by 6 points of space. No side dash is used. Reference numbers are not changed to fit the numbering sequence of text footnotes.
15.9.
Footnotes must always begin on the page where they are referenced. If the entire footnote will not fit on the page where it is cited, it will be continued at the bottom of the next page.[1]
15.10.
Footnotes to charts, graphs, and other illustrations should be placed immediately beneath such illustrative material.
15.11.
A cutoff rule is not required between a chart or graph and its footnotes.
15.12.
For reference marks use: (1) Roman superior figures, (2) italic superior letters, and (3) symbols. Superior figures (preferred), letters, and symbols are separated from the words to which they apply by thin spaces, unless immediately preceded by periods or commas.
15.13.
Where reference figures might lead to ambiguity (for example, in matter containing exponents), asterisks, daggers, etc., or italic superior letters may be used.
15.14.
When symbols or signs are used for footnote reference marks, their sequence should be (*) asterisk, (†) dagger, (‡) double dagger, and (§) section mark. Should more symbols be needed, these may be doubled or tripled, but for simplicity and greater readability, it is preferable to extend the assortment by adding other single-character symbols.
15.15.
Symbols with established meanings, such as the percent sign (%) and the number mark (#), are likely to cause confusion and should
not be used for reference marks.15.16.
To avoid possible confusion with numerals and letters frequently occurring in charts and graphs, it is preferable in such instances to use symbols as reference marks.
- ↑ When a footnote breaks from an odd (right-hand) page to an even (left-hand) page, the word (Continued) is set inside parentheses in italic below the last line of the footnote where the break occurs.
A 50-point rule is used above each part of the footnote.
When a footnote break occurs on facing pages, i.e., from an even page to an odd page, the (Continued) line is not set, but the 50-point rule is duplicated.
