  We use all the available new precise data for deep inelastic and related hard
scattering processes to perform NLO global parton analyses. These new data
allow an improved determination of partons and, in particular, the inclusion of
the recent measurements of the structure functions at HERA and of the inclusive
jets at the Tevatron help to determine the gluon distribution and alpha_S
better than ever before. We find a somewhat smaller gluon at low x than
previous determinations and that alpha_S(M_Z^2) = 0.119 +/- 0.002 (expt.) +/-
0.003 (theory).
