As I search, I continually encounter a few resources that remain unavailable to me through the Internet and the American library system. I’ve decided to post them here, and should I find them and be able to read them, I’ll tick them off.
“Master Thumb,” retold by Htin Aung – What is the character’s name in the original dialect?? May 15, 2016: Miiiight have possibly found it, maybe.
Tale of the “hedgehog-sized boy.” The folklore collection of Jakob Hurt III, 27, 339/44. Estonian Literary Museum.
“Thumb Boy” – name in original Oroqen dialect.
“Draganka,” from Senovo. Recorded by Milena Benovska in 1990. The only lead I’ve found on this is the title of a thesis by Benovska - "Териоморфни митически персонажи в българския фолклор/ Theriomorphic mythical characters in Bulgarian folklore."
A couple of equivalents:
"Story-type Analysis of Mongolian Folktale Sheep-Tale Boy"
Nights of Baghdad – Iraqi Folktales
“A Dwarf.” Zong In-sob, Ondol Yawa, Nihonshoin, pp. 380, 1927. May 15, 2016: Found equivalent.
Irish Thumblings. I recently checked out The Types of the Irish Folktale, which listed a lot of references for the Thumbling tale type, but to my disappointment, they've been pretty hard to track down.
This website is based on my research into folklore.
