We present measurements of inclusive charmonium production of charmonium in B decays and from the continuum, as well as exclusive branching ratios of B mesons into charmonium final states. We present also a measurement of the B0 -> K*0 gamma branching ratio and a search for the decay B0 -> gamma gamma.4 pages, 7 postscript figures Conference proceedings for XXXVIth Rencontres de Moriond session QCD and High Energy Hadronic InteractionsHigh Energy Physics - Experimenttext
