The work's own structure
Reviewed edition: Leonine text identified on the Corpus Thomisticum part pages and curated by the Corpus Thomisticum project. Division axes: part → question → article. Structural nodes alone do not assert commentary citations.
Record-local commentary evidence
Commentary citations: work locus ↔ Dante locus
