# CatholicCorpus — Extracted Text

Pre-extracted plain text from the [CatholicCorpus](https://huggingface.co/datasets/CatholicCorpus/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](https://huggingface.co/datasets/CatholicCorpus/catholiccorpus).

## Quick Start

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

Or clone directly:

```bash
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](https://github.com/CatholicCorpus/catholiccorpus/blob/main/text_extraction/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](https://huggingface.co/datasets/CatholicCorpus/catholiccorpus).

## 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

See the [About page](https://catholiccorpus.org/about/) for full licensing details.
