of the Jikji is preserved by the Manuscrits Orientaux department of the National Library of France. On September 4, 2001, the Jikji was formally added to UNESCO's Memory of the World. The Jikji Memory of the World Prize was created in 2004 to commemorate the creation of the Jikji. Restoration The restoration process of the lower volume of Jikji was completed in 2013, restoring pages 2 to 14 by January of 2012 and pages 15 to 29 in January of 2013. In March of 2013, the Cheongju Early Printing Museum commissioned the Humanities Research Institute at Kyungpook National University to research further restoration processes to complete a full restoration of the two volumes of Jikji. The completed restoration of the Jikji metal movable type was revealed at its Metal Type Casting Training Center, having successfully replicated the 31,200 characters in the upper and lower volumes of Jikji with a total of 78 plates engraved with 400 characters per plate. This restoration work, done by expert Im In-ho, was done by reproducing the printed type of Jikji using the wax casting method that was used widely at the time of Jikji's original creation. The wax casting method engraves letters by attaching the letters to beeswax that were procured by heating honeycomb. A mold of the letter is then made by wrapping it with soil and pouring molten iron into the spaces where the wax has melted. Because only one incomplete copy of the metal type printed Jikji remains, missing information was filled in by referring to the woodblock print version of Jikji, published a year after the metal type printed version. The new restoration then now includes the page of the lower volume that was lost in the copy at the French National Library. The typeface replicates the type of Jabidoryangchambeophae, which is known to have been produced at Heungdeoksa Temple in Cheongju around the same time period. Characters not found in the Jabidoryangchambeophae were created by combining strokes as printed in the lower volumes of Jikji. In total, Cheongju city invested a total of ₩1.81 billion(~$1.5 million) on the Goryeo era metal type restoration project from 2011 to 2016. Controversy Towards the end of the Joseon Dynasty, French diplomat Victor Collin de Plancy bought the second volume of the Jikji in Seoul and took it to France, where it is now kept at the National Library of France in Paris.
