What is "jikji"

Jikji is the abbreviated title of a Korean Buddhist document, whose title can be translated "Anthology of Great Buddhist Priests' Zen Teachings". Printed during the Goryeo Dynasty in 1377, it is the world's oldest extant book printed with movable metal type. UNESCO confirmed Jikji as the world's oldest metalloid type in September 2001 and includes it in the Memory of the World Programme.

Jikji was published in Heungdeok Temple in 1377, 78 years prior to Johannes Gutenberg's acclaimed "42-Line Bible" printed during the years 1452–1455. The greater part of the Jikji is now lost, and today only the last volume survives, and is kept at the Manuscrits Orientaux division of the National Library of France.
