Biblatex IEEE extra comma before and: author1, author2, and author3

Question

When I use Biblatex with style=ieee, I get a COMMA and a AND before the third author in my bibliography:

MWE:

\documentclass{article}
\usepackage[english]{babel}
\usepackage[backend=bibtex,style=ieee]{biblatex} 
\begin{filecontents}{\jobname.bib}
@article{doe2015,
author={Doe1, J. and Doe2 K. and Doe3 L.},
title={Why I get this extra comma before the 'and' ?}
}
\end{filecontents}
\addbibresource{\jobname.bib}
\begin{document}
Citation here: \cite{doe2015}
\printbibliography
\end{document}

Produces:

Where is this listed as IEEE style?

My question is: how to fix (remove) the last comma before the "and"?

Also, I think this is not following IEEE anyway:

This: http://www.ieee.org/documents/ieeecitationref.pdf

is mentioning:

three or more authors: J. K. Author et al.

Why is this not implemented? Where can I find the "official" IEEE citation guidelines which is implemented by Biblatex/IEEE?

How can I enable this mode to list only the first author?

Answer 1

It is enough to modify the value of \finalandcomma:

\documentclass{article}
\usepackage[english]{babel}
\usepackage{filecontents}
\usepackage[backend=bibtex,style=ieee]{biblatex}
\begin{filecontents}{\jobname.bib}
@article{doe2015,
author={Doe1, J. and Doe2 K. and Doe3 L.},
title={Why I get this extra comma before the 'and'?},
year = 2015
}
\end{filecontents}

\addbibresource{\jobname.bib}
\AtBeginBibliography{\renewcommand\finalandcomma{}}

\begin{document}

Citation here: \cite{doe2015}
\printbibliography

\end{document} 

As mentioned by @moewe, a nicer way, instead of \AtBeginBibliography{…} is to write \DefineBibliographyExtras{english}{\let\finalandcomma=\empty}.

Answer 2

The implementation in biblatex-ieee follows as far as possible that in ieeetran. The latter describes itself as being official correct, so this is a reasonable reference point.

On the specific point about the 'Oxford comma' here, if you look at texdoc ieeetran and for example ref. 20 you will see

C. Barratt, M. C. Grant, and D. Carlisle.

with a comma. This is the reason that this is implemented as part of biblatex-ieee.

If you wish to override the behaviour, adding

\ExecuteBibliographyOptions{
  maxnames = 2,
  minnames = 1,
}

after loading biblatex will truncate the author list.

Answer 3

You've written the authors' names incorrectly and Bibtex is confused.

If you put the surname first followed by the initial you have to put a comma behind each surname: author={Doe1, J. and Doe2, K. and Doe3, L.},

Alternatively you could put initials first and then surnames, in which case no commas are needed: author={J. Doe1 and K. Doe2 and L. Doe3},
