[Tex/LaTex] \cite and \footnote in together in Beamer

beamerbibtex

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.

\footcite might be a solution for you:

\documentclass{beamer}

\setbeamertemplate{navigation symbols}{}

% only for this example, otherwise in .bib file
\usepackage{filecontents}

\begin{filecontents}{\jobname.bib}
@TECHREPORT{RePEc:cwl:cwldpp:159,
    title = {Commercial Banks as Creators of 'Money'},
    author = {Tobin, James},
    year = {1963},
    institution = {Cowles Foundation for Research in Economics, Yale University},
    type = {Cowles Foundation Discussion Papers},
    number = {159},
    url = {http://EconPapers.repec.org/RePEc:cwl:cwldpp:159}
}
\end{filecontents}

\usepackage[style=verbose,backend=biber]{biblatex}
\addbibresource{\jobname.bib}

\begin{document}
 \begin{frame}
    Text text \footcite{RePEc:cwl:cwldpp:159}
 \end{frame}

 \begin{frame}
     \printbibliography
 \end{frame} 

\end{document}

[Tex/LaTex] Using `easybmat` and `beamer` together

I've already encountered this bug once. Here are two solutions to solve the problem; the first is quick and easy to put in place, while the second needs to look at where the problem occurs.

SOLUTION 1. It is possible to load packages before \documentclass by using \RequirePackage instead of \usepackage. This allows to get both etex and easybmat loaded before tikz and makes the problem disappear:

\RequirePackage{etex}
\RequirePackage{easybmat}
\documentclass[beamer]{beamer}
\begin{document}
test
\end{document}

SOLUTION 2. Loading easybmat first and then etex cannot work because there won't be enough dimen registers available for easybmat. So you must load etex first and easybmat second. The error message becomes You can't use a prefix with '\begingroup'. The reason for this error is due to both easybmat.sty and etex.sty. The problem with easybmat.sty is that it calls the package easy.sty which declares some new dimensions with \global\newdimen. Putting a \global before \newdimen is not necessary but is usually harmless. Here, however, it is not harmless because etex.sty is loaded and (the two conditions must be met) the \newdimen with the \global occurs when etex.sty switches between the vanilla TeX registers and the extended eTeX engine ones. The reason can be found in the code of the \alloc@ macro from etex.sty which has a \begingroup in it. What happens is that the \global before \newdimen gets applied to this \begingroup, thus triggering the error. A (not very elegant) way to solve the problem is to put a dummy definition just before the \begingroup. It should not (I hope) have any side effects.

\documentclass[beamer]{beamer}

\usepackage{etex}
\makeatletter
\def\alloc@#1#2#3#4#5%
 {\ifnum\count1#1<#4% make sure there's still room
    \allocationnumber\count1#1
    \global\advance\count1#1\@ne
    \global#3#5\allocationnumber
    \wlog{\string#5=\string#2\the\allocationnumber}%
  \else\ifnum#1<6
    \def\etex@dummy@definition{}% <-- code added
    \begingroup \escapechar\m@ne
    \expandafter\alloc@@\expandafter{\string#2}#5%
  \else\errmessage{No room for a new #2}\fi\fi
 }
\makeatother
\usepackage{easybmat}

[Tex/LaTex] References at the end of beamer slides

If you are using natbib for references, then you can use the bibentry package to create references in footnotes. It should be noted that this is a bit of a hack, and it doesn't really implement a proper footnote reference style, but emulates one. To deal with subsequent citations (as you request in the comments) I've created a second command \secondcite which will place a footnote referencing the correct citation's original footnote number without duplicating the bibliography entry itself. Here's an example:

\documentclass{beamer}

\begin{filecontents}{\jobname.bib}
@book{Saussure1995,
    Author = {Ferdinand de Saussure},
    Origyear = {1916},
    Publisher = {Payot},
    Title = {Cours de Linguistique G{\'e}n{\'e}rale},
    Year = {1995}}

@book{Labov1972,
    Address = {Philadelphia},
    Author = {William Labov},
    Publisher = {University of Pennsylvania Press},
    Title = {Sociolinguistic Patterns},
    Year = {1972}}

\end{filecontents}
\usetheme{Montpellier}
\usepackage{natbib}
\usepackage{bibentry}
\bibliographystyle{apalike}
\usepackage{chngcntr}

\counterwithin*{footnote}{page}
\newcommand\footcite[1]{\footnote{\bibentry{#1}}\label{\thepage:#1}}
\newcommand\secondcite[1]{\textsuperscript{\ref{\thepage:#1}}}

\begin{document}
\nobibliography{\jobname}
\begin{frame}

  \frametitle{Stuff famous linguists asked}
  \begin{block}{A block}
       \begin{enumerate}
        \item Is it part of \emph{langue} or part of \emph{parole}?\footcite{Saussure1995}
        \item Is it socially stratified?\footcite{Labov1972}
        \item More Saussure\secondcite{Saussure1995}
       \end{enumerate}
  \end{block}
\end{frame}
% The next frame is a duplicate for testing purposes    
\begin{frame}

  \frametitle{Stuff famous linguists asked}
  \begin{block}{A block}
       \begin{enumerate}
        \item Is it part of \emph{langue} or part of \emph{parole}?\footcite{Saussure1995}
        \item Is it socially stratified?\footcite{Labov1972}
        \item More Saussure\secondcite{Saussure1995}
       \end{enumerate}
  \end{block}
\end{frame}


\end{document}

output of code

If you want the references to be one big frame, then using [allowframebreaks] is the way to go. I find the standard formatting of references in beamer overly garish, so I subdue everything:

\setbeamercolor*{bibliography entry title}{fg=black}
\setbeamercolor*{bibliography entry author}{fg=black}
\setbeamercolor*{bibliography entry location}{fg=black}
\setbeamercolor*{bibliography entry note}{fg=black}
\setbeamertemplate{bibliography item}{}

I also allow for the "(cont.)" to be used on subsequent slides:

\setbeamertemplate{frametitle continuation}[from second]

The references slide itself is simple.

\begin{frame}[t,allowframebreaks]
\frametitle{References}
\bibliography{<bibfile>}
\end{frame}
\end{document}
