When at least one author is listed, and edits have been made by additional users (regardless of fulfilling the criteria above), ''et al.'' should be added to the author list, linking to the "View history" page of the article, in order to denote that the listed author(s) is not the only contributor(s).
When a substantial amount of content (with no strict threshold but often corresponding to about a section) is copied or closely paraphrased from a source with a Creative Commons license that includes attribution (such as [https://creativecommons.org/licenses/by/4.0/ CC-BY]), the authors of that article should be mentioned at top, such as "Authors of integrated Creative Commons article" followed by a [[#References|reference]] to that article. If only minor portions of such article is integrated, it is enough to mention the authors by a reference at the integrated material.
