This article reviews the physics of deep-inelastic lepton-hadron processes in the region of small {ital x}, where {ital x} is the Bjorken scaling variable. The theoretical concepts concerning the Regge limit of deep-inelastic scattering are summarized and recent theoretical results on the small-{ital x} limit of parton distributions in perturbative QCD are discussed. Presently available experimental data on the free- and bound-nucleon structure functions at small {ital x} are reviewed in detail and their theoretical interpretations (including the low-{ital x}, low-{ital Q}{sup 2} region) are discussed. QCD predictions are given for the deep-inelastic scattering structure functions {ital F}{sub 2} and {ital F}{sub {ital L}} in the small-{ital x} (10{sup {minus}5}{lt}{ital x}{lt}10{sup {minus}2}) and moderately large-{ital Q}{sup 2} region relevant for HERA ({ital Q}{sup 2}{similar to}10 GeV{sup 2}).
