The BESIII experiment at the Beijing Electron Positron Collider (BEPCII)
collected about 13 fb-1 of data in the energy range 4.0 GeV~ 4.6 GeV
dedicated to the study of potentially exotic states in the charmonium region.
Vector resonances, such as the Y (4260), are studied in lineshape analyses of
various exclusive e+e- ->hadrons cross sections. Some of these reactions,
e.g., e+e--> gamma J/psi and e+e- -> pi pi J/psi among others, also boast
the possibility to explore intermediate X- and Z-like states through their
decays, for example in X(3872) -> pi+pi-J/psi or Zc (3900) -> pi J/psi.
An overview of recent results obtained with BESIII and an outlook on future
perspectives regarding exotic hadron studies will be given.
