Recently, several charmonium-like states above DD threshold have been discovered at the BELLE and BABAR B-factories. Some of these states are produced via Initial State Radiation (\it e.g. Y(4260) and Y(4350)) and some are observed in B meson decays (\ite.g. X(3872), Y(3940)). The BELLE observation of the enhancement in the ψ(2S)π-, \it i.e. the Z(4430)- state, has generated a great deal of interest, because such a state must have minimum quark content (ccdu), so that it would represent the unequivocal manifestation of a four-quark meson state. Here we report recent BABAR results on the Y(4260), X(3872), Y(3940), and a search for the Z(4430)-.
