Something that has been annoying me for a while is getting the bibliography to display correctly at the end of a latex beamer presentation, i.e. across multiple slides rather than off the bottom.

Found this online today which fixes the problem,

\begin{frame}[allowframebreaks]
        \frametitle{References}
        \bibliographystyle{xxx}
        \bibliography{yyy.bib}
\end{frame}
