I'm putting references at the bottom of Beamer slides. I'm referring to the same footnote twice in one slide, but latex is create a duplicate footnote: the label/ref is not working.

I found a version of this problem for natbib: References at the end of beamer slides However, I'm doing this in Biblatex as I need to format the citations.

How can I refer to the same footnote twice, but avoid having a duplicate footnote created? I need the counter to reset for each slide and start from 1 every frame. How can I reset the counter for every slide?



\newcommand{\customcite}[1]{(\citeauthor{#1}, \citeyear{#1})}
\newcommand{\customfootcite}[1]{\footnote{\citeauthor{#1} (\citeyear{#1}), \emph{\citetitle{#1}.} \citejournal{#1}}}

%\newcommand\secondcite[1]{\textsuperscript{\ref{\thepage:#1}}}%This worked in Natbib, but is commented out because I'm using Biblatex now. . .

\DeclareFieldFormat[article]{title}{\mkbibemph{#1}} %Removes quotiation marks, puts italics
\DeclareFieldFormat[article]{journaltitle}{#1} % italic journal title with comma


    \item Individual investor behaviour: Household finance
    \item Rationality in individual preference models vs behavioural finance
    \item Rational learning vs biased learning~\customcite{murray}~\customfootcite{murray}
    \item Learning by doing vs learning about ability~\customfootcite{murray}
    \item Experimental studies: immediate outcomes~\customfootcite{augustine} \& well-structured feedback~\customfootcite{cotton}
  • As defined, your \customfootcite command has no way of knowing anything other than that it should print the information you've told it to. If this is a one-time thing, I'd recommend simply using \footnote[<num>], where <num> is the number corresponding to to the footnote number that is created for the first use of \customfootcite{murray}. Otherwise you are going to need to invest time creating a more robust citation style for.

  • Is it possible, at least, to restart the counter for \customfootcite on each slide? Mar 15, 2014 at 10:12
  • 2
    My guess would be yes if you do: \usepackage{perpage} and \MakePerPage{footnote}; or \usepackage[perpage]{footmisc}. But I have never used either with beamer...

  • BTW: When should I use \input vs. \include? Apr 27, 2014 at 16:02
  • @jon \usepackage{perpage} \MakePerPage{footnote} works great in beamer. Thanks. Consider extending that an answer so I can upvote it? \usepackage[perpage]{footmisc} does not work in combination with biblatex and beamer, though idk what breaks it. Sep 11, 2015 at 3:51
