# \bibentry generating error with chicago style

I am trying to use \bibentry (with natbib) to have the full reference appear in the text, based on the example here (and others). However, this is generating an error Paragraph ended before \citeauthoryear was complete.<to be read again>\par.

I don't have any \citeauthoryear style citations in my full document. I have tried removing packages and changing memoir to book, thinking it was an incompatibility. I have also tried the suggestion here to evade the error with \renewcommand{\citeauthoryear}{}.

This document generates the error:

\documentclass[12pt,a4paper]{memoir}

\usepackage{natbib}
\usepackage{bibentry}  % allows full ref text in body
\nobibliography*           % needed with bibentry

\title{TITLE}
\author{authors}
\date{}

\begin{document}
\maketitle

Want a full reference in the text here: \bibentry{Bunch2003}

and a normal reference \citep{Bunch2003}

\bibliographystyle{chicago}
\bibliography{mytestbib}

\end{document}


This is mytestbib contents:

@Article{Bunch2003,
Title                    = {{S}oft systems methodology and the ecosystem approach: {A} system study of the {C}ooum {R}iver and environs in {C}hennai, {I}ndia},
Author                   = {Bunch, M. J.},
Journal                  = {Environmental Management},
Year                     = {2003},
Number                   = {2},
Pages                    = {182-197},
Volume                   = {31}
}


Can anyone see what I am doing wrong?

UPDATE It appears the incompatibility is with the chicago bibstyle. The error disappears with apalike. Any guidance on how to fix it so I could continue to use chicago?

• Welcome to TeX.SE. I'm able to replicate the problem you report if I use the memoir document class, but not if I use the article class. It may be that there's an incompatibility between the memoir class and the bibentry package; however, I'm not sure at this point. – Mico Nov 22 '15 at 10:56
• I am getting it in the article class too. – JenB Nov 22 '15 at 11:07
• Imho chicago is not compatible with bibentry. It inserts \citeauthoryear in the optional argument of bibitem and this breaks when bibentry tries to read the bbl. Why don't you use biblatex instead of natbib? – Ulrike Fischer Nov 22 '15 at 11:35
• It seems to work if you add this before the \nobibliography: \makeatletter \renewcommand\BR@b@bibitem[2][]{\BR@bibitem[#1]{#2}\BR@c@bibitem{#2}} \makeatother . – Ulrike Fischer Nov 22 '15 at 11:43
• That fixed it thanks. If you want to write it as an answer, I can accept it. I should investigate biblatex, but I am really not that confident with LaTeX and natbib usually works for me. – JenB Nov 22 '15 at 14:22

 \makeatletter

before \nobibliography.
