# Chicago Manual-style footnote numbers

TeX

Here’s a first tip for humanist TeXheads.

The Chicago Manual of Style calls for footnote numbers that are not superscript and followed by a period. It’s really not that obvious how to do this in LaTeX, and it was many years before I learned how. Put this in your preamble:

```\makeatletter
\renewcommand\@makefntext[1]{%
\parindent 1em%
\@thefnmark.~#1}
\makeatother
```

See Mittlebach and Goosens’s LaTeX Companion, 112–14. Unlike the standard `\@makefntext`, this version does not put the footnote number in a `\makebox` hanging off the left margin of the footnote body. Many books also use different length rules between body and footnotes when a footnote continues from a previous page. For that, use the preamble command `\usepackage[splitrule]{footmisc}`. This invocation must precede the command that changes `\@makefntext`, or `footmisc` will clobber your nice formatting.

The code for altering endnotes (if you use the `endnote` package) is slightly different:

```\renewcommand\enoteformat{\parindent 1em\theenmark.~}
```

On the other hand, if you use the recently developed `biblatex-chicago` package, your footnotes will be correctly formatted—with more or less this very command. The package also has a `strict` option which will suppress the rule except for footnotes continued from a previous page (the *Manual*’s preferred style).
