People have been coming from Okinawa every year since 1989 to study the Li Dai Bao'an at the NTU library. Other copies of the Li Dai Bao'an can be found in libraries throughout Japan, but there are discrepancies between the different versions, so scholars must compare them to correct deficiencies.
以現存於台大圖書館的《歷代寶案》來說，自一九八九年開始，沖繩人每年來台作研究，與現存日本各地的不同版本的《歷代寶案》作比對，並加以補充校對。
