Epistemic status

Unattested inferred source corpus.

This article describes an entity that is not directly attested. It is an inference from the evidence listed below.

Summary

The Yongle Encyclopedia implies a vanished source corpus: thousands of books and textual witnesses that once fed the compilation and in some cases are now recoverable only through its surviving excerpts.

What is being inferred

The inferred object is not the Yongle Encyclopedia itself, which is directly documented. It is the underlying source corpus: the lost or partially lost works, versions, and textual witnesses excerpted into the encyclopedia.

What is attested

  • Library and reference sources describe the Yongle Encyclopedia as a massive compilation from thousands of texts.
  • Only a small portion of the encyclopedia survives.
  • Institutional descriptions state that some lost texts are now studyable only through the encyclopedia.

Why infer this entity

  • A compilation of this scale requires a prior source corpus, including texts that later disappeared independently.
  • Surviving volumes preserve traces of works that no longer survive whole elsewhere.
  • The inference is plural: a corpus layer, not one lost book.

Evidence ledger

The imported evidence ledger uses Library of Congress digitization and catalog records plus Britannica reference material. These sources support the scale, loss pattern, and source-corpus role of the Yongle Encyclopedia.

Counterarguments

  • The source layer is heterogeneous and cannot be treated as a single coherent archive.
  • Some source works may survive elsewhere, so each item requires separate verification.
  • The surviving encyclopedia volumes are only a small sample of the larger compilation.

Confidence scores

What would change the score

  • A systematic index of which source texts survive only in Yongle excerpts would raise specificity.
  • Discovery of further Yongle volumes would expand the recoverable layer.
  • Evidence that a cited source survived independently would move that item out of the inferred-loss category.

Related lacunae

  • Lost Chinese textual witnesses.
  • Ming encyclopedic compilation practices.
  • Source preservation by excerpt.
