Data sources and methodology
Catalog metadata
Titles, creators, publication dates, volume counts, and Japanese summaries are maintained in the local Yomitai catalog. English summaries are original translations of those short Japanese summaries.
Cover art
Cover metadata may come from publisher records, Google Books, or MangaDex. Yomitai only applies automated matches when the original Japanese title is exact and supporting metadata is unambiguous. Otherwise a clearly branded generated cover is shown instead of guessing.
Circulation
Reported circulation uses the dated source linked on each series page. Estimates are labeled separately and should not be treated as publisher announcements.
Reading time
Reading times are estimates derived from page or volume counts and a configurable reading pace. They are intended for comparison, not as official figures.
English titles
When a market-specific English title can be verified, the source is linked on the series page. Otherwise Yomitai displays a romanized or editorial title and labels it as pending verification.
