  An overview of the SMC data taking and the polarized deep inelastic
scattering experiment is given. The new data on the deuteron extend the
kinematic range and have considerably reduced statistical and systematic
errors. The evaluation of the first moment of the spin dependent structure
function is presented and the result for the Bjorken sum rule from SMC data
alone is given. The spin contribution of the quarks to the spin of the nucleon
is obtained with information from weak decays of baryons. In a new polarized
semi-inclusive analysis the asymmetry of the difference between the number of
positive and negative charged hadrons was studied. Preliminary results are
shown.
