I just googled “Korean folk tales” and one of my class projects showed up!
In a history of children’s literature course, I wrote an essay comparing Tales of a Korean Grandmother (1947) with Berta Metzger’s Tales Told in Korea (1932), and I created the above website for a folklore class, both in my first semester as a doctoral student. I’ve since learned of earlier folk tale collections; for example, Horace Allen’s Korean Tales (1904) and William Elliot Griffis’ Korean Fairy Tales (1911).
I smell another research project!!
