What this review measures, and what it doesn't
Dated releases: manga, manhwa, manhua and webtoon published in France.
Series: A series groups the volumes of one title, with volume numbers and edition mentions removed.
New series: A series whose first dated release falls within the period. Reissues, box sets and collector's editions excluded.
Publishers: Co-editions are split on the "/" separator. A publisher is active if it has at least one release.
Groups: A group is the sum of its imprints. The imprint → group mapping is curated by hand; an unmapped imprint stays counted under its own name.
The limit that matters: The dataset measures published output, never sales — no French publisher discloses them. This review therefore describes
supply — what publishers choose to publish — a leading indicator, but not revenue.
Two known flaws this quarter
Typing is incomplete. 50.4% of the quarter's
releases (452) have no type in the dataset. This is not a measurement error,
it's a lag: Manga-News records are filled in after release, and September has only just
arrived. Any share-by-type published here is computed on the typed subset, never on the
total, and it will shift at the next recompute.
A duplicate, found and fixed. While preparing this review, June and July
2026 turned out to be counted twice: an old multi-month file (a raw export named
planning.csv) overlapped the clean monthly schedules for those two months.
The anomaly was massive — July showed 572 releases instead of 286, and the third quarter
1,182, a false "+41%" and a false record. The duplicates were confirmed by cross-checking
EANs (283 shared codes out of 286 for July, 290 out of 295 for June), then the 579 excess
rows were removed. The corrected quarter weighs
896 releases (7.0%). The public
dashboard was republished on this de-duplicated data the same day.
Finally, the editorial picks above are flagged as not measured: they reflect a
reader's expectations discussed on air before the titles' release, not a retrospective
reading or a dataset indicator.
