Abstract
We review the current state of experimental knowledge on double ccbar production in e+e- annihilation. The large cross-sections (O(20 fb)) for e+e- -> gamma* -> psi(') ccbar_{res} processes have been confirmed by detailed tests and reproduced by a second group: they should now be considered well-established. The latest experimental results concern the case where the second ccbar system is above open-charm threshold: hidden-charm states continue to play a prominent role in the mass spectrum. Some ``loose ends'' in the field are also briefly discussed.
