<h3>Footnotes in captions</h3>
<p/>Footnotes in captions are especially tricky: they present problems of
their own, on top of the problems one experiences with
<a href="FAQ-ftnsect.html">footnotes in section titles</a> and with
<a href="FAQ-footintab.html">footnotes in tables</a>. Fortunately, the
requirement for footnotes in captions is extremely rare: if you are
experiencing problems, it is worth reviewing what you are trying to
say by placing this footnote. Note that the <i>threeparttable</i>
scheme (see, again,
<a href="FAQ-footintab.html">footnotes in tables</a>) also applies
to notes in captions, and may very well be preferable to whatever you
were thinking of.
<p/>If you <em>are</em> going to proceed:
<ul>
<li> use an optional argument in your <code>\</code><code>caption</code> command, that
doesn’t have the footnote in it; this prevents the footnote
appearing in the “List of ...”, and
<li> put your whole float in a <code>minipage</code> so as to keep
the footnotes with the float.
</ul>
so we have:
<blockquote>
<pre>
\begin{figure}
\begin{minipage}{\textwidth}
...
\caption[Caption for LOF]%
{Real caption\footnote{blah}}
\end{minipage}
\end{figure}
</pre>
</blockquote><p>
However, <em>as well as</em> all of the above, one <em>also</em> has to
deal with the tendency of the <code>\</code><code>caption</code> command to produce the
footnote’s text twice. For this last problem, there is no tidy
solution this author is aware of.
<p/>If you’re suffering the problem, a well-constructed <code>\</code><code>caption</code>
command in a <code>minipage</code> environment within a float (as
in the example above) can produce <em>two</em> copies of the footnote
body “blah”. (In fact, the effect only occurs with captions that are
long enough to require two lines to be typeset, and so wouldn’t appear
with such a short caption.)
<p/>The documentation of the <i>ccaption</i> package describes a really
rather awful work-around.
