Template:Citation Style documentation/url

• url: URL of an online location where the text of the publication can be found. Cannot be used if title is wikilinked. If applicable, the link may point to the specific page(s) referenced. Remove tracking parameters from URLs, e.g. #ixzz2rBr3aO94 or ?utm_source=google&utm_medium=...&utm_term=...&utm_campaign=....
  See WP:PAGELINKS. Do not link to any commercial booksellers, such as Amazon.com. Invalid URLs, including those containing spaces, will result in an error message.

  • access-date: Full date when the content pointed to by url was last verified to support the text in the article; do not wikilink; requires url; use the same format as other access and archive dates in the citations.Template:R Not required for linked documents that do not change. For example, access-date is not required for links to copies of published research papers accessed via DOI or a published book, but should be used for links to news articles on commercial websites (these can change from time to time, even if they are also published in a physical medium). Note that access-date is the date that the URL was checked to not just be working, but to support the assertion being cited (which the current version of the page may not do). Can be hidden or styled by registered editors. Alias: accessdate.
  • archive-url: The URL of an archived copy of a web page if the original URL is no longer available. Typically used to refer to services such as WebCite
    (see Wikipedia:Using WebCite) and Internet Archive

    (see Wikipedia:Using the Wayback Machine); requires archive-date and url. By default (overridden by |dead-url=no) the archived link is displayed first, with the original link at the end. Alias: archiveurl.

    • archive-date: Date when the original URL was archived; preceded in display by default text "archived from the original on". Use the same format as other access and archive dates in the citations. This does not necessarily have to be the same format that was used for citing publication dates.Template:R Do not wikilink. Alias: archivedate.
    • dead-url: the default value of this optional parameter, if omitted, is |dead-url=yes. Equivalent values are y or true. When the URL is still live, but pre-emptively archived, then set |dead-url=no; this changes the display order, with the title retaining the original link and the archive linked at the end. When the original URL has been usurped for the purposes of spam, advertising, or is otherwise unsuitable, setting |dead-url=unfit or |dead-url=usurped suppresses display of the original URL (but |url= is still required). Alias: deadurl.
  • template-doc-demo: The archive parameters will be error-checked to ensure that all the required parameters are included, or else {{citation error}} is invoked. With errors, main, help and template pages are placed into one of the subcategories of Category:Articles with incorrect citation syntax. Set |template-doc-demo=true to disable categorization; mainly used for documentation where the error is demonstrated.
• format: Format of the work referred to by url; for example: PDF, DOC, or XLS; displayed in parentheses after title. (For media format, use type.) HTML is implied and should not be specified. Automatically added when a PDF icon is displayed. Does not change the external link icon. Note: External link icons do not include alt text; thus, they do not add format information for the visually impaired.
