LaTeX.org

the \citet command was what I am looking for. Thanks for that. But since I have to use a certain bibliography style (\bibliographystyle{angewchem}) which uses numbers instead of author year. I get author is undefined in citation Bibliographygoogle.

Sorry for that
\documentclass[12pt,a4paper,draft]{scrartcl}
\usepackage[super,square,comma,sort&compress]{natbib}
\begin{document}
\section{Speed of light}
The speed of light is 300000kms$^{-1}.$\cite{Bibliographygoogle}
For further details see reference \ref{Bibliographygoogle}.
\bibliography ...

I like to reference a citation.
normally I do c=300000km/s\cite{google}
which returns c=300000km/s^{\[X\]}
but now I want to write somethich like: For further information see reference X
How can I do that
thank you for your help
