Which UNESCO register includes Grimm's Fairy Tales as documentary heritage?

The UNESCO register that includes Grimm's Fairy Tales as documentary heritage is the Memory of the World Register.

UNESCO inscribed the Grimms' collection under its German title, Kinder- und Hausmärchen (“Children's and Household Tales”), in 2005. The listed material is associated with the Brothers Grimm Museum in Kassel, Germany.

The recognition belongs to UNESCO's documentary-heritage program, not its World Heritage List for monuments and places. It also differs from the Intangible Cultural Heritage List, which recognizes living traditions, practices, and knowledge rather than historical documentary collections.

The Grimm collection is important because Jacob and Wilhelm helped preserve German-language folktales in printed form, while their editions also influenced children's literature worldwide. The Memory of the World designation highlights the historical value of the books and related documentary materials.
