BibTeX, biblatex and biber ⇒ Place a character ahead of a list item

[kaiserkarl13]

Is there a general, robust way of adding a character to the beginning of all items in the (numbered) bibliography? What I'm looking for is something like

References
S1. Last, First. Title Volume (number): pages (year).
S2. Last2, First2. Title2 Volume2 (number2): pages (year).

This would be similar to redefining table and figures to be Table S1 and Figure S1, etc., which can be done by

Code: Select all

\renewcommand{\thetable}{S\arabic{table}}
\renewcommand{\thefigure}{S\arabic{figure}}

This would be very helpful when preparing references for supplementary information to a journal article (which prevents them from getting confused with the citations from the main text).

Thank you!

P.S. The specific document I'm using now uses the article class with the achemso package and associated BibTeX style.

Hi,

you could make a simple redefinition of the \@biblabel command as defined in the article class. The following code shows this approach:

Code: Select all

\documentclass{article}

\makeatletter
\renewenvironment{thebibliography}[1]
     {\section*{\refname}%
      \@mkboth{\MakeUppercase\refname}{\MakeUppercase\refname}%
      \list{\@biblabel{S\@arabic\c@enumiv}}%just add here the character "S"
           {\settowidth\labelwidth{\@biblabel{#1}}%
            \leftmargin\labelwidth
            \advance\leftmargin\labelsep
            \@openbib@code
            \usecounter{enumiv}%
            \let\p@enumiv\@empty
            \renewcommand\theenumiv{\@arabic\c@enumiv}}%
      \sloppy
      \clubpenalty4000
      \@clubpenalty \clubpenalty
      \widowpenalty4000%
      \sfcode`\.\@m}
     {\def\@noitemerr
       {\@latex@warning{Empty `thebibliography' environment}}%
      \endlist}
\makeatother

\begin{document}

\begin{thebibliography}{9}
  \bibitem{key1} test item1 
  \bibitem{key2} test item2 
  \bibitem{key3} test item3 
\end{thebibliography}

\end{document}

The thebibliography environment is internally a simple list. Try to redefine the label in the fourth level of that list right before inserting your bibliography section.

Code: Select all

\renewcommand\theenumiv{S\arabic{enumiv}}
