  In this paper we calculate Kolmogorov-Sinai entropy $h_M(S)$ of the
generalized Markov shift associated with a contractive Markov system (CMS)
\cite{Wer1} using the coding map constructed in \cite{Wer3}. We show that
\[h_M(S)=-\sum\limits_{e\in E}\int\limits_{K_{i(e)}} p_e\log p_ed\mu\] where
$\mu$ is a unique invariant Borel probability measure of the CMS. I. Werner,
