Follow these instructions to cite a newspaper article in MLA format (from the Purdue OWL):
Cite a newspaper article as you would a magazine article, but note the different pagination in a newspaper. If there is more than one edition available for that date (as in an early and late edition of a newspaper), identify the edition following the date (e.g., 17 May 1987, late ed.).
If the newspaper is a less well-known or local publication, include the city name and state in brackets after the title of the newspaper.
