Terms of Use & Copyright Notice

Guidelines governing the use of the Lumen Libri digital reading room, public-domain literary texts, and original editorial content.

1. Acceptance of Terms

By accessing and using Lumen Libri (https://lumenlibri.com/), you agree to comply with and be bound by these Terms of Use. If you do not agree to these terms, please discontinue use of the site.

2. Public-Domain Works vs. Original Editorial Content

Lumen Libri combines two distinct categories of material:

  • Public-Domain Literary Texts: The underlying historical works featured in our reading room—specifically Samuel Moore’s 1888 English translation of Karl Marx and Friedrich Engels’s The Communist Manifesto, Dr. Lionel Giles’s 1910 translation of Sun Tzŭ’s The Art of War, and Ömer Seyfettin’s 1918 Turkish short story Velinimet—are in the public domain worldwide. You are free to read, quote, and study these historical texts without restriction.
  • Original Editorial Commentary, Design & Code: The Lumen Libri user interface, custom SVG book cover illustrations, original critical study guides, curatorial essays, pagination software, and brand assets are the intellectual property of Lumen Libri and are protected by applicable copyright laws.

3. Personal Bookshelf Feature

The "Add a book" feature allows you to store personal book notes and reading passages locally in your browser. You are solely responsible for any text you paste into your local browser storage, and such content remains private to your device.

4. Disclaimer of Warranties

Lumen Libri and its literary texts and study guides are provided on an "as is" and "as available" basis for educational, literary, and historical research purposes. While we strive for philological and typographic accuracy, we make no warranties regarding completeness or uninterrupted availability.
