  We present a measurement of the Drell-Yan cross section at high dielectron
invariant mass using 120/pb of data collected in pbar-p collisions at sqrt(s) =
1.8 TeV by the D0 collaboration during 1992-96. No deviation from standard
model expectations is observed. We use the data to set limits on the energy
scale of quark-electron compositeness with common constituents. The 95%
confidence level lower limits on the compositeness scale vary between
  3.3 TeV and 6.1 TeV depending on the assumed form of the effective contact
interaction.
