Long bibliographies in beamer

By default, Beamer displays the bibliography in such a way that authors, titles and journals are on three different lines. This may easily make the bibliography occupy more than one slide; in that case, the frame should be passed the allowframebreaks option, so that the full bibliography is split in different slides.

The following code shows the issues we may face with long bibliographies

% One slide bibliography
\documentclass{beamer}

% Theme choice
\usetheme{AnnArbor}

\begin{document}

% Add bibliography frame
\begin{frame}{References} 
    \nocite{*}
    \bibliographystyle{unsrt}
    \bibliography{MyReferences}
\end{frame}

\end{document}

As you can remark, some references do not appear. To remedy this issue, we can add the option [allowframebreaks] to the frame in question to get multiple slides. Check the modified code:

% Multiple slides bibliography
\documentclass{beamer}

% Theme choice
\usetheme{AnnArbor}

\begin{document}

% Add bibliography frame
\begin{frame}[allowframebreaks]{References} 
    \nocite{*}
    \bibliographystyle{unsrt}
    \bibliography{MyReferences}
\end{frame}

\end{document}

which yields to the following two slides:

In the above code, we used \nocite{*} to print all references in the file MyReferences.bib .
