In the early decades of the 18th century, Amsterdam was one of the most important publishing cities in the world. Vivaldi, Corelli, Albinoni and Locatelli all chose to publish in Amsterdam rather than in Venice because of the superior quality of Amsterdam publications. But pirate copies soon came on the market, for which the composer did not receive a penny. In 1719 – from the presses of the reputable publisher Roger no less – an unauthorised version of a number of Handel’s pieces for harpsichord appeared.
