Kokusho Sōmokuroku

The revised and expanded edition was released by Iwanami in 1989; however, the only major changes are symbols which cross-reference the main index with the appendixes and companion volumes.

As of 2004, an online edition of the Kokusho Sōmokuroku is available at the website of the National Institute of Japanese Literature (NIJL).

The database is searchable by title, author, genre and date, but is only accessible in Japanese and does not list textual variants or library holdings.

It is a print version of the catalog of post-Meiji Japanese works listed by the NIJL, and contains a total of 91,000 entries, 43,000 of which do not appear in the original Kokusho Sōmokuroku.

The organizational structure is the same as the original volume, with the exception that alternate titles are listed in a separate index opposed to cross-referenced in the main text.
