Q. When using a superscript footnote number at the end of a sentence, should the period precede or follow the footnote number? What about footnote numbers in midsentence that fall next to some other form of punctuation (comma, semicolon, etc.)?

A. Please see CMOS 14.26: “A note number should generally be placed at the end of a sentence or at the end of a clause. The number normally follows a quotation (whether it is run into the text or set as an extract). Relative to other punctuation, the number follows any punctuation mark except for the dash, which it precedes.” Paragraph 14.26 also includes examples.
