A golden age for heavy quarkonium physics dawned at the turn of this century, initiated by the confluence of exciting advances in quantum chromodynamics （QCD） and an explosion of related experimental activity. The subsequent broad spectrum of breakthroughs, surprises, and continuing puzzles had not been anticipated. In that period, the BESII program concluded only to give birth to BESIII; the B-factories and CLEO-c flourished; quarkonium production and polarization measurements at HERA and the Tevatron matured; and heavyion collisions at RHIC opened a window on the deconfinement regime. Recently also ATLAS, CMS and LHCb started to contribute to the field. For an extensive presentation of the status of heavy quarkonium physics, the reader is referred to several reviews [1-8]. This note focuses on experimental developments in heavy quarkonium spectroscopy with very few theoretical comments. Some other comments on possible theoretical interpretations of the states not predicted by the quark model are presented in the mini-review on non qq-states.

Since 2002, the treatment of the branching ratios of the φ（2S） and Xc0,1,2 has undergone an important restructuring. When measuring a branching ratio experimentally, it is not always possible to normalize the number of events observed in the corresponding decay mode to the total number of particles produced. Therefore, the experimenters sometimes report the number of observed decays with respect to another decay mode of the same or another particle in the relevant decay chain. This is actually equivalent to measuring combinations of branching fractions of several decay modes.
