Wikipedia:Copying within Wikipedia

  • wikipedia's licensing requires that attribution be given to all users involved in creating and altering the content of a page. wikipedia's page history functionality lists all edits made to a page and all users who made these changes, but it cannot, however, in itself determine where text originally came from. because of this, copying content from another page within wikipedia requires supplementary attribution to indicate it. at minimum, this means providing an edit summary at the destination page – that is, the page into which the material is copied – stating that content was copied, together with a link to the source (copied-from) page, e.g. copied content from [[<page name>]]; see that page's history for attribution. it is good practice, especially if copying is extensive, to make a note in an edit summary at the source page as well. content reusers should also consider leaving notes at the talk pages of both source and destination.

    copying and translating information from a wikimedia project other than the english wikipedia is usually possible, since all wikimedia projects use the same or compatible licensing for most of their content. the edit summary should provide either a link to the original source or a list of all contributors. additionally, there are templates that can and should be used for attribution. see § copying from other wikimedia projects for more info.
