The sources are TEI P5 XML, normalised to Unicode NFC. Divisions, blocks, editorial metadata and CTS identifiers are kept as they are.
References
A canonical reference (book, chapter, line) is given only where the source attests it. Otherwise the passage keeps a local reference; nothing is guessed.
Presentation
The reader lays out prose, verse, drama, scripture, lexica, commentaries, mathematical texts, fragments and papyri each in their own way. Structural labels are kept apart from the author’s headings.
What is not done
No biography, translation or summary is added. Every page links its metadata, its CTS URN, its digital source when known, and its corpus release.
