# CatholicCorpus — Backlog

Deferred work, ordered by when it should be picked up. Add new items at the top of the relevant section.

## Gaps to revisit

### Task 16 — Patrologia Graeca volumes 16 and 86
- **What:** Vols 16 and 86 of the Migne Patrologia Graeca are not on archive.org under any search pattern tried on 2026-04-15. The current script skips them via the `MISSING_VOLUMES = {16, 86}` set.
- **Coverage achieved without them:** 159 of 161 volumes (98.8%) via three chained sources:
  - Primary: `patrologia-volumes` (155 vols)
  - Fallback: `patrologia-graeca_202105` (fills 75, 106)
  - Single-vol items: `patrologiae_cursus_completus_gr_vol_087_2` (87) and `patrologiae_cursus_completus_gr_vol_007_irenaeus_tomus_unicus` (7)
- **Content at stake:** Both are early Patristics (1st–3rd c.). Vol 16 may contain material from Eusebius / Hippolytus; vol 86 from Sophronius / Maximus Confessor.
- **Where to look next:**
  1. Google Books / HathiTrust (they may have scans archive.org doesn't).
  2. documentacatholicaomnia.eu — a sister corpus that mirrors some Migne material.
  3. Specific French university digital libraries (Sorbonne, BnF Gallica).
  4. Direct probing of unpadded and differently-split archive.org patterns we might have missed (e.g. `patrologiae_cursus_completus_gr_vol_016_pars_*`).
- **Action:** Low priority — do once the main run completes and the rest of the corpus is stable.

## Long-running downloads (save for the end)

### Task 02 — Patrologia Latina full download
- **What:** Run the full PL download from Corpus Corporum (corpus idno 38).
- **Command:**
  ```bash
  cd 02_corpus_corporum
  python3 download_script.py --collection 38 --resume
  ```
- **Scope:** 5,277 texts, ~85.5M words. Produces TEI XML + POS-tagged XML where available.
- **Expected runtime:** ~10–11 hours at default rate limiting (1.5s between nav requests, 2s between downloads). Discovery phase alone is ~2.8h because PL has 1,528 authors and 5,204 works.
- **Disk:** ~2–5 GB estimated.
- **How to speed up (if needed):** `--delay 0.8` roughly halves total time to ~6h. Default is the polite setting for a university research server — only reduce if there's a real deadline.
- **Resume:** State saved every 10 texts to `.download_state.json`. Safe to Ctrl-C and restart with `--resume`.
- **Run it in:** `nohup`, `screen`, or `tmux` so laptop sleep doesn't kill it.
- **Validation before kicking off:** run `--collection 17098` (Libri sacri, 7 texts, ~1 min) first to confirm the download endpoint is healthy end-to-end.
- **Status:** Script fixed and verified via dry-run on 2026-04-15. Ready to execute. Deferred — do last.

### Task 02 — Other large Corpus Corporum corpora (optional)
Candidates if PL goes well and you want more Latin coverage. Sorted by size:
- Acta Sanctorum (idno 21967) — ~52.7M words
- Graeca miscellanea (idno 21155) — ~10.8M words (Greek, not Latin — skip unless wanted)
- Thomas Aquinas (idno 11975) — ~8.1M words, but `accessible_texts_count=0` on the root listing, so downloads likely blocked. Verify before scheduling.
- Neolatinitas (idno 14001) — ~7.7M words
- Auctores scientiarum varii (idno 12130) — ~7.3M words
- MGH (idno 14010) — ~6.6M words
- Scriptores Ecclesiastici (idno 14007) — ~5.8M words

Decide scope before starting — each is a multi-hour run.
