Library
One work can have many editions.
Originals and translations, paperbacks and ebooks, collections and online serials are recorded separately and linked to the same work. You know which edition you have, and your series progress stays clear.

Four types of release
Every release is identified by type.
A book sold in three stores still has one edition record, with three places to buy it. Unauthorized reproductions are recorded separately from the authorized edition.
Published editions
Publisher volumes, paperbacks, ebooks, or special editions. The record reflects what was actually published and is not changed later.
Online publication
An online serial is a real release. Keep its original URL and dated snapshots.
REZICS snapshot
Archive the content selected at a moment on REZICS as an edition that later revisions do not change.
Virtual edition
A user translation follows the structure of a published edition and states its coverage, such as chapters 1 to 20 of a 100 chapter book. It does not represent an actual publication.
Translations
Every translation names its translator and source.
Official translation
A publisher’s translation is a separate edition, with its translator and rights listed.
Fan translation
It belongs to its translator and is linked to a specific source edition. It is never labeled official.
Machine translation
It is a new text like any other translation, identified as machine generated.
AI assisted
A human translation made with AI assistance is identified as such, so readers can filter by it.
Every translation passage has a status
- Not translated
- Translated
- Reviewed
- Final
- When the original changes, the matching translation is marked as needing an update. It is not deleted or silently moved to new text.
- User translations are private at first. To make one public, there must be a basis: the source is in the public domain or under an open license that allows translation, the author agrees, or the author has provided a translation license.
- Authors can also decline to link a source work to a translation.
- Traditional Chinese is not silently changed to Simplified Chinese. Converted text is identified as converted, and proper names are left unchanged.
One work or two
Which changes still belong to the same work.
The test is whether the story remains compatible or is intentionally retold. Word count, language, ISBN, and marketing copy do not decide it.
Correct typos, make minor edits, or add compatible chapters
One work, with separate editions and releases.
Change the order, keep the events
One work, with both orders preserved.
Change the cause and effect, or make the endings incompatible
Two works, linked as a rewrite.
Rename the protagonist
If it is only an alias, it is still the same work.
Retell the story from the beginning
Two works, linked as a reboot.
Remove the online version, or continue only online
This changes coverage and availability, not the number of works.
Reading the online version does not mark a rewritten edition as finished. A person must confirm chapter correspondences between the two.
Order
Publication order and reading order can differ.
Example: two orders for the same series. Each volume keeps its identity.
Publication order
- Volume 1
- Side story
- Volume 2
- Volume 3
Recommended reading order
- Volume 1
- Volume 2
- Side story
- Volume 3
Collections
A collection is one edition that contains several volumes. Each volume remains its own work, with its own ratings and progress.
Subseries
Subseries can each start at volume 1, with an overall order connecting them.
Finish a series
Series progress counts required volumes only. Optional side stories and specials do not affect completion.
Series progress
Caught up with current releases, finished all published volumes, series complete, and chapter links unconfirmed are shown separately.
Enter an ISBN, Find that edition.
An ISBN identifies one edition, not the work itself. Start from an ISBN or ebook entry to find its edition, the text or translation it contains, and the work above it. For example, A Certain Magical Index has Japanese, Traditional Chinese, and English editions, each with its own ISBN, all pointing to the same work.
