At the Fermilab Tevatron energies, (s​=1800 GeV and s​=630
GeV), jet production is the dominant process. During the period 1992-1996, the
D0 and CDF experiments accumulated almost 100 pb**-1 of data and performed the
most accurate jet production measurements up to this date. These measurements
and the NLO-QCD theoretical predictions calculated during the last decade, have
improved our understanding of QCD, our knowledge of the proton structure, and
pushed the limit to the scale associated with quark compositeness to 2.4-2.7
TeV. In this paper, we present the most recent published and preliminary
measurements on jet production and fragmentation by the D0 and CDF
collaborations.Comment: 11 pages, 16 figures, Physics in Collisions Conference 2000 (Lisbon,
