We outline a coherent strategy for exploring the four remaining narrow charmonium states [η′c(21S0), hc(1^1P1), ηc2(1^1D2), and ψ2(1^3D2)] expected to lie below charm threshold. Produced in B-meson decays, these levels should be identifiable now via striking radiative transitions among charmonium levels and in exclusive final states of kaons and pions. Their production and decay rates will provide much needed new tests for theoretical descriptions of heavy quarkonia.
