# Wrong level in TOC for bibliography with sectionbib and memoir

I have a document using the memoir class, and I use the bibunits package to produce chapterwise bibliographies. This produces bibliographies as sections in each chapter, as expected, but in the table of contents, the bibliographies appear as chapters. I would like them to appear as sections there as well. How can I do this?

Here is a minimum working example:

\documentclass{memoir}
\usepackage[sectionbib]{bibunits}

\begin{document}

\bibliographyunit[\chapter]

\tableofcontents

\chapter{First chapter}
\section{First section}
This is the first chapter with one citation \cite{alonso1992phy}.
\putbib[references]

\end{document}


where the references.bib file is

@book{alonso1992phy,
author = {Alonso, Marcelo and Finn, Edward J.},
title = {Physics},
year = {1992}
}


• Apparently, bibunit does not take care of memoir settings. If you use book as class, there would be no entry in the ToC at all, by default. – user31729 Mar 30 '16 at 9:50

The memoir class has by default \bibsection defined being \@memb@bchap, an starred chapter which is added to the ToC if \bibintoc is used.

Redefining \bibsection to use \@memb@bsec is only a partial workaround, since this would add a numbered section as bibliography unit. A slight redefinition of \@memb@bsec takes care about this and will use either \section* or \section, depending on the state of \ifnumberedbib.

\documentclass{memoir}

\makeatletter

\newif\ifnumberedbib
\numberedbibfalse % False by default anyway

\AtBeginDocument{%
\renewcommand{\@memb@bsec}{%
\ifnumberedbib
\section{\bibname}
\else
\section*{\bibname}%
\fi
\bibmark
\ifnobibintoc\else
\ifnumberedbib\else
\phantomsection
\fi
\fi
\prebibhook
}

\renewcommand{\bibsection}{\@memb@bsec}
}

\makeatother
\usepackage[numbers]{natbib}
\usepackage[sectionbib]{bibunits}

\begin{document}

\bibliographyunit[\chapter]

\tableofcontents

\chapter{First chapter}
\section{First section}
This is the first chapter with one citation \cite{alonso1992phy}
\putbib[larsreferences]

\section{Second section}
This is the first chapter with one citation \cite{alonso1992phy}
\end{document}

• One should note that for the real document there's a global bibliography -- the memoir settings for this usual bibliography should be saved before and restored later on. – user31729 Mar 30 '16 at 10:11
• Thanks! That's great, and definitely solves the basic problem. However, I now see that I made my example a little too minimal, because ideally I would like to use this in combination with the natbib package with the numbers option, and that does not work. Do you have any idea why? – Lars Eirik Bø Mar 30 '16 at 11:16
• @LarsEirikBø: You're complicating the situation. I'll have a look later on – user31729 Mar 30 '16 at 11:21
• @LarsEirikBø: See the update -- the culprit is (again ;-)) memoir which does some redefinitions for natbib in a \AtBeginDocument{...} hook. I wrapped another \AtBeginDocument{...} around the changes from the original version and it seems to work. However, there might be other natbib conditions that are not fit. – user31729 Mar 30 '16 at 11:46
