I would like to ask about the inverse of this Question if you please.
In other words: Using BibTeX, how to cite references in the context (showing author's name) without having the bibliography at the end the document?
For example
\documentclass{beamer}
\begin{document}
text ..........
text...... \cite{patygore}
\bibliographystyle{plainnat}
\bibliography{biblio}
\end{document}
