### Environment thebibliography undefined when using letter

Greetings,
I am using the letter document class, and I want to include some citations. From what I have gathered the letter document class doesn't allow having bibliography items in the letter body. If that's the case, is there a workaround?
Here is the code that I am trying to run:

\documentclass{letter} \signature{} \begin{document}\begin{letter}{}  \begin{center}{} \end{center} \vfill  \opening{Dear} \closing{Sincerely yours,} \encl{}			\end{letter}\bibliographystyle{plain}\bibliography{bibdb}\end{document}

Latex Error: Environment thebibliography undefined.

The purpose of using a letter class and citations is because I want to write a cover letter and I need to refer to some citations inside of the letter's body.

Thank you,
h.

It's not quite so simple, as there are a number of things that must be defined to get the bibliography to work. I got it working with the following code copied from article.cls into a file "letterbib.sty" then the command \usepackage{letterbib} in the preamble:

This worked beautifully. Thanks so much! Maybe it's obvious, but I also had to load the natbib package:

\usepackage{letterbib}\usepackage{natbib}
