Abstract
The measurements of the spin structure functions for the proton and neutron are reviewed. Recent high-precision data have allowed the Bjorken sum rule to be verified to within ca. 10% accuracy, providing a rigorous test of qu antum chromodynamics, the current theory of strong interactions. The data s how that there is a deficit between the spin carried by the quarks and the spin of the nucleon, as measured in deep-inelastic scattering. The theories of the deficit are discussed.
