11.4 Symbolic footnotes

If you want to use symbols for footnotes, rather than increasing numbers, redefine \thefootnote like this:

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

The \fnsymbol command produces a predefined series of symbols (see \alph \Alph \arabic \roman \Roman \fnsymbol). If you want to use a different symbol as your footnote mark, you'll need to also redefine \@fnsymbol.
