  We report on the first measurement of the rapidity distribution dsigma/dy
over nearly the entire kinematic region of rapidity for e+e- pairs in the
Z-boson region of 66<M_ee<116 GeV/c2 and at higher mass M_ee>116 GeV/c2. The
data sample consists of 108 pb-1 of pbar-p collisions at sqrt{s}=1.8 TeV taken
by the Collider Detector at Fermilab during 1992--1995. The total cross section
in the Z-boson region is measured to be 252 +- 11 pb. The measured total cross
section and dsigma/dy are compared with quantum chromodynamics calculations in
leading and higher orders.
