  We present calculations of next-to-leading order and resummed QCD corrections
for semi-inclusive deep-inelastic scattering and single-inclusive e+e-
annihilation. The resummation is performed to next-to-leading logarithmic
accuracy. Knowing these QCD corrections is important in order to extract parton
distribution functions and fragmentation functions from present and future data
for these reactions. We present comparisons of our results to recent data by
the COMPASS, HERMES, Belle, and BaBar experiments.
