bibliography in "letter" class?

[Una Smith]

\documentclass{letter}
\usepackage{apacite}
...
\begin{document}
\begin{letter}{...}

\citeA{George1996} ...

\bibliographystyle{apacite}
\bibliography{my-bib-file}

\end{letter}
\end{document}

...seems to work, except LaTeX complains that \section (used by
apacite) is undefined.

What should I do to include a bibliography as part of a letter?

I asked:

>What should I do to include a bibliography as part of a letter?

...using the apacite package, version 1994/11/30? Well, I modified
the definition of the \thebibliography command in apacite.sty, so
LaTeX would know what to do when \section is not defined (as is the
case in "letter" class documents). Here is the revised definition:

\def\thebibliography#1{%
\@ifundefined{chapter}%
{\@ifundefined{section}%
{\vspace{.25in}\textbf{\refname}}%
{\section*{\refname}%
\@mkboth{\uppercase{\refname}}{\uppercase{\refname}}%
\addcontentsline{toc}{section}{\refname}}}%
{\chapter*{\bibname}%
\@mkboth{\uppercase{\bibname}}{\uppercase{\bibname}}%
\addcontentsline{toc}{chapter}{\bibname}}%
\list{\relax}{\labelsep=0em%
\leftmargin=\bibleftmargin%
\itemindent=-\bibleftmargin}
\def\newblock{\hskip .11em plus .33em minus .07em}
\sloppy\clubpenalty4000\widowpenalty4000
\sfcode`\.=1000\relax
}
