The first part of the book is a compilation of reviews and articles extracted from The Gramophone online archive, referring to the recordings of Webster Booth and/or Anne Ziegler. The second part contains my own compilation of a discography of solo and duet recordings of Anne Ziegler and Webster Booth, including recordings made with other singers, the HMV Light Opera Company and recordings marked only with “with vocal refrain”. Most of the recordings in the discography are solo recordings by Webster Booth. I have marked duet recordings with Anne Ziegler, Anne Ziegler’s solos, and recordings which do not acknowledge Webster Booth (such as the HMV Light Opera Company and those marked “with vocal refrain”) with the following markers: *Duets. #Anne Ziegler solos. +With vocal refrain.
