The 1000 Novels Corpus is released under Creative Commons Attribution 4.0 International by CLARIN-PL / Wrocław University of Technology, with attribution to the corpus authors and maintainers.

Rights note (per-text screen, September 2026)

The CC-BY-4.0 licence covers the corpus as compiled by CLARIN-PL. It cannot license third-party rights in the individual novels and translations. A per-text screen of the released file found:

status	texts
public domain in Poland by term (author and any translator died by 1955)	830
marked public domain by Wolne Lektury	10
in copyright; published by Wolne Lektury under CC BY-SA 3.0	17
author or translator could not be verified	143

Releases up to v0.2.5 label all 1,000 texts CC-BY-4.0. Before the next release, the 17 in-copyright texts should be relabelled CC-BY-SA-3.0 with Wolne Lektury attribution or removed, and the 143 unverified texts withheld until their rights are established.

Provenance

Pulled from SpeakLeash's public redistribution (speakleash-ds-pub, key 1000_novels_corpus_CLARIN-PL) of the upstream CLARIN-PL source. SpeakLeash credited as intermediate aggregator; upstream license/attribution preserved.

Filters applied (build_dynaword.py)

Minimal, per Dynaword guidelines (heavy filtering left to downstream use):

drop documents < 200 chars: 0
drop non-Polish (diacritic ratio): 0
exact cross-source dedup (sha1): 0
OCR alpha-ratio < 0.70 (OCR sources only): 0
read 1,000 → kept 1,000

Token counts are a fast tiktoken (cl100k) proxy (~1% off Llama-3); the canonical Llama-3 count is computed at release.
