Apple Lisa 2: Difference between revisions
Collapse duplicated <ref name=...> definitions to a single definition with the rest self-closing (duplicate definitions render as a visible red cite error) |
House rule: reword in-article correction narratives so they describe the claim in circulation and what the source says, rather than the page's own edit history. The corrections themselves are recorded in the edit summaries |
