Multiple footnotes at one point

Question

I'm trying to create multiple footnotes referencing from one point, that look like this:

lorem^1,2

Searching for "multiple footnotes" shows up almost exclusively solutions for multiple references to one footnote. Here I have two separate footnotes, pointing from one place. I also don't want to merge them into one, because I tried it and it looks ugly.

Currently I resolved it in a quick and dirty way, writing:

lorem\footnote{foot1}$^{,}$\footnote{foot2}

Which shows up in the resulting PDF just fine, but I feel somehow bad about it. Is there a better way to do it?

Answer 1

Use the footmisc package and its multiple option.

\documentclass{article}

\usepackage[multiple]{footmisc}

\textheight=80pt% only for the example

\begin{document}

Some text.\footnote{A footnote}\footnote{And another one.}

\end{document}

Answer 2

This (the footmisc solution) won't work if you also have the hyperref package loaded. Either turn off hyperfootnotes [hyperfootnotes=false] as an argument to hyperref, or use \textsuperscript{,}. This maintains the same font for the comma, whereas your workaround above inserts the math font, and it could be different.

Answer 3

Additionally to the mentioned footmisc and the solution “by hand” there are three more possibilities.

1. The KOMA-Script classes offer the option footnotes=multiple:

   \documentclass{scrartcl}
   \KOMAoption{footnotes}{multiple}
   \textheight=50pt % for this example only
   \begin{document}
   Text\footnote{One}\footnote{Two}
   \end{document}
   

   

   As this again is not compatible with hyperref KOMA-Script also offers the rather lengthy \multiplefootnoteseparator. The comma used in both cases is set by \multfootsep which is defined through

   \newcommand*\multfootsep{,}
   

2. The memoir class natively supports multiple footnotes:

   \documentclass{memoir}
   \textheight=50pt % for this example only
   \begin{document}
   Text\footnote{One}\footnote{Two}
   \end{document}
   

   

   Again this is not working together with hyperref so memoir also defines a macro for manual input, \multfootsep, which is defined like this:

   \newcommand*{\multfootsep}{\textsuperscript{\normalfont,}}
   

3. Then there is fnpct - a package that was designed to offer a solution for the kerning between footnote marks and punctuation. As a sideeffect it also enables multiple footnotes that are compatiple with hyperref:

   \documentclass{article}
   \usepackage{fnpct}
   \usepackage[colorlinks]{hyperref}
   \textheight=50pt % for this example only
   \begin{document}
   Text\footnote{One}\footnote{Two}
   \end{document}
   

   

Answer 4

Here is a very easy way to implement it for oneself with only four lines of code. One can redefine the footnote-command and have a look to the following command using \futurelet. If the next command is also a footnote-command a , is included. That's all. And it plays well with the hyperref-package.

\documentclass{article}
\usepackage{hyperref}

\let\oldFootnote\footnote
\newcommand\nextToken\relax

\renewcommand\footnote[1]{%
    \oldFootnote{#1}\futurelet\nextToken\isFootnote}

\newcommand\isFootnote{%
    \ifx\footnote\nextToken\textsuperscript{,}\fi}

\textheight=3cm
\begin{document}

Text\footnote{First footnote}\footnote{Second footnote}\footnote{Third footnote} Text\footnote{Fourth footnote} Text

\end{document} 

Answer 5

you could also use an apostrophe written in math-mode for that:

\newcommand{\hochkomma}{$^{,}$}

For Example:

Testing multiple footnotes with commas \footnote{foonote1}\hochkomma\footnote{foonote2}\hochkomma\footnote{foonote3}

It will look like:
