I am using beamer and I want the footnote in the PDF to be superscript like
But in the footer, I want it shown as
\documentclass{beamer}
\usepackage[style=authoryear]{biblatex}
% Redefine the @makefnmark command to add space between label and text
\makeatletter
\renewcommand{@makefnmark}{\hbox{\normalfont[@thefnmark]\enspace}}
\makeatother
% Change the font size for footnotes
\makeatletter
\renewcommand{\footnotesize}{\tiny}
\makeatother
\addbibresource{references.bib}
\begin{document}
\begin{frame}{Acknowledgments}
This is a citation\footfullcite{LenTayQui:J16}.
\end{frame}
\begin{frame}
\frametitle{References}
\printbibliography
\end{frame}
\end{document}



biblatex, we are lucky on this site to have experts so it helps people find your question if it is tagged appropriately :) – JamesT Jun 03 '23 at 08:10\footfullciteonly generates a footnote containing the full bibliography entry. The footnote number need not correspond to any citation label/number that is assigned for example by a numeric citation style. In particular several\footfullcitecalls to the same entry will generate different numbers. (This is not as obvious here since your style choice andbeamerusually don't number the bibliography at the end. But if there were numbers in the bibliography they could not be guaranteed to correspond to the footnote numbers at all.) – moewe Jun 03 '23 at 12:24
