We present physics results obtained recently on the structure of the nucleon using lepton beams. The subjects discussed are: i) nucleon longitudinal spin structure with quark and gluon helicity measurements, ii) Semi-inclusive deep inelastic (SIDIS) results on hadron multiplicities for quark fragmentation function determination, iii) Transverse Momentum Dependent Distributions via SIDIS reactions and iv) Generalized Parton Distributions studies via Deep Virtual Compton Scattering and Meson Production. Data were taken at JLab (6 GeV electrons), HERMES (27 GeV electrons), and COMPASS (160/ 190 GeV muons).
