Public domain
The work is not in copyright in the relevant jurisdiction (for example a pre-1929 US publication, or a dedicated dedication). We still need evidence — a catalog record, a national library entry, or the dedication itself.
Contribute
We only seal work that is free to publish. There is no pirate ingestion path, no in-copyright commercial scan, and no way for a submission to overwrite a sealed edition. This form writes a JSON record for curators. It does not mint, and it does not change the catalog.
Creative Commons
A CC license that permits free public reading of the full text. Commercial-all-rights-reserved scans are not eligible. Link the license deed and the author’s notice.
Author grant
The living author grants this library the right to seal and host a specific edition. The grant is recorded; the seal still cannot be rewritten later.
Estate grant
The rights holder after the author’s death grants a specific edition. Same immutability rules as an author grant.
