Page vs Column footnotes

The distinction between page and column footnotes can be subtle. This section will illustrate the key differences:

  • Page footnotes always appear in a single group at the bottom of the page. Column footnotes are emitted whenever a page type change is requested, even if the new type is the same as the old. So there could be two or more groups of column notes on a page, but only ever a single group of page notes.

  • Page footnotes span the width of the page (even under multi-column text), column footnotes are attached to the bottom of the column to which they refer. It is possible to specify double-column page notes, but they will still occupy a single block at the bottom of the page.

  • It is possible for a single column to have both column and page footnotes, in which case the page notes always come after the column footnotes. Usually in such cases the two types of notes are distinguished by using different formats, or a separator between the two groups.

  • The numbering of page and column footnotes is entirely independent. A change to one has no effect on the other.

For example, the following image represents a page with single column text (red) followed by some double column text (green and blue). The striped areas at the bottom of each column represent column footnotes, while the darker area at the bottom of the page contains the page footnotes. You will notice that the blue column has a number of column notes but no page notes at all.

The second diagram shows the same page but with double-column page footnotes. These can be used to save space if the text of the notes is normally very short. You can see that the page notes still appear in order, and that the column break in the page footnotes has nothing whatever to do with column breaks in the main text. See the Layout Editor Manual for instructions on how to enable double-column page footnotes.
