Im Library of Congress Blog gibt es unter dem Titel «China’s Colossal Encyclopedia» einen Beitrag zur Yongle Enzyklopädie (1408):
«Over ensuing decades, however, the original edition was completely lost. Even now, how and when it went missing remains a mystery. Fortunately, parts of the duplicate set have survived — but just barely. Today, only 420 volumes, or 4 percent of the complete set, remain. This includes two newly discovered volumes that sold for more than $9 million at an auction in Paris in July 2020.
Of these, the Library of Congress holds 41 unique, inconsecutive volumes in its Asian Division. Acquired during the early 20th century via purchase and donation, they form the largest assemblage of Yongle specimens outside Asia.
Thanks to collaboration among custodial, cataloging, conservation and digitization teams, the Library’s Yongle collection is now fully cataloged and undergoing careful preservation work. Upon completion of a digitization project in progress, all 41 volumes of this 450-year-old encyclopedia will be made available online for readers around the world to study and appreciate up close.»
