Main issues we consider in this work include the polarization of prompt J/psi at the Fermilab Tevatron and the large relativistic and QCD corrections to double-charmonium production at the B factories. We also consider inclusive charm production in bottomonia decays.8 pages, talk given by Jungil Lee at The Eighth International Conference on Hyperons, Charm and Beauty Hadrons (BEACH 2008), Columbia, South Carolina, USA, June 22-28, 2008High Energy Physics - Phenomenologytext
