The antibracket formalism for gauge theories, at both the classical an
d quantum level, is reviewed. Gauge transformations and the associated
gauge structure are analyzed in detail. The basic concepts involved i
n the antibracket formalism are elucidated. Gauge-fixing, quantum effe
cts, and anomalies within the field-antifield formalism are developed.
The concepts, issues and constructions are illustrated using eight ga
uge-theory models.
