# Remove column break before bibliography

I am writing a document using the ACM SIG Procedings template whose summarized structure is as follows (it uses 2 columns). I am using PDFLatex and Bibtex.

\documentclass{sig-alternate-2013}
\usepackage{hyperref}
....
\begin{document}

\section{Introduction}
\input{intro}

\section{Related work}
\input{relatedwork}
....

\section{Conclusion}
\input{conclusion}

\bibliographystyle{abbrv}
\bibliography{bib}
\end{document}


The conclusion section starts at the penultimate page. Then comes the bibliography which for some reason inserts a column break making the references section start in the right column and require an extra page. How can remove this column break? I have googled intensively searching for a solution but I have not found anything related. Is it "thebibliography" command that by default inserts this column break?

• This does not happend by default. What is in the conclusion file? – Andrew Swann Aug 25 '13 at 12:58
• There's nothing in the definition of thebibliography that suggests a column break; a space is missing after a constant 0, but it doesn't really make any harm. There is a bad error in the definition, but it may cause the exact contrary of your situation, namely that the title is at the bottom of a column and the references follow on the next one. – egreg Aug 25 '13 at 13:19
When you're using columns, \pagebreak opens up to the next column, which is not necessarily the next page. To get to the next page, regardless of what column you're currently in, you need to use something like \clearpage.
