  These lectures present the phenomenology of B meson decays and their impact
on our understanding of CP violation in the quark sector, with an emphasis on
measurements made at the e+e- B factories. Some of the relevant theoretical
ideas such as the Operator Product Expansion and Heavy Quark Symmetry are
introduced, and applications to the determination of CKM matrix elements given.
The phenomenon of B flavor oscillations is reviewed, and the mechanisms for and
current status of CP violation in the B system is given. The status of rare B
decays is also discussed.
