{{Csdoc|lua|lua=yes}}
The '''Citation''' template generates a citation for a book, periodical, contribution in a collective work, patent, or a web page. It determines the citation type by examining which parameters are used. As with other citation templates, this template can be used either in a footnote (between {{Tag|ref}} tags) or in a section that lists sources.  This template uses the same [[WP:Lua|Lua]] code as [[Help:Citation Style 1|citation style 1 (CS1)]] templates with parameters to change the displayed format to [[Help:Citation Style 2|citation style 2 (CS2)]].

If the correct parameters are used, this template produces output identical to that of the Cite templates, such as {{Tl|Cite book}} and {{Tl|Cite web}}, with one important exception: By default, this Citation template uses commas in places where the Cite templates use periods (full stops) by default; either type of template can use periods (full stops) or commas by using an optional parameter. Also, this template by default generates anchors for [[Harvard reference|Harvard reference]]s whereas the Cite templates by default do not (although they can be made to do so). 

Regardless of which citation templates are used or even if none are used at all, all citations should have the same format throughout an article in the saved, rendered text.

Note: All parameter names must be [[Lowercase|lowercase]].

==Simple citations==
This section covers the most commonly used parameters. You can copy the horizontal form or vertical form below and then add in extra parameters from the full list. Spacing and ordering of the parameters within the template is irrelevant and does not affect the final, rendered text.

* '''last''': The author's surname or last name. Don't use with the '''author''' parameter.
* '''first''': The author's first or given name(s).
* '''year''': Year of authorship or publication. Mandatory for use with links from [[:Template:Harvard citation]], unless {{Para|date}} specifies both month and year.
* '''title''': Title of the work. Mandatory for web references.
* '''publisher''': The name of the publisher. Omit terms such as ''Publishers'', ''Co.'', ''Inc.'', ''Ltd.'', etc., but retain the words ''Books'' or ''Press''. Not normally included where the publication is a periodical which has its own Wikipedia article (e.g. ''[[Newsweek]]'', ''[[Billboard (magazine)|Billboard]]'').
** '''publication-place''' (or '''place''' or '''location'''): The city of publication. If more than one town/city is listed on the title page, give the first one or the location of the publisher's head office. Omit when the publication is a periodical whose name specifies the location (e.g. ''The New York Times'', ''The Times of India'')
* '''page''': For use when one page is cited. Adds "p." before the page number. Do not use with '''pages'''.
* '''url''': A [[Uniform resource locator|url]] of an online location where the item can be found. If the url includes double quotes, these must be encoded as "%22".
** '''accessdate''': Date<ref group = "n" name = "dates" /> when the url was accessed.

==Anchored citations==
This template can generate a citation that can be combined with [[WP:CITESHORT|shortened footnotes]] or [[Wikipedia:Parenthetical referencing|parenthetical referencing]]. It does this by creating an [[HTML element#Anchor|HTML anchor]] containing an ID. The special parameter {{Para|ref|harv}} generates an ID suitable for [[Harvard referencing]] templates such as {{Tl|harv}} as specified in the next section; this is the default for the {{Tl|citation}} template. 

To disable anchor generation, specify {{Para|ref|none}} (in contrast, other Cite templates such as {{Tl|cite book}} and {{Tl|cite news}} do not create an anchor by default). You can also specify the ID directly, using the {{Para|ref|<var>ID</var>}} parameter. For example, suppose an article's ''References'' section contains the markup:
* <code><nowiki>{{Citation |author=Sigmund Freud |title=Civilization and Its Discontents |year=1930 |ref=CivDis}}</nowiki></code>
which generates the citation:
* {{Citation |author=Sigmund Freud |title=Civilization and Its Discontents |year=1930 |ref=CivDis}}
Then, the markup "<code><nowiki>([[#CivDis|Freud 1930]])</nowiki></code>" generates a parenthetical reference "([[#CivDis|Freud 1930]])" containing a wikilink to the citation (try clicking on the wikilink).

===Anchors for Harvard referencing templates===
IDs compatible with Harvard referencing templates such as {{Tl|harv}} are computed from the last names of the authors (or editors, if no authors are given) and the year of the cited source. For example, the markup "<code><nowiki>{{Harv|Wright|Evans|1851|p=ix}}</nowiki></code>" generates the Harvard reference "{{Harv|Wright|Evans|1851|p=ix}}", which wikilinks to the citation whose markup and appearance are shown below:
* <code><nowiki>{{Citation |last1=Wright |first1=Thomas |last2=Evans |first2=R. H. |title=Historical and Descriptive Account of the Caricatures of James Gillray |location=London |publisher=Henry G. Bohn |year=1851 |oclc=59510372}}</nowiki></code>
* {{Citation |last1=Wright |first1=Thomas |last2=Evans |first2=R. H. |title=Historical and Descriptive Account of the Caricatures of James Gillray |location=London |publisher=Henry G. Bohn |year=1851 |oclc=59510372}}
In this example the {{Tl|citation}} template defines, and the {{Tl|harv}} template uses, the HTML ID "<code>CITEREFWrightEvans1851</code>", composed by concatenating the string "<code>CITEREF</code>" with the last names of the authors and the year. The {{Tl|harvid}} template can be used to generate such IDs, for example, <code><nowiki>{{Harvid|Wright|Evans|1851}}</nowiki></code> generates "<code>{{Harvid|Wright|Evans|1851}}</code>".

Related methods which leave only a number in the text are to use the {{Tl|harvnb}} template enclosed in the <nowiki><ref></ref></nowiki> html code, or to use the {{Tl|sfn}} template alone. The example above would be <code><nowiki><ref>{{Harvnb|Wright|Evans|1851|p=ix}}</ref></nowiki></code> or <code><nowiki>{{Sfn|Wright|Evans|1851|p=ix}}</nowiki></code> both of which generate a footnote, such as
:17. {{Harvnb|Wright|Evans|1851|p=ix}}

The names of only the first four authors are used; other author names are not concatenated to the ID. If no author names are given, editor names are used instead. For [[#Citing patents|patents]], inventor names are used instead of authors or editors. If these names are not given, this template does not generate an anchor.

Last names are used, as specified by the parameters {{Para|last1}} (or {{Para|last}}), {{Para|last2}}, {{Para|last3}}, and {{Para|last4}}, and similarly for {{Para|editor1-last}} etc. and for {{Para|inventor1-last}} etc. If a full name is given but no last name is specified, this template falls back on the full name, but this usage is not recommended. For example, in "<code><nowiki>{{Citation | author = Sigmund Freud | title = The Ego and the Id | year = 1923}}</nowiki></code>" no last name is given, so this citation cannot be combined with the Harvard reference "<code><nowiki>{{Harv|Freud|1923}}</nowiki></code>". To make these {{Tl|citation}} and {{Tl|harv}} invocations compatible, either replace "{{Para|author|Sigmund Freud}}" with "{{Para|first|Sigmund}} {{Para|last|Freud}}", or add "{{Para|ref|<nowiki>{{Harvid|Freud|1923}}</nowiki>}}" to the {{Tl|citation}} invocation, or add the same ref parameter (say, "{{Para|ref|EgoId}}") to both the {{Tl|citation}} and the {{Tl|harv}} invocations.

Similarly, the year is used, as specified by {{Para|year}}. If no year is given, this template attempts to derive the year from {{Para|date}} (or, if no date is given, from {{Para|publication-date}}) by applying the [[mw:Help:Extension:ParserFunctions##time|MediaWiki §&nbsp;Time function]]. This heuristic works with many common date formats (American, International and [[ISO 8601#Calendar dates|ISO 8601 standard format]] YYYY-MM-DD as listed in [[WP:MOS]]), but may not work as expected with other formats, so when in doubt it may be safer to use {{Para|year}}. Note that if only a year, say 2005, is known you must use {{Para|year|2005}} rather than {{Para|date|2005}}.

===IDs must be unique===
Names, years, and hand-specified IDs must be chosen so that the IDs are unique within a page; otherwise the HTML will not conform to the W3C standards, and any references to the citations will not work reliably. For example, suppose a page contains the following two citations with {{Tl|harv}}-compatible IDs:
* {{Citation |last1=Montes |first1=G. |last2=Halterman |first2=J. S. |year=2008a |journal=Pediatrics |volume=121 |issue=4 |pages=e821–e826 |title=Association of Childhood Autism Spectrum Disorders and Loss of Family Income |doi=10.1542/peds.2007-1594 |pmid=18381511 |url= http://pediatrics.aappublications.org/cgi/content/full/121/4/e821 }}
* {{Citation |last1=Montes |first1=G. |last2=Halterman |first2=J. S. |year=2008b |journal=Pediatrics |volume=122 |issue=1 |pages=e202–e208 |title=Child Care Problems and Employment Among Families with Preschool-aged Children with Autism in the United States |doi=10.1542/peds.2007-3037 |pmid=18595965 |url= http://pediatrics.aappublications.org/cgi/content/full/122/1/e202 }}

If these citations were altered to say "2008" rather than "2008a" and "2008b", the resulting page would not work, because the two different citations would both attempt to use the ID "<code>CITEREFMontesHalterman2008</code>". To avoid this problem, distinguish the citations by appending suffixes to the years, e.g. "{{Para|year|2008a}}" and "{{Para|year|2008b}}", as was done above. Any Harvard references to these citations should use years with the same suffixes.

It is good practice to verify that a page does not contain duplicate IDs by using the [[W3C Markup Validation Service]]; see ''[[#External links|External links]]''.

==Dates==
{{Reflist|group="n"|refs=<ref name="dates" group="n">The format of dates in the references of an article should use consistent and unambiguous styles. Example formats used in Wikipedia citations include:
* ''2009''
* ''2009-09-14'' ([[ISO 8601#Calendar dates|ISO 8601 standard format]]: YYYY-MM-DD)
* ''14 September 2009''
* ''September 14, 2009'' (with comma)
* ''September 2009''

Dates should not be linked (say, to a Wikipedia article of the same name) in references.

Please see [[Wikipedia:Manual of Style (dates and numbers)#Dates|Wikipedia:Manual of Style (dates and numbers) §&nbsp;Dates]] for more guidance about formatting dates.

==Tools==
See [[Wikipedia:Citing sources#Citation templates and tools|Wikipedia:Citing sources §&nbsp;Citation templates and tools]] for a list of tools that can help create a reference in the "citation" format.
