# How to split bibliography into "works cited" and "works not cited"?

I need two bib-like sections: a "References" giving works explicitly cited in my text, and a "Bibliography" (or "Further reading" if you prefer) giving everything from my bibfile that didn't already appear in "References". The first is of course completely standard, but the second... I'm stumped.

Further loose constraints: I'm somewhat committed to biblatex and the biblatex-apa style. But I'll happily accept an answer not related to them if there's any chance I can adapt it.

• After a quick look, I think both of these will be easy with the more well-known bits of biblatex. The tricky bit is the cited/not-cited distinction, which biblatex apparently solves very elegantly (see lockstep's answer below). Dec 14, 2010 at 8:56

One learns something new about biblatex every day. :-)

\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}

\nocite{*}

\begin{document}

Some text \autocite{A01,B02}.

\printbibliography[category=cited]% default title for article class: "References"

\end{document}


• I'm speechless... after seeing this, I think my New Year's resolution will be to fully convert to biblatex. Dec 12, 2010 at 20:32
• That's awesome, thanks lockstep! @Willie Wong: biblatex has just hit v1.0, so your timing is perfect ^_^ It would be my answer to the questions you linked above too. Dec 14, 2010 at 8:38
• @lockstep, How to renumber the reference of "Futher Reading"? like [1] C.Cuthor…… Nov 5, 2011 at 12:24
• @PigCry: \printbibliography[title={Further Reading},notcategory=cited,resetnumbers=true]  Nov 5, 2011 at 17:56
• @PigCry Why would you want any reference numbers in the Further Reading list if you're not referencing them in the main text?

This is just a subtle difference from the @lockstep's solution, which enables you to put subtitles on each sub-list besides the main title.

% create a list of cited and uncited refereces with biblatex

\documentclass[12pt]{article}

% biblatex
\usepackage[backend=bibtex, sorting=none, style=numeric-comp, defernumbers=true]{biblatex} % using biblatex
% for each cited reference create a category named "cited"
\DeclareBibliographyCategory{cited}

\begin{document}

This one is cited \cite{jiao2013characterization}.

\nocite{*}

\end{document}


refs.bib might be something like this

@article{jiao2013characterization,
title={Characterization of high-latitude ionospheric scintillation of GPS signals},
author={Jiao, Yu and Morton, Yu T and Taylor, Steven and Pelgrum, Wouter},
volume={48},
number={6},
pages={698--708},
year={2013},
publisher={AGU}
}

@article{linty2018detection,
title={Detection of GNSS ionospheric scintillations based on machine learning decision tree},
author={Linty, Nicola and Farasin, Alessandro and Favenza, Alfredo and Dovis, Fabio},
