A Mastodon user responses to Sumida's analysis, noting that while the National Diet Library is supposed to collect all publications since its founding through a mandatory deposit system, gaps are frequently discovered. Pre-founding materials are scattered collections from predecessor institutions, and the library's coverage of all historical publications is uncertain. The respondent suggests the National Diet Library could actively search for and acquire dispersed materials.
