+# Usenet Corpus 1980–2013 — Full (Samples)
+
+A small, browsable **showcase sample** of the *Usenet Corpus 1980–2013* (cleaned)
+dataset — long-form, pre-web Usenet posts. This repo is a free preview; the full,
+commercially-licensed corpus (408.0M posts, 103B tokens) is at:
+
+- **Full cleaned dataset (gated):** https://huggingface.co/datasets/OwnedByDanes/Usenet-Corpus-1980-2013-Full
+- **Threaded companion:** https://huggingface.co/datasets/OwnedByDanes/Usenet-Corpus-1980-2013-Threaded
+
+## What's in this sample
+
+Eleven gzipped JSON Lines files: one per hierarchy (about 5,000 posts each; ALT about 2,000),
+plus a **Big 8 combined** and an **all-hierarchies combined** sample (about 9,000 posts
+each). The per-hierarchy and combined files are independent draws and overlap.
+
+Posts are selected as **whole conversations (threads) of at least 3 posts** — a
+deliberate showcase cut so the sample contains coherent discussions rather than
+isolated one-off posts. It is **not** representative of the full corpus's shape,
+which is mostly single-post threads; it is curated for readability. Related posts
+sit together within each file, and cross-post duplicates are removed within the
+sample. These are the same posts as the *Threaded* sample repo, without the three
+thread fields — see that repo if you want the conversation structure.
+
+## Record schema
+
+Each line is a JSON object:
+
+| Field | Type | Description |
+| --- | --- | --- |
+| `id` | string | Stable per-post identifier (`msg-` + hash of the original Message-ID). |
+| `group` | string | Newsgroup the post was archived under. |
+| `date` | string | Original post date (RFC 2822). |
+| `author` | string | Author display name as posted. Email addresses are redacted. |
+| `subject` | string | Subject line. |
+| `text` | string | Post body. |
+
+## Provenance and safety
+
+Drawn from the cleaned, de-duplicated corpus: binary attachments and
+`alt.binaries.*` removed, adult groups excluded, author emails redacted,
+Message-IDs replaced with hashes, and content matching ClamAV malware signatures
+removed (the corpus passes a whole-file ClamAV scan with no detections). Content is
+otherwise preserved as posted — unmoderated historical text that may be offensive,
+biased, or wrong, and should be treated as a primary historical source.
