Contrary to popular belief, MLA format was not designed by English teachers as a torture technique. It is used to keep you in the legal clear zone while writing. MLA format establishes guidelines that allow you to include academic research without being suspected or (worse) convicted of plagiarism. It also allows those reading, be it professors or scholars in your academic field, the chance to see where you are getting your evidence to support your claims.
The best one stop shop for MLA format is the Purdue Owl, which can be found at this web address: https://owl.english.purdue.edu/owl/resource/747/01/
This website gives not only the rules, but examples of citing sources in different medias (print, web, video). When in doubt I always look to Purdue. Save yourself time and trouble and bookmark it right now.
With their specific examples you will be on your way to a beautifully cited research paper.
