List reference by author

Question

I am trying to use this code to order my references by author. I am on TeXworks and I am using Biber at the moment.I want to list all refernces with the author Weber in it.

\documentclass{article}
\usepackage[T1]{fontenc}
\usepackage[french]{babel}
\usepackage[style=alphabetic,maxnames=6,natbib=true,backend=biber]{biblatex}
%\bibliography{biblatex-examples}
\addbibresource{bibpractice.bib}

\begin{document}
\DeclareSourcemap{
  \maps[datatype=bibtex]{
    \map{
      \step[fieldsource=author,
            match=Weber,
            final]
      \step[fieldset=keywords, fieldvalue=weber]
    }
  }
}

\printbibliography[keyword=weber]
\printbibliography[notkeyword=weber]
\end{document}

This is the error I get:

INFO - This is Biber 2.7 INFO - Logfile is 'biberpractice.blg' ERROR - Cannot find control file 'biberpractice.bcf'! - did you pass the "backend=biber" option to BibLaTeX? INFO - ERRORS: 1

Answer 1

Your MWE is almost there. \DeclareSourcemap should go into the preamble.

Here we filter out citations authored by Knuth and Sigfridsson. Note that you have to \cite or \nocite{*} all the entries you want to consider for filtering.

\documentclass{article}
\usepackage[T1]{fontenc}
\usepackage[french]{babel}
\usepackage[style=alphabetic, maxnames=6, natbib=true, backend=biber]{biblatex}
\addbibresource{biblatex-examples.bib}

\DeclareSourcemap{
  \maps[datatype=bibtex]{
    \map{
      \step[fieldsource=author,
            match=Knuth,
            final]
      \step[fieldset=keywords, fieldvalue=knuth]
    }
    \map{
      \step[fieldsource=author,
            match=Sigfridsson,
            final]
      \step[fieldset=keywords, fieldvalue=sigfridsson]
    }
  }
}

\begin{document}
\nocite{sigfridsson,knuth:ct:a,companion,worman,knuth:ct:c}
\printbibliography[keyword=knuth]
\printbibliography[keyword=sigfridsson]
\printbibliography[notkeyword=knuth,notkeyword=sigfridsson]
\end{document}
