A shared bibliography

Sources are stored once and cited across species accounts and essays. Records support authors, title, year, journal, volume, issue, pages, DOI and stable database URLs.

Verification remains editorial work

The build checks record structure and broken source IDs. It cannot establish that an interpretation is correct or a source supports a claim. Those judgments require documented review.
