Child considered that folk ballads came from a more democratic time in the past when society was not so rigidly segregated into classes, and the "true voice" of the people could therefore be heard. He conceived "the people" as comprising all the classes of society, rich, middle, and poor, and not only those engaged in manual labor as Marxists sometimes use the word.

Though there were no graduate schools in America at the time, a loan from a benefactor, Jonathan I. Bowditch, to whom the book was dedicated, enabled Child to take a leave of absence from his teaching duties to pursue his studies in Germany. There Child studied English drama and Germanic philology at the University of Göttingen, which conferred on him an honorary doctorate, and at Humboldt University, Berlin, where he heard lectures by the linguists Grimm and was much influenced by them.

In 1956 four albums (consisting of eight LPs) of 72 Child Ballads sung by Ewan MacColl and A.L. Lloyd were released: The English and Scottish Popular Ballads, Vols. 1–4.
