In addition, the following three kinds of volume of the Oshima-bon manuscript were not used for the original text, and the Ikeda-bon manuscripts (owned by the old Ikeda family) which was said 'the second best after the Oshima-bon' and transcribed by Tameuji NIJO were used instead: the missing volume in the Oshima-bon (Ukifune [A Drifting Boat]), the volumes in Oshima-bon that was not written by Masayasu ASUKAI, but supplementarily written by the posterity (Kiritsubo [The Paulownia Court], Yume no Ukihashi [The Floating Bridge of Dreams]), and the volumes in the Oshima-bon which were written by Masayasu ASUKAI, but based on the Beppon line manuscripts (Hatsune [The First Warbler]).
また、大島本に欠けている巻（浮舟(源氏物語)）、大島本があってもそれが飛鳥井雅康の筆でなく後人の補筆である巻（桐壺、夢浮橋）、大島本が飛鳥井雅康の筆であっても別本系統の本文であることが判明した巻（初音(源氏物語)）、については大島本を底本にせず「大島本ニ次グベキ地位ヲ有スル」とされた二条為氏の書写と伝えられる池田本（旧池田家所蔵本）を底本にしている。
