generally the references are kept at the last slide and cited using \cite command. I feel that this kind of notation is little difficult to understand from the point of an audience. Mostly, I use \footnote command, because it shows the reference at footer in same slide, which makes easier to understand. But \footnote can't print from bib file and therefore I always ended up putting one complete reference with \footnote. See below an example-
\documentclass{beamer}
\usetheme{Madrid}
\usepackage{bibentry}
\title[Test]{Test}
\author{Author}
\institute[]{Institute}
\date{\today}
\begin{document}
\begin{frame}{Citation}
This statement requires citation \cite{tobin1964commercial}
But the way I want is \footnote{Tobin, James. Commercial banks as creators of" money.". Cowles Foundation for Research in Economics at Yale University, 1964.} %\footnote{tobin1964commercial}
\end{frame}
\begin{frame}{References}
\bibliographystyle{amsalpha}
\bibliography{bibfile}
\end{frame}
\end{document}
This is how the generated PDF looks-

What I want is a way, so that I can use \footnote together with \cite command, something like \footnote{tobin1964commercial}. And this should show the complete reference in the footer.

This is BibTeX, Version 0.99d (TeX Live 2015) The top-level auxiliary file: ppt.aux I found no \citation commands---while reading file ppt.aux I found no \bibdata command---while reading file ppt.aux I found no \bibstyle command---while reading file ppt.aux (There were 3 error messages)– ravi Nov 20 '16 at 15:11biblatexthis has to be compiles withbiberand notbibtex. If you don't havebiberyou can try with\usepackage[style=verbose,backend=bibtex]{biblatex}instead. If you witch from bibtex to biber it is easiest to remove all the axillary files and compile from clean. – samcarter_is_at_topanswers.xyz Nov 20 '16 at 15:14Texmaker 4.5withTexlive 2015onUbuntu 14.04 x86_64OS.
