Field notes

The homepage breaks the archive into year and month indexes, with separate lists for anime works, manga works, and magazines. Its monthly summaries distinguish direct records from activity supported by a stated run period, estimates drawn from neighboring records, and unresolved cases. The site attributes its 1990–2019 corpus to Japan’s Media Arts Database and says individual pages show date precision and supporting evidence.
