Didn't do a lot of research yet, but here are a couple likely inclusions to the Memory of the World connection. 47 additions for 2015!

Republic of Korea - Confucian Printing Woodblocks (Historic Villages of Korea)

Japan - Archives of Tōji temple contained in one-hundred boxes (Historic Kyoto)

Israel - Aleppo Codex (Ancient City of Aleppo)

Germany - Documents representing the beginning and the early development of the Reformation initiated by Martin Luther (Luther Memorials in Eisleben and Wittenberg)

One more:

The Mappa mundi of Albi (has been kept at cathedral of Albi)

And ... The Golden Letter of the Burmese King Alaungphaya to King George II of Great Britain (I just saw a transcript of that one in the national museum of Myanmar in Yangon!)

Can you point out the direct relation between this & Hahoe or Yangdong, so I can add them to the connection? Could not find it on a first search

The Confucian Academies in Korea, particularly in North Gyeongsang province played a huge role in the publication, storage, and gathering of Confucian Woodblock Prints.

Inscribed within the Historic Villages of Korea WHS
- Byeongsanseowon Confucian Academy
- Oksanseowon Confucian Academy
- Donggangseowon Confucian Academy

The current collection is now housed in Andong, it used to be largely stored in the Confucian Academies themselves.

Potentially several connections based on the 78 newly inscribed documentary heritage.
