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:

  1. Work

    Naruto

    The creative work as a whole

  2. Volume

    Naruto · Volume 1

    The work's own numbering

  3. 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

Original

Magazine edition

Weekly Shōnen Jump No. 42, 1999

One dated issue

Magazine

Weekly Shōnen Jump

The periodical title

In a collected edition

Reprint

Collected edition

Naruto, Vol. 01: The Tests of the Ninja

A product with ISBN, language and publisher

Series

Naruto (English line)

The publisher's line of collected editions

✦ Derived

Naruto → 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.

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.
