# Change multiple author reference from '&' to 'and' with natbib bibliography

I'd like to change the separation between multiple article/book authors from '&' to 'and' in natbib. eg:

@book{lee2009global,
title={{Global Marketing Management}},
author={Lee, K. and Carter, S.},
isbn={9780199239429},
lccn={2009005337},
year={2009},
publisher={Oxford University Press}
}


then:

\usepackage[longnamesfirst]{natbib}

\begin{document}
\bibpunct{(}{)}{;}{a}{,}{,}

\citep{lee2009global}


produces:

 (Lee & Carter, 2009)


I'd like it to produce:

 (Lee and Carter, 2009)

what bibliography style? –  Herbert Jan 9 '11 at 20:29
I've currently selected agsm, but it's not fixed. –  Martin KS Jan 10 '11 at 9:55

Put the following in your document preamble:

\AtBeginDocument{\renewcommand{\harvardand}{and}}


This is not a general solution for all .bst files, but it will work for any of the ones that are built into natbib.

For other .bst files, the solution may involve modifying the .bst file itself.

If you need a generic .bst file that fits your need you can make one using the makebst. (From a command line prompt, enter latex makebst).

Alternatively, if you are just beginning to use bibtex you should check out the biblatex package, which has many advantages over natbib with respect to your ability to tweak the output yourself.

Thanks that worked perfectly. –  Martin KS Jan 10 '11 at 17:24
