  I discuss recent results from Jefferson Lab on the measurement of inclusive
spin structure functions in the nucleon resonance region using polarized
electron beams and polarized targets. Results on the first moment of the spin
structure function for protons and neutrons are discussed, as well as the
Bjorken integral. I will argue that the helicity structure of individual
resonances plays a vital role in understanding the nucleon's spin response in
the domain of strong interaction QCD, and must be considered in any analysis of
the nucleon spin structure at low and intermediate photon virtuality.
