Aspects of charged-current scattering including the question of whether the cross sections are ''anomalous'' in any sense and the subject of limits on the production of new heavy quarks are discussed. A new, unique determination of neutral-current couplings is discussed using data from deep-inelastic and elastic neutrino scatterings and from neutrino-induced exclusive and inclusive pion production. Charged-current couplings are treated in the context of the Weinberg-Salam (WS) theory of weak and electromagnetic interactions with the Glashow-Ilipoulos-Maiani (GIM) quark structure. (JFP)
