  We present a review of BaBar results on e+e- annihilations into exclusive
hadronic final states using the initial state radiation technique. Cross
sections over the sqrt{s} range from threshold to 4.5 GeV, with very small
point-to-point systematic errors, are presented for the 3pi, 2(pi+ pi-), 3(pi+
pi-), 2(pi+ pi-)2pi0, K+ K- pi+ pi-, 2(K+ K-) and p anti-p final states. The
proton form factor and the ratio of its electric and magnetic components are
also presented.
