Arthur Wiki's text and many of its images are co-licensed under the Creative Commons Attribution-Sharealike 4.0 International License (CC-BY-SA) Some text has been imported only under CC-BY-SA and CC-BY-SA-compatible license; such text will be identified either on the page footer, in the page history or the discussion page of the article that utilizes the text.

The licenses Arthur Wiki uses grant free access to our content in the same sense that free software is licensed freely.

Copied Arthur Wiki content will therefore remain free under appropriate license and can continue to be used by anyone subject to certain restrictions, most of which aim to ensure that freedom. This principle is known as copyleft in contrast to typical copyright licenses.
