More than 40 years after the discovery of the J/psi, the first charmonium state to be seen in experiment, the spectroscopy of charmonium and charmonium-like system stills receives a great deal of attention both from theorists and experimentalists alike. The family of charmonium-like states includes states with large isospin-breaking effects in their decay and states whose minimal quark contents falls outside the conventional scheme of mesons and baryons. In this talk I will present a selection of results from the BESIII collaboration obtained in e+e- collisions with centre-of-mass energies around 4 GeV.
