This book updates the 100-year old Schirmer edition of 17th and 18th century Italian Songs and Arias, used for 4 generations by most serious students of singing in all English-speaking countries. Paton's edition is into in the Schirmer edition, adds optional (and appropriate) vocal ornaments, and simplifies the accompanying harmonies. Paton's edition is also more useful to singers, as it contains three different translations of each song (word-for-word, singable, and the underlying emotional idea), and it transcribes all text into the international phonetic alphabet. The page layout is attractive. I use my copy every day.
