# Remove the 'and' between the last and second last authors in biblatex?

I'm trying to make my biblatex references match this Vancouver style guide. After some tweaking, my biblatex references are almost exactly how I want them, with one exception. The word and is inserted between the last and second last authors.

How can I remove the word 'and' between the last and second last authors?

Here is a MWE:

\documentclass{article}

% nejm style gets us close.
\usepackage[style=nejm, terseinits=true]{bib latex}

% This bit makes sure the last names come before the initials.
\DeclareNameAlias{default}{last-first}
\renewcommand*{\revsdnamepunct}{}

% This puts the volume number in parentheses.
\renewbibmacro*{volume+number+eid}{%
\printfield{volume}%
\printfield{number}%
\printfield{eid}}
\DeclareFieldFormat[article]{number}{\mkbibparens{#1}}

\begin{filecontents}{references.bib}
@article{kenkre_simple_1997,
title = {Simple Solutions of the {{Torrey}}–{{Bloch}} Equations in the {{NMR}} Study of Molecular Diffusion},
volume = {128},
url = {http://www.sciencedirect.com/science/article/pii/S1090780797912167},
number = {1},
journaltitle = {J. Magn. Reson.},
author = {Kenkre, V. M. and Fukushima, Eiichi and Sheltraw, D.},
urldate = {2017-02-07},
date = {1997-06},
pages = {62--69},
}

\end{filecontents}

\begin{document}
Here is a reference \parencite{kenkre_simple_1997}.
\printbibliography
\end{document}


You can redefine \finalnamedelim, but note that it is language dependent. So you have to use \DeclareBibliographyExtras:

\documentclass{article}

% nejm style gets us close.
\usepackage[style=nejm, terseinits=true]{biblatex}

% This bit makes sure the last names come before the initials.
\DeclareNameAlias{default}{last-first}
\renewcommand*{\revsdnamepunct}{}

% This puts the volume number in parentheses.
\renewbibmacro*{volume+number+eid}{%
\printfield{volume}%
\printfield{number}%
\printfield{eid}}
\DeclareFieldFormat[article]{number}{\mkbibparens{#1}}

\DefineBibliographyExtras{english}{%

• @daviewales In this case is was simply reading/searching in the biblatex manual. May 27, 2017 at 10:28
• I've found all the puzzle pieces in the biblatex manual now using a text search, but I doubt I would have ever pieced them together myself! May 27, 2017 at 10:33
• @daviewales I do not say, that you should have find it. I only tell you, what I've done. But I already know, that biblatex has configuration features for almost everything. And I have some experience in using LaTeX (but not a lot in using biblatex). May 27, 2017 at 10:48
• I don't think it is \finalnamedelim that is language specific (expect for spanish.lbx). \finalandcomma which is used in \finalnamedelim is language specific. In your MWE the \DefineBibliographyExtras{english} is not needed. May 27, 2017 at 12:35
