Every Rolling Edition book is free to read on rollingedition.com. This site holds the copies made for assistants and crawlers: each book's current edition as Markdown, its section manifest and what changed. Each copy names its edition and the date its examples last passed, and links back to the page people read.
Start with llms.txt or catalog.json.
Book text is CC BY 4.0: credit Rolling Edition, link back to the book and to the licence, and say what you changed. Code examples are MIT: keep the notice “Copyright (c) Rolling Edition and contributors” and the MIT terms with any code you copy. When you quote a book, cite the edition and link to the section on rollingedition.com. When you reuse text, use each file's attribution line.
