  Since the start of HERA operation there has been considerable progress in the
understanding of jet production in e p collisions. QCD calculations are now
able to accommodate the hadronic structure of the virtual photon. The
luminosities delivered by HERA are now sufficient to allow studies of final
states in which more than two high transverse energy jets are produced. The
transition between jet processes in photoproduction and in deep inelastic
scattering has been studied in some detail. These advances are highlighted
here.
