Suppress printing of only \bibentry references with natbib?

Question

This question was basically asked before, but I think that the only answer didn't quite understand the question so I thought I'd try again. I'm writing a paper in which I need to have references show up in two places: a special list of "key references" in its own section, and a bibliography containing the rest of the references that were cited in the text. I thought that bibentry would do it, so the document looks something like:

\documentclass[11pt]{article}
\usepackage{natbib}
\usepackage{bibentry}
\nobibliography*
\begin{document}
\section{Amazing idea}
Chicken chicken chicken \citep{chicken:2010fj}.  Chicken chicken, chicken \citep{turkey:2010jk}.
\section{Key References}
\begin{enumerate}
\item \bibentry{lemur:2009ii}
\item \bibentry{gibbon:2011jk}
\end{enumerate}
\bibliographystyle{apalike}
\bibliography{amazing.bib}
\end{document}

Unfortunately, this doesn't quite do it, as the resulting document presents the lemur and gibbon bibentry references correctly in the "Key References" section, but also prints them in the bibliography at the end of the document. Ideally, the only entries in the bibliography would be the chicken and turkey \citep references. I'd like it to look like:

Key references

1. Lemur, L. (2009). Lemur, 12(4):1-7.
2. Gibbon, G. (2011). Gibbon, 135:1002-1009.

References

Chicken, C. (2010). Chicken. Chicken Press, Coop.

Turkey, T. (2010). Turkey, 7(4):E231.

What it actually looks like:

Key references

1. Lemur, L. (2009). Lemur, 12(4):1-7.
2. Gibbon, G. (2011). Gibbon, 135:1002-1009.

References

Chicken, C. (2010). Chicken. Chicken Press, Coop.

Gibbon, G. (2011). Gibbon, 135:1002-1009.

Lemur, L. (2009). Lemur, 12(4):1-7.

Turkey, T. (2010). Turkey, 7(4):E231.

Is there any way to achieve this with the current method, or is there some other (possibly easier!?) way to do this?

Answer 1

As stated in the answer to the other question bibentry is not suitable for the task at hand (without modifications). If you want to give biblatex a try, it is easy to set it up for what you want to achieve.

\documentclass{article}
\usepackage[utf8]{inputenc}
\usepackage{filecontents}
\usepackage{csquotes} 
\usepackage[natbib,style=authoryear]{biblatex}


\begin{filecontents}{\jobname.bib} 
@article{nature, 
   author      =   {Rosa Rademakers and Manuela Neumann and Ian R. Mackenzie}, 
   title      =   {Advances in understanding the molecular basis of frontotemporal dementia - elongated title}, 
   journal      =   {Nature Reviews Neurology}, 
   volume      =   {8}, 
   year      =   {2012}, 
   pages      =   {423-434}, 
   doi         =   {10.1038/nrneurol.2012.117}} 
@article{fuente, 
   author      =   {D. de la Fuente and J.G. Castaño and M. Morcillo}, 
   title      =   {Long-term atmospheric corrosion of zinc}, 
   journal      =   {Corrosion Science}, 
   volume      =   {49}, 
   year      =   {2007}, 
   pages      =   {1420-1436},
   url = {www.elsevier.com/locate/corsci},
   } 
 @incollection{Rocca2007a,
   author = {Rocca, Emmanuel and Mirambet, Fran\c{c}ois},
   booktitle = {Corrosion of Metallic Heritage Artefacts: Investigation, Conservation and Prediction of Long Term Behaviour},
   chapter = {18},
   editor = {Philippe Dillmann and Pedro Piccardo and Gerard Beranger},
   pages = {308-334},
   title = {{Corrosion inhibitors for metallic artefacts: temporary protection}},
   year = {2007}}
\end{filecontents} 

\addbibresource{\jobname.bib}

\DeclareBibliographyCategory{keyreferences}

\defbibenvironment{keyrefs}
  {\begin{enumerate}}
  {\end{enumerate}}
  {\item}

\begin{document} 
Test \citet{nature}\addtocategory{keyreferences}{nature}

another test \cite{fuente} and \citep{Rocca2007a}

\printbibliography[env=keyrefs,category=keyreferences,title={Key References}]
\printbibliography[notcategory=keyreferences]
\end{document} 

The key issue is to create a category for the key references. After that we can use the category and notcategory options to \printbibliography command to filter the references. Also the natbib option allows us to use standard natbib commands for citations.

Since you want the key references to be printed as an enumerate list, we can use the command \defbibenviornment to use enumerate as the wrapper environment for them, and use the env=... option to specify it.

Answer 2

This is an old question, however it may be useful to have a BibTeX-only solution. Using multibib and bibentry together this is relatively simple: define and show an additional bibliography (here: q) for the normal references (use \citeq, citepq, etc.) and show the key references as bibentry while suppressing the list for these references with \nobibliography. multibib is compatible with natbib. Compile sequence:

pdflatex mbib.tex
bibtex q
bibtex mbib
pdflatex mbib
pdflatex mbib

MWE:

mbib.tex

\documentclass[11pt]{article}
\usepackage{natbib}
\usepackage{multibib}
\newcites{q}{References}
\usepackage{bibentry}
\nobibliography*
\begin{document}
\section{Amazing idea}
Chicken chicken chicken \citepq{chicken:2010fj}.  Chicken chicken, chicken \citepq{turkey:2010jk}.
\section*{Key references}
\begin{enumerate}
\item \bibentry{lemur:2009ii}.
\item \bibentry{gibbon:2011jk}.
\end{enumerate}
\bibliographystyleq{apalike}
\bibliographyq{mbibref.bib}
\bibliographystyle{apalike}
\nobibliography{mbibref.bib}
\end{document}

mbibref.bib

@book{chicken:2010fj,
    author = {Chicken, C},
    title = {Chicken},
    publisher = {Chicken Press},
    year = {2010}
}
@book{turkey:2010jk,
    author = {Turkey, T},
    title = {Turkey},
    publisher = {Turkey Press},
    year = {2010}
}
@book{lemur:2009ii,
    author = {Lemur, L},
    title = {Lemur},
    publisher = {Lemur Press},
    year = {2009}
}
@book{gibbon:2011jk,
    author = {Gibbon, G},
    title = {Gibbon},
    publisher = {Gibbon Press},
    year = {2011}
}

If you don't want to change \citep to \citepq in an existing document then you can copy the definition of \citepq into \citep and keep using the original command name in the document.

However, because \citepq uses \citep internally you should first store the original definition in a helper command like \origcitep and use that in the new definition.

Relevant code snippet:

\usepackage{natbib}
\usepackage{multibib}
\newcites{q}{References}
\makeatletter
\let\origcitep\citep
\def\citep{\let \@citex \mb@@citex \let \@newciteauxhandle \@auxoutq \csname origcitep\endcsname}
\makeatother
\usepackage{bibentry}
\nobibliography*
\begin{document}
\section{Amazing idea}
Chicken chicken chicken \citep{chicken:2010fj}.  Chicken chicken, chicken \citep{turkey:2010jk}.

Similarly you can redefine \citet and \cite as well.
