BibTeX, biblatex and biber ⇒ natbib not showing [first author] et. al.

[Mark4483]

Hello,

I just tried to change my citation style using natbib. From what I've read, using \citet{key} should show up as First Author et. al. (year) if there are mutilple authors. However, mine is listing all the authors instead. I would rather the et al. be there with more than one author. I've put together a simple example:

bibtex file:

Code: Select all

@book{rosen:2006,
    AUTHOR = {Marcus, Michael B. and Rosen, Jay},
     TITLE = {Markov processes, {G}aussian processes, and local times},
    SERIES = {Cambridge Studies in Advanced Mathematics},
    VOLUME = {100},
 PUBLISHER = {Cambridge University Press},
   ADDRESS = {Cambridge},
      YEAR = {2006},
}

Tex file:

Code: Select all

 
\documentclass{article}
\usepackage{natbib}

\begin{document}

\citet{rosen:2006}

\bibliographystyle{plainnat}
\bibliography{bibfile}

\end{document}
 

This produces "Marcus and Rosen [2006]" instead of "Marcus et al. [2006]".

How do I fix this? Thanks!

With two authors, you'll get both names. "et al." is used with three or more.
