The idea of the present work grew out of Mr Child's editorial labors on the series of the 'British Poets,' already referred to. For this he prepared a collection in eight small volumes (1857-58) called English and Scottish Ballads.[6] This was marked by the beginnings of that method of comparative study which is carried out to its ultimate issues in the volumes of the present collection. The book circulated widely, and was at once admitted to supersede all previous attempts in the same field. To Mr Child, however, it was but the starting-point for further researches. He soon formed the plan of a much more extensive collection on an altogether different model. This was to include every obtainable version of every extant English or Scottish ballad, with the fullest possible discussion of related songs or stories in the "popular" literature of all nations. To this enterprise he resolved, if need were, to devote the rest of his life. His first care was to secure trustworthy texts. In his earlier collection he had been forced to depend almost entirely on printed books. No progress, he was convinced, could be made till recourse could be had to manuscripts, and in particular to the Percy MS. Accordingly he directed his most earnest efforts to securing the publication of the entire contents of the famous folio. The Percy MS. was at Ecton Hall, in the possession of the Bishop's descendants, who would permit no one even to examine it. Two attempts were made by Dr Furnivall, at Mr Child's instance, to induce the owners to allow the manuscript to be printed,--one as early as 1860 or 1861, the other in 1864,--but without avail. A third attempt was more successful, and in 1867-68 the long-secluded folio was made the common property of scholars in an edition prepared by Professor Hales and Dr Furnivall.[7]
