A Hyperlinked Edition of the Huainanzi

More than a third of the Huainanzi is woven from pre-Han writings. This edition makes that weave visible — chapter by chapter, parallel by parallel.

one third of it shared with earlier writings

  • Laozi
  • Zhuangzi
  • Lüshi chunqiu
  • Guanzi
  • original to Liu An’s court

A passage, colour-coded

The Way covers heaven and supports earth, spreads across the four quarters, opens out to the eight limits; too high to reach, too deep to fathom — it wraps heaven and earth and gives form to the formless.

  • Laozi
  • Zhuangzi
  • Lüshi chunqiu
  • Guanzi

Each coloured run comes from a different pre-Han writing; in the hyperlinked edition, clicking a passage opens every candidate source.

How it was made

  1. Trace parallels: ctext.org · Text Alignments
  2. Cross-check against the curated list
  3. Remove false positives by hand
  4. OCR and mark up two critical editions

Textual parallels were traced with two open tools, ctext.org and Text Alignments, then read against a manually curated list and checked for false positives. Two critical Chinese editions were OCR’d, marked up and aligned.

The aim

To give scholars worldwide a tool for exploring the Huainanzi’s intertextuality, and to substantiate the argument that Liu An and his courtiers used intertextuality deliberately — writing as weaving.

What the edition does

A researcher can search the whole work and its parallels, zoom from a bird’s-eye view of the chapters down to a single line, annotate the text and export or import those annotations, and open a pop-up of every candidate parallel behind a colour-coded passage.

What was difficult

Tracing and double-checking every parallel is slow — the first two chapters took months.

Future workflows will be scaffolded so the computing side never idles.

It is not always clear which pre-Han text a passage refers to.

Every candidate parallel is offered in a pop-up, rather than one answer being imposed.

On the road

The project was presented at its early stage in the “A Taste of Digital Scholarship” talk series, part of the Library’s Digital Scholarship Roadshow, on 17 March 2026.

What comes next

Undergraduate research courses continue, a GRF application is planned for autumn 2026, and the aim is a hyperlinked edition of the complete Huainanzi by the end of 2029 — with a reusable blueprint for hyperlinked editions of early Chinese writing in general.
