From 1899-1900 he edited the journal Folklore, and he collected folklore and fairy tales which he compiled into five different collections: English Fairy Tales, More English Fairy Tales, Celtic Fairy Tales, More Celtic Fairy Tales, and European Folk and Fairy Tales. He was inspired by the Grimm's Brothers, and recognized that folk lore was an important part of a nation's identity. He wished that English and Irish children to have access to their own heritage, rather than reading French and German stories.
