Chapter 13

13.67.

Superior figures are used for footnote references, beginning with 1 in each table.

13.68.

If figures might lead to ambiguity (for example, in connection with a chemical formula), asterisks, daggers, or italic superior letters, etc., may be used.

13.69.

When items carry several reference marks, the superior-figure reference precedes an asterisk, dagger, or similar character used for reference. These, in the same sequence, precede mathematical signs. A thin space is used to bear off an asterisk, dagger, or similar character.

13.70.

Footnote references are repeated in boxheads or in continued lines over tables.

13.71.

References to footnotes are numbered consecutively across the page from left to right.

13.72.

Footnote references are placed at the right in reading columns and symbol columns, and at the left in figure columns (also at the left of such words as None in figure columns), and are separated by a thin space.

13.73.

Two or more footnote references occurring together are separated by spaces, not commas.

13.74.

In a figure column, a footnote reference standing alone is set in parentheses and flushed right. In a reading column, it is set at the left in parentheses and is followed by leaders, but in the last column it is followed by a period, as if it were a word. In a symbol column it is set at the left and cleared.

13.75.

Numbered footnotes are placed immediately beneath the table. If a sign or letter reference in the heading of a table is to be followed, it is not changed to become the first numbered reference mark. The footnote to it precedes all other footnotes. The remaining footnotes in a table will follow this sequence: footnotes (numbers, letters, or symbols); Note.—; then Source:.

13.76.

For better makeup or appearance, footnotes may be placed at the end of a lengthy table. A line reading "Footnotes at end of table." is supplied.
