Journal Article Quotes Or Underline

Underline or quote title of an article or journal?
I’m writing an MLA format essay and I’m not sure if I should underline the title of an article in a journal or put quotation marks around it. Also, do I underline the title of the journal or quote that?
Thanks,
Zak
Modern Language Association (MLA) citation style for a Works Cited list calls for the title of the article to be placed in quotation marks; and the journal’s title to be underlined.
For examples of the above, including punctuation, and the rules for the other information required in the Works Cited entry, please see:
