Wikipedia:Citation and reuse of Wikipedia content

Article

May 23, 2022

Wikipedia is designed to be reused and disseminated; it is in this and only in this that it is a "free" encyclopedia. But this reuse must be done according to the rules of the "Creative Attribution-ShareAlike 3.0 Unported License" (CC BY-SA 3.0). For the reuse, copying or modification of all or part of the text of an article, you must: indicate that the reused, copied or modified content is under CC BY-SA 3.0, allow the identification of the authors by giving a web address to the Wikipedia article, or by giving a list of authors (paternity), indicate whether you have modified the original Wikipedia content, leave all derivative works under the same license (share alike). An automated tool, "Cite this page", accessible in the left column of the page of each article in the "toolbox" and at the de-page of all articles, allows you to get all the ways to correctly credit a reuse of a Wikipedia article. You can also access this tool using the following button: Quote a page The official and detailed terms of use for Wikipedia content can be found at: Terms of Use under “7. Content Licenses - g. Reuse”. Important preliminary remark: Wikimedia Foundation, host of Wikipedia, does not hold rights on the encyclopedic texts and images that it hosts (with the exception of its own logos). Consequently, it cannot issue a reproduction authorization. It is therefore useless to write to Wikipedia's contact addresses to request permission to reproduce (except in very special cases, such as the Wikipedia logo, protected by copyright and trademark law).

Short quote

As part of the right of short quotation, you are not obliged to submit to all the obligations of CC BY-SA 3.0: you only need to mention the author and the source. You will find out how to cite a Wikipedia article using the Special:Cite tool. On the other hand, the obligations of CC BY-SA 3.0 are rigorous for: full copies; long quotes; quotes that are not made: "for the purpose of criticism, controversy, review, teaching, or in scientific work, in accordance with the honest practices of the profession" (Belgium: law of June 30, 1994), that does not constitute "fair use [...] for purposes of criticism or review" (Canada: Copyright Act Section 29.1), which are not used for the "critical, polemical, educational, scientific or informative nature of the work in which they are incorporated" (France: Intellectual Property Code article 122-5) or which do not serve as “commentary, reference or demonstration” (Switzerland: federal law on copyright and related rights).
