The following code produces a list of references that contains the URL three times. I use crossreferencing to save space. Is there a way to get rid of the URL in the entries that refere to a main entry?
\documentclass{article}
\usepackage{natbib}
\usepackage{url}
\begin{document}
\citet{Flickinger2008a,VanEynde2008a}
\bibliographystyle{plainnat}
\bibliography{test}
\end{document}
