I can't find why my bibliography in my beamer does not show a numeric citation, but this paper symbol... Any help? Thanks biblio photo
\usepackage[backend=biber,style=numeric, citestyle=ieee]{biblatex}
\addbibresource{ref.bib} %Imports bibliography file
\section{Bibliographie}
\begin{frame}[t,allowframebreaks]
\frametitle{Bibliographie}
\printbibliography[heading=none]
%\bibliography{ref}
\end{frame}
About a year ago I made some changes to automatically show the biblabel for numeric biblatex styles (21cf3d). So with beamer v3.58 or newer you don't have to do anything:
\documentclass{beamer}
\usepackage[backend=biber,style=numeric, citestyle=ieee]{biblatex}
\addbibresource{biblatex-examples.bib} %Imports bibliography file
\begin{document}
\section{Bibliographie}
\begin{frame}[t,allowframebreaks]
\frametitle{Bibliographie}
\nocite{knuth:ct}
\printbibliography[heading=none]
\end{frame}
\end{document}
If you have an older version, you need to switch this on manually:
\documentclass{beamer}
\usepackage[backend=biber,style=numeric, citestyle=ieee]{biblatex}
\addbibresource{biblatex-examples.bib} %Imports bibliography file
\setbeamertemplate{bibliography item}{\insertbiblabel}
\begin{document}
\section{Bibliographie}
\begin{frame}[t,allowframebreaks]
\frametitle{Bibliographie}
\nocite{knuth:ct}
\printbibliography[heading=none]
\end{frame}
\end{document}
