[Tex/LaTex] Why does chapterbib include references from the entire document at the end of each chapter/section

bibliographieschapterbib

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:

Output document from this MWE

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",
    publisher = "Addison-Wesley",
    address = "Reading, Massachusetts"
}
@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).

Desired output from this MWE

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

Best Answer

Sorry, cbunit grouping doesn't facilitate using bibtex; it is only useful for manually compiled bibliographies. The documentation is rather cryptic on the point, but hints at it.

To use bibtex and have no page breaks between the bib groupings, you should use \cbinput, with with groupings in separate files. Be sure to run it according to the instructions (item 3): use the [draft] option (package or document); run latex; run bibtex on each file that was \cbinput; remove the [draft] option and run latex.

The [draft] option basically uses \include instead of \input so that separate .aux files get generated for bibtex to use.
