Helen H. Metzelaar, the author of “Rosa de Vries: A Dutch Diva and Transatlantic Opera Culture” in the May 2014 issue of Journal of the Society for American Music, was omitted from the list of contributors. Her entry is as follows:

Helen H. Metzelaar is an affiliate researcher at the University of Amsterdam since her early retirement. She has published widely on gender issues and contributed to the New Grove Dictionary and Die Musik in Geschichte und Gegenwart. Her book on six Dutch women composers won an honorable mention from the prestigious Dordtse Academie. She is currently preparing a book on the de Vries opera dynasty and a new edition of a Dutch translation of Tosi's Osservazioni sopra il canto figurato (1723).

We regret the oversight.
