  The generalized Baldin sum rule at finite four-momentum transfer Q^2 is
evaluated utilizing a structure function parameterization fit to recent
experimental data. The most recent measurements on F_1 from Hall C at Jlab, as
well as the F_2 structure function data from Hall B at Jlab and SLAC, were used
in constructing our parameterization. We find that at Q^2 below 1 GeV^2 the
dominant contribution to the electric and magnetic polarizabilities of the
nucleon comes from the resonance region.
