- url: URL of an online location where the text of the publication 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.
#ixzz2rBr3aO94or Template:Nowrap. Template:Hatnote inline Do not link to any commercial booksellers, such as Amazon.com; use Template:Para or Template:Para 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.Template:R 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. See "Automatic date formatting" above for details about interaction with Template:Tlx and Template:Tlx. 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 Template:Hatnote inline, WebCite Template:Hatnote inline and archive.is Template:Hatnote inline; requires archive-date and url. By default (overridden by Template:Para) 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.Template:R Do not wikilink; templated dates are discouraged. See "Automatic date formatting" above for details about interaction with Template:Tlx and Template:Tlx. 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 Template:Para. When the URL is still live, but pre-emptively archived, then set Template:Para; 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 Template:Para or Template:Para suppresses display of the original URL (but Template:Para and Template:Para are still required).
- template-doc-demo: The archive parameters will be error-checked to ensure that all the required parameters are included, or else Template:Tl 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:Para 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.
