Use a superscripted Arabic number within the text of your paper to indicate that the reader should refer to a footnote. In general, superscripted numbers should be positioned after marks of punctuation such as commas and periods. Do not place superscripted numbers after dashes.
Begin your footnoted section four lines, or two double-spaced lines, below the main body of the text.
Begin your footnote with a number that correspond to the superscripted number in the text, followed by a period and a space before beginning the note. For example, if a superscripted number 1 indicates that your reader should refer to a footnote, that footnote should begin with "1." followed by a single space.
Position the first line of your footnote so that the number is indented five spaces in from the left margin. Subsequent lines of the same footnote should line up with the left margin in the main body of the text. Note that footnotes should be single-spaced.
