I am using Beamer with biblatex.

When I use the code below, it produces the following slide.

I would like to replace the tiny journal picture by [FC1] for the first category (then [FC2] for the second reference in the first category etc...) and [SC1] for the second category (then [SC2], etc...). Is it possible?

As pointed out in comment, the solution proposes in How do I get numbered entries in a beamer bibliography do not work here. If I use 

  \setbeamertemplate{bibliography item}{[\theenumiv]}

I get [0] in front of each article. If I use 

\setbeamertemplate{bibliography item}{\insertbiblabel}

I get nothing in front of each article. In addition, I would like to have FC or SC for my reference depending of the keyword of each article.

enter image description here

The code

\documentclass[10pt]{beamer}
\usepackage{beamerthemesplit} 
\usepackage[english,french]{babel}
\usepackage{xcolor} 
\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc} 
\usepackage[backend=bibtex,style=authoryear, defernumbers=true]{biblatex}
\addbibresource{bib.bib}
\usetheme{default}

\begin{document}

\begin{frame}
\begin{itemize}
\item First category
\nocite{*}
\printbibliography[prefixnumbers=FC, heading=none,keyword=fstcat]
\item Second category
\printbibliography[prefixnumbers=SC, heading=none,keyword=sndcat]
\end{itemize}
\end{frame}

\end{document}

The .bib file 

@article {test1,
AUTHOR = {LastName1, FirstName1},
TITLE = {A long title that says nothing interesting},
JOURNAL = {Big journal},
VOLUME = {1},
YEAR = {1111},
NUMBER = {1},
PAGES = {1--111},
keywords={fstcat}
 }

@article {test2,
AUTHOR = {LastName2, FirstName2},
TITLE = {A long title that says nothing interesting again},
JOURNAL = {Very Big journal},
VOLUME = {1},
YEAR = {1111},
NUMBER = {1},
PAGES = {1--111},
keywords={sndcat}
 }

  • Please ask only one question per question. That makes it easier for those answering your question and it enables others to find answers more quickly. – moewe Apr 21 '17 at 09:28
  • @TeXnician The solution proposes in the possible duplicate do not work here. And in addition, I want some extra information in each category. – user37238 Apr 21 '17 at 09:30
  • @user37238 Why does it not work (have you tried setting it in a biblatex-style)? Extra information can always be added as you use biblatex. – TeXnician Apr 21 '17 at 09:34
  • @TeXnician see my edit. – user37238 Apr 21 '17 at 09:34
  • With style=authoryear you won't get labels like 'FC2', you need to use style=numeric or similar. Note also that prefixnumber is no longer a valid option to \printbibliography the option is now called labelprefix and needs to be passed to a refcontext environment. – moewe Apr 21 '17 at 09:35
  • @moewe I seems to work. Thank you. I'm going to start another question for the color thing. – user37238 Apr 21 '17 at 09:37

You will only get labels in the bibliography if you use a style that provides them.

style=authoryear does not provide these sort of labels. You probably want

style=numeric

You will still need the \setbeamertemplate{bibliography item}{\insertbiblabel} from How do I get numbered entries in a beamer bibliography.

Note that in more recent versions of biblatex prefixnumber has been renamed to labelprefix and can no longer be given as an option to \printbibliography. You will need to use a refcontext (see here).
