Wikipedia is not a mirror of public domain or other source material. In Wikipedia articles, quotes of any original texts being discussed should be relevant to the discussion (or illustrative of style) and should be kept to an appropriate length.    If out of copyright, shorter texts such as short poems and national anthems are usually included in their article, e.g. Ozymandias, but longer texts are best summarised with the full text placed on Wikisource, or given as an external link.   If the work is in copyright, then be careful to limit the amount quoted, do not place it on Wikisource, and only link to websites containing it if they have a right to do so, for instance, a band's official site may contain lyrics or videos for one of their songs. These could be linked to, but we must not link to an unauthorized copy of their video on YouTube, or to a site infringing the copyright on their lyrics.  Summarise, quote from and link to Avoid including entire texts of treaties, press releases, speeches or lengthy quotations, and so on. In an article of a treaty, for example, summarize the treaty and then provide an external link (or, if the treaty is on Wikisource, an interwiki link) to the actual treaty. Smaller sources and samples are acceptable in articles.   Examples of combining Wikipedia and Wikisource:  Christ the Lord Is Risen Today has an encyclopedia article on Wikipedia about the hymn and the text of the hymn on Wikisource (as well as the text of a related hymn). In a more extended article, a verse or two might be quoted for discussion.  Gunga Din has an encyclopedia article on Wikipedia about the poem and the text of the poem on Wikisource. The short Wikipedia article quotes the famous last line, but not the entire poem. The 1793 law prohibiting slavery in Upper Canada has an encyclopedia article on Wikipedia about the law and the text of the law on Wikisource. The content of the act is summarised in the Wikipedia article, but not quoted in full.  Wikisource has specific repositories for certain types of primary source texts, such as, for example, constitutions (Wikisource:Wikisource:Constitutional documents) and national anthems (Wikisource:Wikisource:National anthems), which can contain translations of the source text into multiple languages (including translations of the source text from its original language into English).   Fair use of copyrighted primary sources   Fair use allows us to quote short sections from copyrighted primary sources, if relevant to explaining the topic of an article. For instance, we can quote a sentence or two from a movie review in an article on the movie, or quote a small portion of a modern poem in order to illustrate its style. In all such cases, be sure to properly attribute the work to its original author, and state where it was published. When writing an article at Wikipedia about a copyrighted primary source, please follow Wikipedia: Fair use -Fair use policy carefully before including quotes from the copyrighted source.   Transwiki to Wikisource: License and copyright If moving text from Wikipedia to Wikisource, make sure that the work is free of copyright, or appropriately licensed.   For example, older lyrics of the Internationale have entered the public domain, but the modern version by Billy Bragg is still copyrighted, so quotes from it would need to be short, relevant, properly credited to Billy Bragg, and could not be used on Wikisource except as part of an appropriately licensed primary text on Billy Bragg. Per Wikisource's inclusion policy, the text discussing Billy Bragg would also have needed to pass through editorial oversight or peer review.
