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. Do not link to any commercial booksellers such as Amazon.com; see WP:BOOKLINKS.
  • accessdate: Full date when URL was accessed; use the same format as other dates in in the article; do not wikilink.
  • archiveurl: The URL of an archived copy of a web page, if or in case the url becomes unavailable. Typically used to refer to services like WebCite and the Internet Archive; requires archivedate.
    • archivedate: Date when the item was archived; use the same format as other dates in in the article; do not wikilink; requires archiveurl.
    • deadurl: To change the order with the title retaining the original link and the archive linked at the end, set |deadurl=no.
  • template doc demo: The archive parameters have error checking to ensure that all the required parameters are included, else {{citation error}} is invoked. On errors, main, help and template pages are placed into 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; examples: PDF, DOC, XLS; HTML is implied and should not be specified; displayed in parentheses after title.

URLs must begin with a supported URI scheme. http:// and https:// will be supported by all browsers; however, ftp://, gopher://, irc://, ircs://, mailto: and news: may require a plug-in or an external application and should normally be avoided. IPv6 host-names are currently not supported.

If URLs in citation template parameters contain certain characters, then they will not display and link correctly. Those characters need to be percent-encoded. For example, a space must be replaced by %20. To encode the URL, replace the following characters with:

sp	"	'	<	>	[	]	{	|	}
%20	%22	%27	%3c	%3e	%5b	%5d	%7b	%7c	%7d

Single apostrophes do not need to be encoded; however, unencoded multiples will be parsed as italic or bold markup. Single curly closing braces also do not need to be encoded; however, an unencoded pair will be parsed as the double closing braces for the template transclusion.
