## The arenas' articles

Each article was read at the revision named (167 arenas), by its address `https://<en or ja>.wikipedia.org/w/index.php?title=<title>&oldid=<revision>` (the function `arenaSourceUrl` writes it). The authors of an article are listed in its history. The figures are in `scripts/arenas.data.json`, which holds each entry's article and revision; docs/references.md explains how they were read and docs/arenas.md lists every arena. The Japanese article is named by its title, as Wikidata links it; the name in Japanese is the package's (see docs/arenas.md, "Names").

The Japanese Wikipedia articles read for the names, with their revisions, are listed in [NOTICE.ja.md](./NOTICE.ja.md#アリーナ) by the same Wikidata item.
