The charge asymmetry as a function of lepton rapidity, A(yl), has been measured at {radical}s = 1.8 TeV for {vert_bar}yl{vert_bar} < 1.8, using the W decays to electrons and muons recorded by CDF during the 1992--1993 run of the Tevatron Collider. The luminosity used, approximately 20 pb{sup {minus}1}, and detector improvements have lead to a six fold increase in statistics making discrimination between sets of parton distributions possible. Our data favors the most recent parton distributions and demonstrates the value of collider data in the measurement of the proton`s structure. In addition, the Drell-Yan cross section has been measured using 4.13 pb{sup {minus}1} of dielectron and 2.77 pb{sup {minus}1} of dimuon data taken during the 1988--1989 run. These measurements probe the quark distributions to x < 0.01 at high Q{sup 2} where nonperturbative effects are minimal.
