Template:Citation Style documentation/url


 * url: URL of an online location where the named by title 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.   or .  Do not link to any commercial booksellers, such as Amazon.com; use ISBN or OCLC to provide neutral search links for books. 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. Not required for linked documents that do not change. For example, access-date is required for online sources, such as personal websites, that do not have a publication date; see WP:CITEWEB. Access dates are not required for links to published research papers, published books, or news articles with publication dates. Note that access-date is the date that the URL was found to be working and to support the text being cited. Can be hidden or styled by registered editors. Alias: accessdate.
 * archive-url: The URL of an archived snapshot of a web page. Typically used to refer to services such as Internet Archive, WebCite and archive.is ; requires archive-date and url. By default (overridden by live, or the equivalent no, deprecated but still used in many articles) the archived link is displayed first, with the original link at the end. Alias: archiveurl.
 * archive-date: Archive-service snapshot-date; 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. Do not wikilink; templated dates are discouraged. Alias: archivedate.
 * url-status: this optional parameter is ignored if archive-url is not set. If omitted, or with null value, the default value is dead. When the URL is still live, but pre-emptively archived, then set live; 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 unfit or usurped suppresses display of the original URL (but url and archive-url are still required).
 * dead-url (deprecated; replaced by url-status above): Functionality is identical to that of url-status: yes or null is the same as dead; no is the same as live; similarly for usurped or unfit. Global replacement of, for example, no with live in CS1 and CS2 templates is safe (but be careful with null value "dead-url").
 * 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 true to disable categorization; mainly used for documentation where the error is demonstrated. Alias: no-cat.
 * 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.
