Book excerpt: This report discusses a number of interesting hadronic spin effects which test fundamental features of perturbative and non-perturbative QCD. These include constraints on the shape and normalization of the polarized quark and gluon structure functions of the proton; the principle of hadron helicity retention in high x[sub F] inclusive reactions; predictions based on total hadron helicity conservation in high momentum transfer exclusive reactions; the dependence of nuclear structure functions and shadowing on virtual photon polarization; and general constraints on the magnetic moment of hadrons. I also will discuss the implications of several measurements which are in striking conflict with leading-twist perturbative QCD predictions, such as the extraordinarily large spin correlation A[sub NN] observed in large angle proton-proton scattering, the anomalously large [rho][pi] branching ratio of the J/[psi], and the rapidly changing polarization dependence of both J/[psi] and continuum lepton pair hadroproduction observed at large x[sub F].
