  The electromagnetic form factors of hadrons at large momentum transfer have
been the subject of intense theoretical and experimental scrutiny over the past
two decades, yet there is still not a universally-accepted framework for their
description. This review is a synopsis of their current status at large
momentum transfer. The basic theoretical approaches to form factors at large
momentum transfer are developed, emphasizing the valence quark and Feynman
(soft) pictures. The discussion includes the relation of these descriptions to
the parton model, as well as the roles of factorization, evolution, Sudakov
resummation and QCD sum rules. This is followed by a discussion of the
experimental status of pion and nucleon elastic form factors and resonance
production amplitudes in the light of recent data, highlighting the successes
and shortcomings of various theoretical proposals.
