Build the map of comics with us
Quadrin tracks every work, every chapter, where each chapter was first printed and every place it was reprinted. Readers keep that map accurate — and every approved contribution earns points.
How the data fits together
Everything hangs off the chapter
A work is split into chapters. Each time a chapter is printed — in a magazine issue or in a collected edition — a story link connects the two. Follow one real path:
Work
Naruto
The creative work as a whole
Volume
Naruto · Volume 1
The work's own numbering
Chapter
Naruto · Chapter 1
The unit that gets printed
Story link
Connects one chapter to one printing, with its order, page count and flags
In a magazine
OriginalNaruto → Original magazine: Weekly Shōnen Jump
Nobody typed this on the work page. It appears because chapter 1 has an Original story link to a Weekly Shōnen Jump issue.

- Volume
- The work's own grouping of chapters, as numbered by the work. Not a product you buy.

Where the data comes from
Grand Comics Database
The catalog was first seeded from the GCD dump: comic series, issues, stories and credits.
MyAnimeList and AniList
Manga and other works were matched against MyAnimeList and AniList to fill in titles, dates and covers.
The community
Since then, every new entry, correction, story link and cover comes from reader submissions.
FAQ
Common questions
What counts as Original?
The first time a chapter was ever printed, anywhere. Usually that is a magazine issue; for graphic novels it can be a collected edition. Translations, compilations and later releases are reprints, even if they are the first release in your language.
Why doesn't a work show an Original Magazine?
Because none of its chapters has an Original story link to a magazine edition yet. Open the issue where the chapter first appeared, add the chapter to its story list and mark it Original.
Should I add a volume or a collected edition?
Add a volume to describe how the work itself is numbered. Add a collected edition for a specific product with an ISBN, a language and a publisher. Most works need both.
What is a run?
A work that has no chapters of its own: an ordered selection of another work's chapters, like a famous creative team's stint on a long series.
What do Colored and Altered mean?
Colored: this printing was colorized compared with the original. Altered: it was edited or censored compared with the original. Both describe the printing, not the chapter.
A chapter was reprinted many times. Do I link every one?
Yes — each printing is its own story link, and each one earns points. Adding page counts earns a small bonus.
Who reviews submissions?
Other users vote, or a moderator validates directly. The points are the same either way.
Do points expire?
No. Points accumulate permanently. Only the daily, weekly and monthly leaderboards reset.
