Existing books are basically divided into two groups, namely those considered to be close to the original (a book owned by the Cabinet Library, a book owned by the Heian Museum of Ancient History, etc.) and those with some omissions and out of order pages which are believed to be the manuscript of Sanemori TOIN (a book owned by Sonkeikaku Bunko Library).
大きく分けて原本に近いと考えられる本（内閣文庫・平安博物館所蔵本など）と洞院実守書写と伝えられるものの、一部に脱落と錯簡が見られる系統（尊経閣文庫所蔵本など）のものが存在する。
