# 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). –  Tikitu Dec 14 '10 at 8:56

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

\documentclass{article}

\usepackage[defernumbers=true]{biblatex}

\DeclareBibliographyCategory{cited}
\AtEveryCitekey{\addtocategory{cited}{\thefield{entrykey}}}

\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}

\addbibresource{\jobname.bib}

\nocite{*}

\begin{document}

Some text \autocite{A01,B02}.

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

\printbibliography[title={Further Reading},notcategory=cited]

\end{document}

I'm speechless... after seeing this, I think my New Year's resolution will be to fully convert to biblatex. –  Willie Wong Dec 12 '10 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. –  Tikitu Dec 14 '10 at 8:38
That is pretty awesome. –  Seamus Dec 14 '10 at 12:19
@lockstep, How to renumber the reference of "Futher Reading"? like [1] C.Cuthor…… –  Pig Cry Nov 5 '11 at 12:24
@PigCry: \printbibliography[title={Further Reading},notcategory=cited,resetnumbers=true]  –  lockstep Nov 5 '11 at 17:56
