CatholicCorpus — Extracted Text

Pre-extracted plain text from the CatholicCorpus — 2,000 years of the Catholic intellectual tradition, ready for NLP, RAG, and digital humanities.

This dataset contains 47,407 plain text files (5.7 GB, 2.64 billion GPT-2 tokens) extracted from the raw source corpus (PDF, EPUB, TEI XML, HTML). If you need the original source formats, see the raw corpus.

Quick Start

from datasets import load_dataset
ds = load_dataset("CatholicCorpus/catholiccorpus-text")

Or clone directly:

git clone https://huggingface.co/datasets/CatholicCorpus/catholiccorpus-text

Known Gaps

This is the v1.1 text layer. Not every file in the raw corpus has a corresponding text extraction:

5 oversized PDFs (>200 MB each) were skipped: Butler's Lives complete edition, Haydock Douay-Rheims Bible, Breviarium Romanum (2 vols), and Missale Romanum 1962. These total ~1.85 GB of raw source not yet extracted.
115 files produced empty extractions (image-only scans with no embedded text layer, or non-prose XML schemas).
9,932 .pos.xml files were intentionally skipped (duplicates of the regular XML).

These gaps are documented in full in EXTRACTION_GAPS.md and targeted for the v1.2 OCR Enhancement milestone.

If you need the raw files for the gaps above, download them from the raw corpus.

Extraction Quality

Quality varies by source format:

TEI XML and HTML sources (Tasks 01, 02, 04, 08, 17) produce clean, high-quality text.
EPUB sources (Task 16 — Patrologia Graeca) produce good text with occasional formatting artifacts.
PDF sources (Tasks 05–07, 09, 11–15) vary widely. Modern PDFs with embedded text layers extract well. Older archive.org scans may contain OCR artifacts (garbled characters, missing diacritics, broken line breaks).

Licensing

The same three-tier licensing model as the raw corpus applies:

Tier 1: Public Domain — the vast majority (pre-1928 U.S. publications, authors deceased 70+ years)
Tier 2: Creative Commons — SBL Greek NT (CC BY 4.0), Rahlfs LXX (CC BY-NC-SA 4.0)
Tier 3: Copyrighted / Referenced Only — Task 17 (Modern Magisterium) content is under copyright
