Where you'd normally put the author's last name, instead use the first one, two, or three words from the title. Don't count initial articles like "A", "An" or "The". You should provide enough words to make it clear which work you're referring to from your Works Cited list.
If the title in the Works Cited list is in italics, italicize the words from the title in the in-text citation.
If the title in the Works Cited list is in quotation marks, put quotation marks around the words from the title in the in-text citation.
