# Attribution — Lane's Lexicon

The **Meaning** section on each root page is from **Edward William Lane's *An Arabic-English Lexicon*** (London: Williams and Norgate, 1863–1893), the standard classical Arabic–English lexicon. Lane (d. 1876) is long in the public domain.

The digitisation is the **Perseus Digital Library** (Tufts University) TEI text, taken from the `laneslexicon/lexicon_xml` mirror of Perseus's `originals`, pinned to commit `51e0794420da4f2b20148dc0395d4bfdbe60ee2a`.

- **File-level terms (embedded in each TEI file):** “This text may be freely distributed, subject to the following restrictions: (1) You credit Perseus, as follows, whenever you use the document: “Text provided by Perseus Digital Library, with funding from The U.S. Department of Education and The Max Planck Society.” (2) You leave this availability statement intact.

Both are attribution + share-alike, so this text is displayable **and** redistributable (unlike a NoDerivatives edition). When you redistribute it, keep this attribution and the Perseus availability statement, credit Perseus and its funders as quoted above, and pass on the same share-alike terms.

## How roots are matched, and coverage

Perseus stores Arabic in a Buckwalter transliteration; we decode each article's root key to Arabic and match it to the corpus's roots by a folded radical fingerprint (`pipeline/lexicon.py`). Coverage is uneven because Lane died before finishing and the later letters were assembled posthumously by Stanley Lane-Poole; the exact fraction of roots with an entry, and every root without one, are listed in `coverage-report.md`. Where a root has no entry, the root page says so explicitly.
