『土佐日記』の研究(その校本と助詞・助動詞索引)  [in Japanese] A Critical Revision for the Text of ≫ Tosa-Nikki ≪ (Tsurayuki's Diary) with Its Indices Verborum  [in Japanese]

The book under the title "Tosa-nikki" by Kino Tsurayuki is a sort of travel diary from Tosa to Kyo after the completion of his term of office (Tosanokami). Of four kinds of the chief manuscripts, the one regarded as best is the original text in this treatise. Addition to this, by reference to three others, an original draft was edited. Thus, indexes of its odes, of parts parsed into phrases, and of particles & auxiliary verbs are compiled on the basis of the draft.
