Abstract

This paper reviews semileptonic decays of $B$-mesons to states containing charm mesons, i.e., D, D*, D** and possible non-resonant D^{(*)}npi states as well. The paper covers measurement of branching fractions, form-factors and, most importantly, the magnitude of the CKM matrix element V_cb.
