However, as folklorist and ethnomusicologist Mary Ellen Brown has pointed out, Child's denigration of the later Robin Hood ballads is evidence of an ideological view he shared with many other scholars of his time who wanted to exclude cheap printed ballads such as these from their pedigree of the oral tradition and early literature. Child and others were reluctant to include such broadsides in their collections because they thought they "regularized the text, rather than reflecting and/or participating in tradition, which fostered multiformity."
