    "abstract": "The Drell-Hearn-Gerasimov (DHG) sum rule relates the helicity structure of\nthe photoabsorption cross section to the anomalous magnetic moment of the\nnucleon. It is based on Lorentz and gauge invariance, crossing symmetry,\ncausality and unitarity. A generalized DHG sum rule my be derived for virtual\nphotons. At low momentum transfer this generalized sum rule is saturated by the\nresonance region, at high momentum transfer it may be expressed by the parton\nspin distributions measured in deep inelastic scattering. The\nlongitudinal-transverse interference determines the Cottingham sum rule, which\nis related to the electric and magnetic form factors over the whole range of\nmomentum transfer.",
