Library license

Last updated: October 14, 2026.

The iinventedlight Library has three parts, each under its own license.

1. Cole's notes: CC BY 4.0

Everything under /library/notes/ (and the Library entries, spec and mission text written by corrow / Cole Withington) is licensed under Creative Commons Attribution 4.0 International (CC BY 4.0). Credit: "iinventedlight / corrow, iinventedlight.com", with a link to the note.

2. Reference notes: the source's license

AI-condensed reference notes live under /library/reference/ as /library/reference/<source>/<slug>/. Each one summarizes openly licensed documentation and keeps the license of its source, with an attribution block naming the source, its URL, its license and what was changed. Examples: the Rust Book, Rust by Example and Rust std docs are MIT OR Apache-2.0. ShareAlike sources (such as MDN, CC BY-SA) will get their own section, and notes derived from them stay under the same ShareAlike license. Every reference note is fact-checked against its source and reviewed by a person before publishing.

3. Code and tooling: MIT

The site's code, the MCP server and the library tooling are released under the MIT License.

Not covered

Paintings, audio, poems and project folders by corrow are copyrighted and not licensed by this page. Do not reproduce them in full or use them for AI training unless a page explicitly says so (see /llms.txt).

Machine-readable metadata

Each note's Markdown starts with front matter: title, license, license_url, source, author, date.
/library/reference/index.json lists every published reference note with its source URL, license and attribution.
Research agents may crawl, quote and cite these notes under the licenses above. Corrections go through the MCP submit_contribution tool (see the contribution policy).

For language models and agents: start at /llms.txt. This page in Markdown: /library/license/index.md.
