# Remove space in reference in "et al. ,"

I'm using Sharelatex to work on my thesis, and I want to use the natbib package and authordate3 style for my bibliography. For some reason, when referencing a bibliography entry with multiple authors, I get a space between "et al." and the year.

Here's a minimal example:

\documentclass{article}
\usepackage[utf8]{inputenc}
\usepackage{natbib}
\bibliographystyle{authordate3}

\begin{filecontents}{biblio.bib}
@book{jon99,
author          = "Tom Jones and
Jack Smith and
John Doe",
title           = "Wonderful Book",
year            = "1999"
}
\end{filecontents}

\begin{document}
\citep{jon99}

\bibliography{biblio.bib}

\end{document}


In Sharelatex, this gives:

Now, I've looked around, but the only solution that seems to work is by manipulating the authordate3.bst file (as suggested here), which I obviously don't have access to, since I don't have LaTeX installed on my machine.

I've also tried changing the punctuation separation between the author and the year to include \unskip using \setcitestyle{aysep={\unskip,}}, but that unfortunately didn't work. Simply adding a negative space (such as using \setcitestyle{aysep={\kern-ex1,}}) fixes the space for multiple references but places the comma on top of the author's name for single references.

• Note that authordate3.bst is not a good style for natbib. Feb 19 '15 at 11:34
• I can't reproduce that behavior. I don't have that space. As a side note note that it should be \bibliography{biblio} and not \bibliography{biblio.bib} Feb 19 '15 at 11:39
• @karlkoeller For me, the space is there. I can reproduce the problem.

• This should be reported as a bug to Nelson Beebe, the upstream authordate package appears to have been fixed but that has not propagated to the version in his collection which is used in texlive. Feb 19 '15 at 13:51

This is somewhat of a home cooked solution, but I opened the authordate3.bst file in my text editor and replaced the three occurrence of {\em et~al.\ } with {\em et~al.}. My authordate3.bst was located here /usr/local/texlive/2014/texmf-dist/bibtex/bst/beebe/authordate3.bst.
