Punctuation
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 16.30: “A note number should be placed at the end of a sentence or at the end of a clause. The number follows any punctuation mark except for the dash, which it precedes. It follows a closing parenthesis. . . . For a parenthetical phrase within a sentence, it may occasionally be appropriate to place the note number before the closing parenthesis.” See 16.30 for examples.
