  I discuss the present situation with regard to a variety of theoretical
topics in hadronic spin physics: (a) global analysis of the g1
data---positivity at leading and next-to-leading order, renormalisation-scheme
dependence, parametrisation, and hyperon beta-decays; (b) items from the realm
of transverse spin---twist-three effects, single-spin asymmetries, and
transversity; and finally (c) recent developments in understanding the Q^2
evolution of orbital angular momentum.
