  The heavy quarkonium c\bar{c} and b\bar{b} resonances have a rich
spectroscopy with numerous narrow S, P, and D-wave levels below the production
threshold of open charm and beauty mesons. The mass predictions for these
states are an important test of QCD calculations. We review some recent work
describing the production of missing \eta_b(nS), 1^3D_J(b\bar{b}) and
1^1P_1(c\bar{c}) and 1^1P_1(b\bar{b}) states.
