We present a search for the X(3872) produced in B-->psi pi+pi- K and B-->psi pi+pi-pi0 K (psi=J/psi or psi(2S)) using 427 fb-1 of BaBar data. We present updated mass and width measurements for the Y(4260)--> J/psi pi+pi- produced in Initial State Radiation events using 454 fb-1 of data. We report the study of the B meson decays B+--> J/psi phi K+ and B0--> J/psi phi K_S, and of charged and neutral B decays to chi_c1 K pi. We describe a detailed study of charmonium states produced in two-photon collisions and decaying to K_S K pi and K K pi pi pi0. We present a high statistics measurement of the mass and width of the etac(2S) state.
