A search for charmonium and other new states is performed in a study of exclusive initial-state-radiation production of Ds+Ds-, Ds*+Ds-, and Ds*+Ds*- events from electron-positron annihilations at a center-of-mass energy of 10.58 GeV. The data sample corresponds to an integrated luminosity of 525 fb-1 recorded by the BaBar experiment at the PEP-II storage ring. We also study the decay width and the mass of the Ds1(2536) meson with high precision via the decay channel Ds1(2536)->D+* K0s using 384 fb-1 of data recorded by the BABAR experiment.
