WikiBlame is an online browser-based tool for searching the revision history of a MediaWiki-based wiki for a text string to identify the author of a particular change to the page.

WikiBlame is available on each page by selecting View HistoryRevision history search.


Integration of WikiBlame in en.wp
  • search the revision history of a wiki article for a plain text string
  • search based on simple wiki markup such as links, section headings and templates
  • linear search or binary search
  • option to specify a start date for the search


  • Establish when and by whom vandalism, copyright violations or promotional material was added to an article. This allows users to see whether the problematic editor made other undetected changes at the same time.
  • WikiBlame can also be used for other types of searches:
    • It can find out who added a quotation without an inline citation. If the editor is still active, the editor can be asked if he or she remembers where the quote was read, so that an inline citation can be added to the article.
    • It can find an editor who added a short citation without adding the corresponding long citation to a references section. This is a fairly common mistake which is made when editors copy text from one article to another. If the editor is still active they can be contacted to ask from whence the copy came, or the text found by WikiBlame can be searched for in other Wikipedia articles to see if the long citation is available in another article.
    • It can find unsigned entries on a talk pages so that the editor's signature can attributed (see WP:TALK "Attributing unsigned comments")
    • It can also be used to fix these errors (by searching for the name of the reference; e.g. "name=Oxford"):
      Cite error: The named reference Oxford was invoked but never defined (see the help page).
which occur when someone deletes the original reference which is still used by its name somewhere else in an article.
