Data Sources and Updates

Source priority

Journal identity and policies come first from the journal's or publisher's own website; indexing status is checked against the official databases; data from third-party platforms keeps the platform's name and when it was fetched.

Current journal sources

LetPub data is collected with authorisation; the original HTML is kept in a private data layer, and public pages show only permitted structured fields and aggregate statistics.

Updates and corrections

Every page shows when its data was last observed. To report an error, send the journal, the field, the value you suggest and a source we can check.
