## Files

- `metadata/NN_<virus>.json` — full metadata incl. abstracts, per virus
- `metadata/NN_<virus>.csv` — same, spreadsheet-friendly (no abstract)
- `master_index.csv` — one row per unique paper, with `viruses` column showing all that mention it
- `pdf/_pmc_pool/*.pdf` — deduplicated open-access PDFs (the actual papers)
- `pdf/NN_<virus>/*.pdf` — hardlinks organising PDFs by virus
- `fulltext/_pmc_pool/*.xml` — deduplicated open-access full-text XML (JATS, machine-readable)
- `fulltext/NN_<virus>/*.xml` — hardlinks organising full texts by virus

## Caveat

PDFs/XML are only available for the open-access subset (records with a PMCID). PDFs come from Europe PMC's render service with an Unpaywall publisher-PDF fallback. Paywalled articles are fully catalogued in the metadata/master index with their DOI for manual retrieval, but their PDFs cannot be downloaded.
