B physics results from e(+)e(-) annihilation at the Z(0) resonance are revi
ewed. A vast programme is summarized, including the study of B+, B-d(0), B-
s(0) and b baryon lifetimes, the time dependence of B-d(0)-(B) over bar (0)
(d) and B-s(0)-(B) over bar (0)(s) oscillations, the width difference in th
e B-s(0)-(B) over bar (0)(s) system, and the measurements of the magnitudes
of the CKM matrix elements V-cb and V-ub.
