  To obtain improved parton densities of the proton, we present a new global
analysis of deep-inelastic and related hard scattering data including, in
particular, the recent measurements of F2 at HERA, of the asymmetry of the
rapidity distributions of W+- production at the FNAL pbar p collider and of the
asymmetry in Drell-Yan production in pp and pn collisions. We discuss the
evolution of the new partons to low values of Q2.
