Not Every Word in a Book Has the Same Standing

In a critical edition there is a difference between the author’s text, the editor’s footnote, and a commentator’s gloss. The corpus is built on that distinction structurally: every passage is tagged with its nature, and retrieval treats each layer according to its station.

The mother source

The critically edited digital editions published by the Ahlulbayt Library — the largest digitization project of the Imami heritage — in their original structural format, preserving the page numbering of the reference print editions, their editors’ footnotes and their book cards. Where no text edition exists, a scanned edition is used and every result from it is explicitly labelled as such.

Covered disciplines

Hadith

The canonical collections and compilations of Shia hadith across their strata.

Jurisprudence & its principles

Core texts, commentaries, glosses and lesson transcripts.

Exegesis & Quranic sciences

Narrative and inferential commentaries.

Theology

The foundational works of doctrine and disputation.

Biographical evaluation (Rijal)

Rijal works, catalogues and hadith terminology.

Ethics, history, supplications, lexicons

And the library’s other disciplines, each with its label.

Structural distinction within a single book

Every book’s card

Each book carries a complete bibliographic card parsed automatically from its source: title, author and death year, editor, edition and print year, publisher, volume, and library classification — available to the researcher through a dedicated tool, so citation precedes quotation.

When a text is absent, the corpus does not invent a substitute — it states the absence.
