Apacite with natbibapa option change "and" in the references with ampersand

Question

I am using apacite with natbibapa option \usepackage[natbibapa]{apacite} in my latex document. At the moment, when I use \cite, the authors are delimited by "and". I want that to be changed to \& instead.

For example, I want to go from this referencing style:

Gilfoil and Jobs (2012) to Gilfoil & Jobs (2012)

I looked at this question: Using “and” instead of ampersand in natbib in-text citations (“\citet”) but this questions is only about the natbib package and is the opposite of what I want.

Any ideas of where to look? I also searched the documentation on apacite here: http://mirrors.ctan.org/biblio/bibtex/contrib/apacite/apacite.pdf but did not find something related to my question

Answer 1

The delimiter between the two names is saved in the two apacite macros \BBAA and \BBAB. Their default definitions are

\newcommand{\BBAA}{\&}  % between authors in parenthetical cites and ref. list
\newcommand{\BBAB}{and} % between authors in in-text citation

You can redefine them as you see fit. But you have to do that in \AtBeginDocument since apacite reacts to the document language and changes those settings in \AtBeginDocument.

\documentclass[british]{article}
\usepackage[T1]{fontenc}
\usepackage[utf8]{inputenc}
\usepackage{babel}
\usepackage{csquotes}

\usepackage[natbibapa]{apacite}

\AtBeginDocument{%
  \renewcommand{\BBAB}{\&}%
}

\usepackage{filecontents}
\begin{filecontents}{\jobname.bib}
@book{appleby,
  author  = {Humphrey Appleby and James Hacker},
  title   = {On the Importance of the Civil Service},
  year    = {1980},
}
\end{filecontents}


\begin{document}
\citet{appleby} \citep{appleby}
\bibliographystyle{apacite}
\bibliography{\jobname}
\end{document}
