NOTE: The format of citations for multivolume works depends on a number of variables, including whether all volumes were published in the same year, whether individual volumes have a single author or multiple authors, whether the set has an editor, and whether each volume has a unique title. If you are unsure of how to cite a multivolume source you've used, it is best to consult the MLA Handbook (5.5.14).
