Abstract
The current status of measurements of the nucleon
structure functions and their understanding is reviewed. The fixed
target experiments E665, CCFR and NMC and the HERA experiments H1 and
ZEUS are discussed in some detail. The extraction of parton momentum
distribution functions from global fits is described, with particular
attention paid to much improved information on the gluon momentum
distribution. The status of $\alpha_s$ measurements from deep
inelastic data is reviewed. Models and non-perturbative approaches for the
parton input distributions are outlined.
The impact on the phenomenology of QCD of the
data at very low values of the Bjorken $x$ variable is discussed in detail.
Recent advances in the understanding of the transition from deep
inelastic scattering to photoproduction are summarized. Some
brief comments are made on the recent HERA measurements of the ep NC and CC
cross-sections at very high $Q^2$.
