# How can I create a bibliography like a section?

I have the following:

 \documentclass{article}
\usepackage{multicol}

\begin{document}
\begin{multicols}{2}

\section{}
\begin{thebibliography}{99}

\subsection{Differentiation}

\bibitem{DifIntWiki}
\emph{URL}

\end{thebibliography}
\end{multicols}
\end{document}


It creates a section with a number, and the Bibliography follows on the next line. I'm interested in combining these two lines together, essentially turning the bibliography into a section. Is there any way to do this?

Additionally, I'm using the multicol package, so I'm wondering if there is a way to do this without affecting the columns.

It's very similar to the question here: tex.stackexchange.com/questions/6637/how-to-number-the-toc the solution there might be used, just with \section instead of \chapter. Or use the tocbibind package. – Stefan Kottwitz Dec 8 '10 at 20:39
@Stefan: To adapt the answer you pointed to, one would also have to know about \refname. – lockstep Dec 8 '10 at 21:00

\usepackage{etoolbox}

and remove \section{} in the text.
I'm not sure if using the \subsection command within the thebibliography environment causes adverse effects. Also, please clarify "without affecting the columns".
@Matt: If the bibliography heading should be part of the first column, then my hack will suffice. But see Stefan's comment - especially consider to use a package like tocbibind. – lockstep Dec 8 '10 at 20:51
