One of the most intriguing puzzles in hadron spectroscopy are the numerous charmonium-like states observed in the last decade, including charged states that are manifestly exotic. Over the years, the experiment BABAR has extensively studied those in B meson decays, initial state radiation processes and two photon reactions. We report in this paper new and additional studies on some of those states, performed using the entire data sample collected by BABAR in e+e− collisions, at center of mass energies near 10.58 GeV/c2. Among these, the study of the process B → J/ψϕK, with a search for the resonant states X(4140) and X(4270) in their decays to J/ψϕ, will be highlighted. The recent BABAR results of the Dalitz analysis of ηc to 3 pseudoscalar mesons, via 2-photon interactions, will be also presented in this report. Preliminary results on χbJ in the field of bottomonium spectroscopy will be introduced.
