# Why does chapterbib include references from the entire document at the end of each chapter/section?

I'm making a document that has a bibliography at the end of each section and a global bibliography at the end. Logically, the bibliography at the end of each section should only contain citations that were referenced in that section. The global bibliography should contain every reference that is cited throughout the document. This is my code:

\documentclass[10pt]{article}

\usepackage{bibentry}
\usepackage[sectionbib]{chapterbib}
\usepackage{natbib}

\begin{document}

\bibliographystyle{plainnat}

\begin{cbunit}
\section{something}
First discuss \cite{goossens93}.

\bibliographystyle{plainnat}
\bibliography{mwecitations}
\end{cbunit}

\begin{cbunit}
\section{something else}
Now discuss \cite{rothstein2011unemployment} and \cite{fujita2010economic}.

\bibliographystyle{plainnat}
\bibliography{mwecitations}
\end{cbunit}

\renewcommand{\refname}{Global bibliography}
\bibliography{mwecitations}

\end{document}


This outputs:

The citations file mwecitations.bib is:

@book{goossens93,
author = "Frank Mittelbach and Michel Goossens  and Johannes Braams and David Carlisle  and Chris Rowley",
title = "The {LaTeX} Companion",
year = "1993",
}
@article{fujita2010economic,
title={Economic effects of the unemployment insurance benefit},
author={Fujita, Shigeru},
journal={FRB Phil. Business Review},
volume={4},
year={2010}
}
@article{rothstein2011unemployment,
title={Unemployment insurance and job search in the {Great Recession}},
author={Rothstein, Jesse},
journal={NBER},
volume={w17534},
year={2011}
}


Why are all citations from the entire document included in the bibliography that follows each section? The document should look like this (pardon my less-than-elegant edits).

I compile these files with Xelatex and Biblatex. From the documentation, I think I'm using cbunit correctly.

• Imho to get this working chapterbib would need separate files that you \include. You could try bibunits instead, but I would suggest to use biblatex/biber. – Ulrike Fischer Sep 1 '17 at 19:16
• @UlrikeFischer My interpretation of the documentation is that separate files aren't strictly necessary. From point 3: "Without \include: If you can’t use \include ... , then you can use \begin{cbunit} ... \end{cbunit} (for everything in one file)." Am I interpreting this incorrectly? – Michael A Sep 1 '17 at 19:26
• Imho the documenation is either wrong or misleading. But why don't you want to use biblatex? It is much more powerful, and such things work with refsegments directly. – Ulrike Fischer Sep 1 '17 at 20:17
• I just checked a work I have done with separate bibliography... I had to run bibtex in every chapter before runing in the main document. Checked that otherwise doesn't work. I will check it with your code too... may be the chaprers(sections) have to be seperated and just one bib file to be ok – koleygr Sep 1 '17 at 20:35
• @UlrikeFischer Sorry, I misread your first comment. You're saying that I could just use biblatex/biber/natbib together instead of chapterbib? I have no problems with that solution; I'm just not familiar with how biber works, but I'll look into it. – Michael A Sep 1 '17 at 20:35
