“Chinese classic documents from the Ryukyu Kingdom era published” (4/1/14): The curator of the Uruma City Library Atsushi Enokawa, who took part in the project, said, “We took 20 years to research documents lost during the Battle of Okinawa, and we confirmed that various institutions had preserved a total of 600 documents. Many documents flowed out to the main islands of Japan during the pre-war period. It is important for researchers to read these documents at once.”

“Okinawan ‘treasures’ put on the Internet” (7/3/11): In order to make “treasures” of Okinawa more widely known to the public, the Okinawa Prefectural Library has digitalized 610 valuable works from the past such as ancient maps, documents and pictorial diagrams, all of which the library owns, and has started to put them on the Internet. Those works are collected together in a section called the “Digital library for valuable works.” …For the official website for “Digital library for valuable works,” access http://archive.library.pref.okinawa.jp/
