Wikipedia:WikiProject WikiFundi Content/Help:Page history

A page history shows the order in which changes were made to any editable wiki page, the difference between any two versions, and a menu of special external tools. A page history is sometimes called revision history or edit history. It is accessed by clicking the "View history" tab at the top of the page.

The page history contains a list of the page's previous revisions, including the date and time (in UTC) of each edit, the username or IP address of the user who made it, and their edit summary. For example, the page history for this help page shows that it was first created on September 20, 2004, and that it has been changed more than 500 times during the last ten years.

On a history page:
 * All past changes to the page in question are listed in reverse-chronological order.
 * To view a specific version, click a date.
 * To compare an old version with the current version, go to the old version, click cur.
 * To compare a version with its predecessor, click prev.
 * To compare two specific versions, click the left-column radio button of the older version and the right-column radio button of the newer version, and then click the "Compare selected versions" button.
 * To undo (revert) your own or someone else's edit, click the "undo" link.
