thus making a difference between a bibliography and a list of works cited, it has always seemed logical to me to make the same distinction in Spanish.  

And just to give you a specific reference, grabbing a random journal I have here —Hispania, which generally uses MLA— references for articles are found in a section entitled Works Cited (English) or Obras citadas (Spanish/Portuguese).
