A fundamental policy of collating "Genji monogatari taisei" was 'aiming at brevity,' so the differences which seem not to have affected the meanings such as the proper use of distinguishing between kanji (Chinese characters) and kana (the Japanese syllabary), hentaigana (anomalous Japanese cursive syllabary), itaiji (variant character), kana orthography, and so on, were mostly omitted.
『源氏物語大成』では、基本的な校合方針として「簡明を旨とする」という方針が示されており、漢字と仮名(文字)の使い分け、変体仮名、異体字、仮名遣いなど意味に影響を与えないと考えられた校異は多くの場合省略されている。
