Although Bohr's Correspondence Principle (CP) played a central role in the firstdays of quantum mechanics, its original version seems to have no present-day relevance. The purpose of this article is to show that the CP, with no need of being interpreted in terms of the quantum-to-classical limit, still plays a relevant role in the understanding of the relationships between the classical and the quantum domains. In particular, it will be argued that a generic version of the CP is very helpful in elucidating the physical meaning of the phenomenon of quantum decoherence.
