"Heavy Quarkonia and the Exotics"*

Heavy Quarkonia, charmonium and bottomonium are ideally suited for 
providing insight into quark-antiquark interactions. The knowledge of 
the spectra of the bound states of both systems is now essentially 
complete, thanks to the recent identification of the long elusive 
spin-singlet states by the CLEO detector at Cornell, and the Belle and 
BaBar detectors at the B-factories. A review of these experimental 
developments and their understanding in terms of pQCD based potential 
models and lattice calculations will be presented. The new challenges 
now relate to the unexpected states being observed above the break-up 
thresholds. The status of these so-called "exotics" will also be discussed.*
