In this talk I review NRQCD predictions for the production of charmonium at
the Tevatron. After a quick presentation of the NRQCD factorization formalism
for production and decay I review some old results and discuss how they compare
to recent data. Following this I discuss some recent work done with Adam
Leibovich and Ira Rothstein.Comment: Invited talk: 9th International Symposium on Heavy Flavor Physic
