"This book may be regarded as a sequel to my 'Ballad criticism in Scandinavia and Great Britain during the Eighteenth Century,' published in 1916. The geographical field is much the same in this work as in that: Britain, America and the Scandinavian countries; in this instance, however, I have given relatively greater space to the English and Scottish ballads and their history than in the other." Grundtvig-Child index in book, as well as extensive bibliography.
