Query: New Interactions in Neutral Current Processes   Measurements of neutral current processes off the $Z$-peak are sensitive
probes of new interactions, which may be induced by the exchange of new
particles such as leptoquarks or extra $Z$'s. This talk reviews the
phenomenology of extra interactions in four-fermion processes and updates a
global fit to contact terms in the neutral current sector.
