There is a two-line Okugaki (postscript) 'Written October (old calendar) 2, in the fourth year of Eikyu (in 1116), these old eyes helped me put a period, old Mototoshi,' written by the same hand as the text on the fragment equivalent to the end of the last volume, and there is also written 'composition was completed on the same date' by a different hand.
下巻末にあたる部分の断簡に、本文と同筆で「永久四年（1116年）孟冬二日、扶老眼点了、愚叟基俊」と二行の奥書きがあり、さらに別筆で「おなじとし月によみはてつ」と記されている。
