Formatting Information — An introduction to typesetting with LATEX

### Chapter 5: Textual tools

The command \footnote{Like this}, followed by the text of the footnote in curly braces, will produce an auto-numbered footnote with a raised small number where you put the command, and the numbered text automatically printed at the foot of the page. The number is reset to 1 at the start of each chapter (but there are packages to override that and make them run continuously throughout the document, or even restart at 1 on each page or section).

LATEX automatically creates room for the footnote, and automatically reformats it if you change your document in such a way that the point of attachment and the footnote would move to the next (or preceding) page.

### Verbatim inside footnotes

Because LATEX reads the whole footnote before doing anything with it, you can’t use the \verb (inline verbatim) command inside footnotes on its own: either use the \VerbatimFootnotes command from the fancyvrb package, or precede \footnote with \protect, or use (abuse?) the \url command instead (which you should be using for Web and email addresses in any case).

Footnotes in titling commands (\title, \author, etc) are generally regarded as Bad Style, and you should avoid them; if you can’t, they produce the symbols *, †, , §, , |, **, ††, and ‡‡ for the values 1–9 (and an error message for the tenth such footnote). In accordance with standard publishing practice, footnotes inside a minipage environment produce lettered notes instead of numbered ones, and they get printed at the bottom of the minipage, not the bottom of the physical page (but this too can be changed).

There is a package (endnote) to hold over your footnotes and make them print at the end of the chapter instead or at the end of the whole document, and there is a package (fnpara) to print many short footnotes in a single footnoted paragraph so they take up less space. It is also possible to have several separate series of footnotes active simultaneously, which is useful in critical editions or commentaries in the Humanities: for example, a numbered series for the original author’s original footnotes; a lettered series for footnotes by subsequent commentators or authorities in later editions; and a roman-numeral series for your own footnotes. It is also possible to format footnotes within footnotes.

If your footnotes are few and far between, you may want to use the sequence of footnote symbols above instead of numbers. You can do this by redefining the output of the footnote counter to be the \fnsymbol command (with the footnote as its argument):

```\renewcommand{\thefootnote{\fnsymbol{footnote}}
```

There are also ways to refer more than once to the same footnote, and to defer the positioning of the footnote if it occurs in a float like a Table or Figure, where it might otherwise need to move to a different page, but these techniques are out of scope here.
