# Two bibliographies with two different styles in the same document

When using biblatex, suppose I have set up two separate bibliographies, how can I assign them different styles, e.g. one numbered and the other author-year format or some such thing.

\documentclass{article}

\usepackage[defernumbers=true]{biblatex}

\DeclareBibliographyCategory{cited}

\usepackage{filecontents}

\begin{filecontents}{\jobname.bib}
@misc{A01,
author = {Author, A.},
year = {2001},
title = {Alpha},
}

@misc{B02,
author = {Buthor, B.},
year = {2002},
title = {Bravo},
}

@misc{C03,
author = {Cuthor, C.},
year = {2003},
title = {Charlie},
}
\end{filecontents}

\bibliography{\jobname}

\begin{document}

\nocite{*}

\cite{A01,B02}

\printbibliography[title={References},category=cited]

\end{document}

Good question. :-) One the one hand, section 3.6.2 of the biblatex manual mentions

mixing a numerical subbibliography with one or more subbibliographies using a different scheme (e. g., author-title or author-year).

On the other hand, according to section 3.1.1, style, bibstyle and citestyle are load-time options, i.e. they must be specified when biblatex is loaded and cannot be used in the optional argument of \printbibliography.

I have a possibly hackish solution. Load biblatex with a numeric style (the default behaviour) or an alphabetic style. Define a new bibliography environment nolabelbib that simply copies the definition of bibliography as found in authortitle.bbx and authoryear.bbx (i.e. one that doesn't print a label). Switch to this environment for your "Further Reading" (sub-)bibliography. The result should equate the authortitle style.

\documentclass{article}

\usepackage{biblatex}

\DeclareBibliographyCategory{cited}

% The following definition is copied from authortitle.bbx/authoryear.bbx
\defbibenvironment{nolabelbib}
{\list
{}
{\setlength{\leftmargin}{\bibhang}%
\setlength{\itemindent}{-\leftmargin}%
\setlength{\itemsep}{\bibitemsep}%
\setlength{\parsep}{\bibparsep}}}
{\endlist}
{\item}

\usepackage{filecontents}

\begin{filecontents}{\jobname.bib}
@misc{A01,
author = {Author, A.},
year = {2001},
title = {Alpha},
}
@misc{B02,
author = {Buthor, B.},
year = {2002},
title = {Bravo},
}
@misc{C03,
author = {Cuthor, C.},
year = {2003},
title = {Charlie},
}
\end{filecontents}

\nocite{*}

\begin{document}

Some text \autocite{A01,B02}.

\printbibliography[title={References},category=cited]


I've tried to compile this example with pdflatex file.tex bibtex file pdflatex file.tex pdflatex file.tex But no bibliography was generated. How could I compile correctly the example? Thanks. – jackb Sep 6 '13 at 10:19
