  We report a new measurement of the pseudorapidity (eta) and transverse-energy
(Et) dependence of the inclusive jet production cross section in pbar b
collisions at sqrt(s) = 1.8 TeV using 95 pb**-1 of data collected with the
DZero detector at the Fermilab Tevatron. The differential cross section
d^2sigma/dEt deta is presented up to |eta| = 3, significantly extending
previous measurements. The results are in good overall agreement with
next-to-leading order predictions from QCD and indicate a preference for
certain parton distribution functions.
