Recent data on J/{psi}, {psi}(2S), {chi}{sub c} and {gamma} production has unraveled unexpected features of Q{bar Q} bound states production in high energy hadronic collisions. In the 1992-1995 runs CDF has collected large samples of J/{psi}, {psi}(2S) and {gamma} identified through their muonic decay. In the charmonium system all production sources have been separately measured and compared with the theoretical predictions. A large excess of direct production has been observed for both {psi}(2S) and J/{psi}. The relative production rate for the {chi}{sub c}{sup 1} and {chi}{sub c}{sup 2} has also been measured. Results on J/{psi}, {psi}(2S) and {chi}{sub c} production from the fixed target experiments E789,E705 and E672/706 are also presented. Important features of the production of charmonium states are shared by fixed target and collider data.
