A search for charmonium and other new states is performed in a study of exclusive initial-state-radiation production of D (D) over bar events from electron-positron annihilations at a center-of-mass energy of 10.58 GeV. The data sample corresponds to an integrated luminosity of 384 fb(-1) and was recorded by the BABAR experiment at the PEP-II storage ring. The D (D) over bar mass spectrum shows clear evidence of the psi(3770) plus other structures near 3.9, 4.1, and 4.4 GeV/c(2). No evidence for Y(4260)-> D (D) over bar is observed, leading to an upper limit of B(Y(4260)-> D (D) over bar)/B(Y(4260)-> J/psi pi(+)pi(-))< 1.0 at 90% confidence level.
