The International Workshop on Heavy Quarkonium 2014 took place at  CERN, on November 10-14 2014. It was the 10th edition of an endeavour started at CERN in November 2002. This meeting was an opportunity to celebrate a fifteen-year-long joint research enterprise that has seen a cornucopia of new data pouring out and new theory challenges met or identified. The LHC experiments already have had, and will continue to have, an important role in shaping this field.
