New measurements of the di-electron partial widths for the 3 bound-state Upsilons and the J/psi are discussed. A determination of the total hadronic cross section for the psi(3770) is made, which solves a 20-year-old puzzle. The Y(4260) state is confirmed and its decay into 2 new modes is measured.7 pages, 2 figues, uses moriond.sty.
