BibTeX, biblatex and biber ⇒ natbib | Not always 'et al.', but sometimes full Author List

[Lasor]

Hi,

I've been having a problem that some of my citations come out with a full author list instead of Author et. al (year). If I use \citet{G06}, \citet{G07} in the text, the first one comes out properly but the second one gives the full author list (see entries below). It happens with other citations as well but there doesn't seem to be a pattern.

The preamble stuff I am using is

Code: Select all

\usepackage[round]{natbib}
\bibliography{refs}        %use a bibtex bibliography file refs.bib
\bibliographystyle{dcu}  %use the plain bibliography style

Code: Select all

@article{G07,
   Author = {Georg, R. B. and Halliday, A. N. and Schauble, E. A. and Reynolds, B. C.},
   Title = {Silicon in the {Earth's} core},
   Journal = {Nature},
   Volume = {447},
   Number = {7148},
   Pages = {1102-1106},
   Year = {2007}
}

@article{G06,
   Author = {Georg, R. B. and Reynolds, B. C. and Frank, M. and Halliday, A. N.},
   Title = {New sample preparation techniques for the determination of {S}i isotopic compositions using {MC-ICPMS}},
   Journal = {Chemical Geology},
   Volume = {235},
   Number = {1-2},
   Pages = {95-104},
   Year = {2006}
}

Any suggestions/solutions?

Somehow I can't reproduce the problem.

Code: Select all

\begin{filecontents*}{\jobname.bib}
@article{G07,
   Author = {Georg, R. B. and Halliday, A. N. and Schauble, E. A. and Reynolds, B. C.},
   Title = {Silicon in the {Earth's} core},
   Journal = {Nature},
   Volume = {447},
   Number = {7148},
   Pages = {1102-1106},
   Year = {2007}
}

@article{G06,
   Author = {Georg, R. B. and Reynolds, B. C. and Frank, M. and Halliday, A. N.},
   Title = {New sample preparation techniques for the determination of {S}i isotopic compositions using {MC-ICPMS}},
   Journal = {Chemical Geology},
   Volume = {235},
   Number = {1-2},
   Pages = {95-104},
   Year = {2006}
} 
\end{filecontents*}
\documentclass[11pt]{article}
\usepackage[T1]{fontenc}
\usepackage[round]{natbib}

\bibliographystyle{dcu}

\begin{document}
  \cite{G06}

  \cite{G07}
  \bibliography{\jobname}
\end{document}

So you will have to submit a proper minimal example that clearly shows the misbehaviour.

I found the problem to be that for some of my references with duplicate authors and years, natbib would not default to yeara and yearb but instead would print out the whoel list of names. I am still not sure why it only affected some author+years combinations but I have found a work around of manually adding a or b in the bibtex file.
