When he was preparing to publish old typographic books, it is assumed that he ordered copies of the missing eight volumes (which were almost all blank) including the ones presented by Nagamasa KURODA in the same format as the manuscript which he had already had until then, making 51 volumes and using it as an original text to publish in 1605.
それにより古活字本開版の準備をしていた処に、黒田長政献上のものを含むめて、不足分8冊（白紙に近い紙）をそれまで入手していたものと同じ書式で書き写させて51冊とし、これを1605年（慶長10年）印行の底本としたのではと現在では推定されている。
