To cite information from a footnote in an MLA in-text citation, include the author’s name and page number as usual, followed by “n” and the footnote number (Bing 205n4).
To cite multiple footnotes, use “nn” and an en dash with the number range (Bing 205nn4–8).
For footnotes without numbers, include a space after the page number followed by “un” (Bing 103 un).
