Introduction
All editable pages have an associated page history, which consists of the old versions of the wikitext, as well as a record of the date and time of every edit, the name of the user who wrote it, and their edit summary. Access the page history by clicking the “history” tab at the top of the page. This may also be referred to as the revision history or edit history.
Linking to a specific version of a page
It is occasionally useful to link to a specific version of an article (a snapshot of it). For example, one might have done a review of an article and want to indicate which particular version was reviewed.
If the version is not the current version, one can use the page history to view the old version of the page. The URL of this old version is suitable for use to permanently reference this version, and can usually be obtained from the browser’s location bar.
Reverting a page
If your new pages edits aren’t to your liking, don’t panic; you can ‘revert’ or restore the page to any previous version.
