Query: Threshold Resummation and the Total Cross Section for Top Quark
  Production   We discuss the motivation for resummation of the effects of initial-state
soft-gluon radiation, to all orders in the strong coupling strength, for
processes in which the near-threshold region in the partonic subenergy is
important. We summarize our calculation of the total cross section for top
quark production at hadron colliders. Comments are included on the differences
between our treatment of subleading logarithmic terms and other methods.
