  We review angle resolved photoemission spectroscopy (ARPES) results on the
high Tc superconductors, focusing primarily on results obtained on the
quasi-two dimensional cuprate Bi2Sr2CaCu2O8 and its single layer counterpart
Bi2Sr2CuO6. The topics treated include the basics of photoemission and
methodologies for analyzing spectra, normal state electronic structure
including the Fermi surface, the superconducting energy gap, the normal state
pseudogap, and the electron self-energy as determined from photoemission
lineshapes.
