  Standard Model predictions for neutrino-electron scattering cross-sections,
including effects of electroweak radiative corrections, are reviewed. The
sensitivity of those quantities to neutrino dipole moments, z' bosons,
dynamical symmetry breaking and other types of ``New Physics'' is described.
Neutrino indices of refraction in matter are also discussed. A perspective on
future initiatives with intense neutrino sources, such as superbeams and
neutrino factories, is given.
