We perform a global leading-order QCD fit to recent polarized structure function data in order to extract a consistent set of spin-dependent parton distributions. Assuming that there is no significant intrinsic polarization of the quark sea, the data are consistent with a modest amount of the proton's spin carried by the gluon, although the shape of the gluon distribution is not well constrained. We show how inelastic J/ψ production in polarized photon-hadron scattering can, in principle, provide definitive information on the shape of the gluon distribution.
