Numbering notes
Notes-bibliography style: the basic form
Part II. Source Citation

Number notes consecutively, beginning with 1. If your paper has separate chapters, restart each chapter with note 1. Do not skip a number or use numbers such as 5a.

If you use endnotes for source citations but footnotes for substantive comments (see 16.3.1), do not number the footnotes. Instead, label the first footnote on a page with an asterisk (*). If you have more than one footnote on a page, use superscript symbols in the sequence * † ‡ §.

For notes to tables, see 26.2.7.
