Available in PDF, EPUB and Kindle. Book excerpt: We present an overview of the measurements for polarized electron scattering from polarized NH_3, ND_3, and ^3He targets at JLab. All three experimental halls are involved in this program. The data span a range in Q^2 up to about 3.5 GeV^2 and a range in the gamma*N invariant mass W up to 3.5 GeV. The photon absorption function A_1 and the spin structure function g1 for the proton and deuteron have been extracted from data obtained with the CLAS spectrometer. The photon absorption functions, A_1 and A_2, and the spin structure functions g_1 and g_2 for ^3He have been obtained from Hall A data.
