{{for2|the {{fake citation needed template|tl|citation needed

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.

If invoked with the right parameters, this template produces output identical to that of the Cite templates, such as {{Cite book}}

and {{Cite web}}

. The default behavior sometimes differs from that of the Cite templates; for example, this template by default generates anchors for Harvard references whereas the Cite templates do not (although they can be made to do so), and this template by default uses commas to separate some fields that the Cite templates separate with periods (full stops).

The template should be inserted after punctuation, such as a period or comma.

All parameter names are lowercase.

Simple citation

This template gives the most commonly used attributes. You can copy the horizontal form or vertical form below and then add in extra attributes from the full list. Spacing and ordering is irrelevant.

{{Citation |last= |first= |year= |title= |publisher= |publication-place= |page= |url= |accessdate= }}

{{Citation | last = | first = | year = | title = | publisher = | publication-place = | page = | url = | accessdate = }}

• last: The author's surname or last name. Don't use with author.
• 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 |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 when the url was accessed.

Example

{{Citation | last = Turner | first = Orsamus | title = History of the pioneer settlement of Phelps and Gorham's purchase, and Morris' reserve | publisher = William Alling | place = Rochester, New York | year = 1851 | id = {{OL|7120924W}} }}

Turner, Orsamus (1851), History of the pioneer settlement of Phelps and Gorham's purchase, and Morris' reserve, Rochester, New York: William Alling,

Full citation parameters

These can be used for all types of publication except patents. All are optional and indentation is used simply to group related items — these may be mutually exclusive where indicated. Some hyphenated names can also be placed without hyphens.

If no authors: Editors appear before the included work; a single editor is followed by "ed."; multiple editors are followed by "eds.";

</noinclude> more than three editors will be followed by "et al., eds."

Title

• title: Title of source. Can be wikilinked to an existing Wikipedia article or url may be used to add an external link, but not both. Displays in italics.
  • trans_title: English translation of the title if the source cited is in a foreign language. Displays in square brackets after title; if url is defined, then trans_title is included in the link. Use of the language parameter is recommended.

Titles containing certain characters will display and link incorrectly unless those characters are encoded.

newline	[	]	|
space	[	]	|

• chapter: The chapter heading of the source. May be wikilinked or may use chapter-url, but not both. Displays in quotes.
  • trans_chapter: English translation of the chapter heading, if the source cited is in a foreign language. Displays in square brackets after the chapter field; if chapter-url is defined, then trans_chapter is included in the link. Use of the language parameter is recommended.

• language: The language the source is written in, if not English. Displays in parentheses with "in" before the language name. Use the full language name or ISO 639-1 code; use of ISO 639-1 also adds appropriate language categorization; do not use icons or templates.

Date

• date: Date of source being referenced. Can be full date (day, month, and year) or partial date (month and year, season and year, year). Use same format as other publication dates in the citations.

Required when year is used to disambiguate {{sfn}} links to multiple-work citations by the same author in the same year.[more] Do not wikilink. Displays after the authors and is enclosed in parentheses. If there is no author, then displays after publisher.

• OR:
  • year: Year of source being referenced. Required with some types of {{sfn}} citations;^[more] otherwise use date.

(deprecated) Name of the month or season of publication. Use date instead.

• • origyear: Original publication year; displays after the date or year. For clarity, please supply specifics. For example: |origyear=First published 1859 or |origyear=Composed 1904.

Periodical

• work: Name of the source periodical; may be wikilinked if relevant. Displays in italics. Aliases: journal, newspaper, magazine, periodical.
  • issue: When the publication is one of a series that is published periodically.

When set, work changes the formatting of other parameters:

title is not italicized and is enclosed in quotes.

chapter is italicized and is not enclosed in quotes.

location and publisher are enclosed in parentheses.

page and pages do not show p. or pp.

edition does not display.

type does not display.

Publisher

• publisher: Name of publisher; may be wikilinked if relevant. The publisher is the company that publishes the work being cited. Do not use the publisher parameter for the name of a work (e.g., a book, encyclopedia, newspaper, magazine, journal, website). Not normally used for periodicals. Corporate designations such as "Ltd", "Inc" or "GmbH" are not usually included. Omit where the publisher's name is substantially the same as the name of the work (for example, The New York Times Co. publishes The New York Times newspaper, so there is no reason to name the publisher). Displays after title; if work is defined, then publisher is enclosed in parentheses.
• place: Geographical place of publication; generally not wikilinked; omit when the name of the work includes the location; examples: The Boston Globe, The Times of India. Displays after the title; if work is defined, then location is enclosed in parentheses. Alias: location
• publication-place: If any one of publication-place, place or location are defined, then the location shows after the title; if publication-place and place or location are defined, then place or location are shown before the title prefixed with "written at" and publication-place is shown after the title.
• publication-date: Date of publication when different from the date the work was written. Displays only if year or date are defined and only if different, else publication-date is used and displayed as date. Use the same format as other dates in the article; do not wikilink. Follows publisher; if work is not defined, then publication-date is preceded by "published" and enclosed in parenthesis.

Edition, series, volume

• edition: When the publication has more than one edition; for example: "2nd", "Revised" etc. Displays " ed." after this field, so |edition=2nd produces "2nd ed." Does not display if a periodical field is defined.

• series or version: When the source is part of a series, such as a book series or a journal where the issue numbering has restarted.

• volume: For one publication published in several volumes. Displays after the title and series fields; displays in bold— if bolding is not desired, then include the volume information in the title field.

In-source locations

• page: The number of a single page in the source that supports the content. Use either |page= or |pages=, but not both. Displays preceded by p. unless |nopp=y.
• OR: pages: A range of pages in the source that supports the content. Use either |page= or |pages=, but not both. Separate using an en dash (–); separate non-sequential pages with a comma (,); do not use to indicate the total number of pages in the source. Displays preceded by pp. unless |nopp=y. Hyphens are automatically converted to en dashes; if hyphens are appropriate, for example: pp. 3-1–3-15, use |at=.
  • nopp: Set to y to suppress the p. or pp. notations where this is inappropriate; for example, where |page=Front cover.
• OR: at: For sources where a page number is inappropriate or insufficient. Overridden by |page= or |pages=. Use only one of |page=, |pages=, or |at=.

Examples: page (p.) or pages (pp.); section (sec.), column (col.), paragraph (para.); track; hours, minutes and seconds; act, scene, canto, book, part, folio, stanza, back cover, liner notes, indicia, colophon, dust jacket, verse.

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:PAGELINKS.
  • accessdate: Full date when original URL was accessed; use the same format as other access and archive dates in the citations.

Do not wikilink. Not required for web pages or linked documents that do not change; mainly for use of web pages that change frequently or have no publication date. Can be Help:Citation Style 1/accessdate|hidden or styled by registered editors.

• • archiveurl: The URL of an Web archiving|archived copy of a web page, if or in case the url becomes unavailable. Typically used to refer to services like WebCite (see: Wikipedia:Using WebCite) and Internet Archive (see: Wikipedia:Using the Wayback Machine); requires archivedate.
    • archivedate: Date when the original URL was archived; preceded by default text "archived from the original on". Use the same format as other access and archive dates in the citations.

Do not wikilink.

• • • deadurl: When the URL is still live, but preemptively archived, then set |deadurl=no. This changes the display order with the title retaining the original link and the archive linked at the end.
  • 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 :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. HTML is implied and should not be specified. Does not change the Help:External link icons|external link icon. Note: External link icons do not include Wikipedia:ALT|alt text; thus, they do not add format information for the visually impaired.

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: will 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	%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.

Anchor

• ref: ID for anchor. By default, anchors are always generated. The ordinary nonempty value |ref=ID generates an anchor with the given ID; such a linkable reference can be made the target of Wikipedia:Citing sources/Further considerations#Wikilinks to full references|wikilinks to full references]], especially useful in short citations like Wikipedia:Citing sources#Shortened footnotes|shortened notes]] and Wikipedia:Parenthetical referencing|parenthetical referencing]].

Identifiers

• id: A unique identifier, used where none of the specialized identifiers are applicable; wikilink or use a template as applicable.

These identifiers create links and are designed to accept a single value. Using multiple values or other text will break the link and/or invalidate the identifier.

• arxiv: arXiv identifier; for example: arxiv=hep-th/9205027
• asin: Amazon Standard Identification Number
  • asin-tld: ASIN top-level domain for Amazon sites other than the US; valid values: ca, cn, co.jp, co.uk, de, es, fr, it
• bibcode: Bibcode; used by a number of astronomical data systems; for example: 1974AJ.....79..819H
• doi: Digital object identifier; for example: 10.1038/news070508-7. It is checked to ensure it begins with (10.).
  • doi_brokendate: Date the DOI is broken; use the same format as other dates in the article.
• isbn: International Standard Book Number; for example: 978-0-8126-9593-9. (See: Wikipedia:ISBN and ISBN). Dashes in the ISBN are optional, but preferred. Use the 13-digit ISBN wherever possible; this can normally be found beneath the barcode as a number beginning with 978 or 979 (barcodes beginning with any other numbers are not ISBNs). For sources with the older 9 digit SBN system, prefix the number with a zero; thus, SBN 902888-45-5 should be entered as |isbn=0-902888-45-5. It is checked for length, invalid characters and the proper check digit. Alias: ISBN
• issn: International Standard Serial Number; eight characters may be split into two groups of four using a hyphen, but not an en dash or a space.
• jfm: Jahrbuch über die Fortschritte der Mathematik
• jstor: JSTOR abstract; for example: "jstor=3793107" will generate JSTOR 3793107.
• lccn: Library of Congress Control Number
• mr: Mathematical Reviews
• oclc: OCLC
• ol: Open Library
• osti: Office of Scientific and Technical Information
• pmc: PubMed Central; use article number for full-text free repository of a journal article.
  • embargo: Date that pmc goes live; if this date is in the future, then pmc is not linked until that date.
• pmid: PubMed; use unique identifier.
• rfc: Request for Comments
• ssrn: Social Science Research Network
• zbl: Zentralblatt MATH

Quote

• quote: Relevant text quoted from the source. Displays enclosed in quotes.

Laysummary

• layurl: URL link to a non-technical summary or review of the source; the URL title is set to "Lay summary". Aliases: laysummary.
  • laysource: Name of the source of the laysummary. Displays in italics and preceded by an endash.
  • laydate: Date of the summary. Displays in parentheses.

Display options

• author-mask: Replaces the name of the first author with em dashes or text. Set author-mask to a numeric value n to set the dash n em spaces wide; set author-mask to a text value to display the text without a trailing author separator; for example, "with". You must still include the values for all authors for metadata purposes. Primarily intended for use with bibliography styles where multiple works by a single author are listed sequentially. Do not use in a list generated by {{reflist}}, <references />

or similar as there is no control of the order in which references are displayed.

• author-name-separator: Controls the separator between last and first names; defaults to a comma and space (, ); if the parameter is present, but blank, separator punctuation is set to the default; a space must be encoded as  .
• author-separator: Controls the separator between authors; defaults to a semicolon and space (; ); if the parameter is present, but blank, separator punctuation is set to the default; a space must be encoded as  .
• display-authors: Controls the number of author names that are displayed when a citation is published. To change the displayed number of authors, set display-authors to the desired number. For example, |display-authors=2 will display only the first two authors in a citation. By default, all authors are displayed except when there are nine authors, then the author list in the citation is truncated to eight authors, followed by "et al." This exception mimics the older version of the template for compatibility. If a citation contains nine author names and one wishes all nine author names to display, "et al." may be suppressed by setting |display-authors=9. Aliases: displayauthors.
• display-editors: Controls the number of editor names that are displayed when a citation is published. To change the displayed number of editors, set display-editors to the desired number. For example, |display-editors=2 will display only the first two editors in a citation. By default, all editors are displayed except when there are four editors, then the editor list in the citation is truncated to three editors, followed by "et al." This exception mimics the older version of the template for compatibility. If a citation contains four editor names and one wishes all four editor names to display, "et al." may be suppressed by setting |display-editors=4. Aliases: displayeditors.
• lastauthoramp: Switches the separator between the last two names of the author list to space ampersand space ( & ) when set to any value. Example: |lastauthoramp=yes
• postscript: Controls the closing punctuation for a citation; defaults to none. Ignored if quote is defined.
• separator: Controls the punctuation used to separate lists of authors, editors, etc. Defaults to a comma and space (, ); if the parameter is present, but blank, separator punctuation is set to the default; a space must be encoded as  .

Subscription or registration required

main|WP:PAYWALL These parameters add a link note to the end of the citation:

• registration: For online sources that require registration, set |registration=yes; superseded by subscription if both are set.
• subscription: For online sources that require a subscription, set |subscription=yes; supersedes registration if both are set.

United States patent with multiple inventors

{{Citation | inventor1-last = Degermark | inventor1-first = Mikael | inventor2-last = Brodnik | inventor2-first = Andrej | inventor3-last = Carlsson | inventor3-first = Svante | inventor4-last = Pink | inventor4-first = Stephen | title = Fast routing lookup system using complete prefix tree, bit vector, and pointers in a routing table for determining where to route IP datagrams | issue-date = 2001 | patent-number = 6266706 | country-code = US}}

US 6266706, Degermark, Mikael; Andrej Brodnik & Svante Carlsson et al., "Fast routing lookup system using complete prefix tree, bit vector, and pointers in a routing table for determining where to route IP datagrams", issued 2001

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 |ref=harv generates an ID suitable for Harvard referencing]] templates such as {{harv}}

as specified in the next section; this is the default for the {{citation}}

template. To disable anchor generation, specify |ref=none – leaving |ref= empty has the same effect but is ambiguous; this is the default for the Cite templates such as {{cite book}}

and {{cite news}}

. You can also specify the ID directly, using the |ref=ID parameter. For example, suppose an article's References section contains the markup:

• {{Citation |author=Sigmund Freud |title=Civilization and Its Discontents |year=1930 |ref=CivDis}}

which generates the citation:

• Sigmund Freud (1930), Civilization and Its Discontents 

Then, the markup "(#CivDis|Freud 1930)" generates a parenthetical reference "(#CivDis|Freud 193])" containing a wikilink to the citation (try clicking on the wikilink).

Anchors for Harvard referencing templates

IDs compatible with Harvard referencing templates such as {{harv}}

are computed from the last names of the authors and the year of the cited source. For example, the markup "{{harv|Wright|Evans|1851|p=ix}}" generates the Harvard reference "

", which wikilinks to the citation whose markup and appearance are shown below:

• {{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}}
• Wright, Thomas; Evans, R. H. (1851), Historical and Descriptive Account of the Caricatures of James Gillray, London: Henry G. Bohn, OCLC 59510372 

In this example the {{citation}}

template defines, and the {{harv}}

template uses, the HTML ID "CITEREFWrightEvans1851", composed by concatenating the string "CITEREF" with the last names of the authors and the year. The {{harvid}}

template can be used to generate such IDs, for example, {{harvid|Wright|Evans|1851}} generates "CITEREFWrightEvans1851".

Related methods which leave only a number in the text are to use the {{harvnb}}

template enclosed in the <ref></ref> html code, or to use the {{sfn}}

template alone. The example above would be <ref>{{harvnb|Wright|Evans|1851|p=ix}}</ref> or {{sfn|Wright|Evans|1851|p=ix}} both of which generate a footnote, such as

17. 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 |last1= (or |last=), |last2=, |last3=, and |last4=, and similarly for |editor1-last= etc. and for |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 "{{Citation | author = Sigmund Freud | title = The Ego and the Id | year = 1923}}" no last name is given, so this citation cannot be combined with the Harvard reference "{{harv|Freud|1923}}". To make these {{citation}}

and {{harv}}

invocations compatible, either replace "|author=Sigmund Freud" with "|first=Sigmund |last=Freud", or add "|ref={{harvid|Freud|1923}}" to the {{citation}}

invocation, or add the same ref parameter (say, "|ref=EgoId") to both the {{citation}}

and the {{harv}}

invocations.

Similarly, the year is used, as specified by |year=. If no year is given, this template attempts to derive the year from |date= (or, if no date is given, from |publication-date=) by applying the mw:Help:Extension:ParserFunctions##time|MediaWiki#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:MO]), but may not work as expected with other formats, so when in doubt it may be safer to use |year=. Note that if only a year, say 2005, is known you must use |year=2005 rather than |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 {{harv}}

-compatible IDs:

• Montes, G.; Halterman, J. S. (2008a), "Association of Childhood Autism Spectrum Disorders and Loss of Family Income", Pediatrics 121 (4): e821–6, doi:10.1542/peds.2007-1594, PMID 18381511, http://pediatrics.aappublications.org/cgi/content/full/121/4/e821 

• Montes, G.; Halterman, J. S. (2008b), "Child Care Problems and Employment Among Families with Preschool-aged Children with Autism in the United States", Pediatrics 122 (1): e202–8, doi:10.1542/peds.2007-3037, PMID 18595965, 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 "CITEREFMontesHalterman2008". To avoid this problem, distinguish the citations by appending suffixes to the years, e.g., "|year=2008a" and "|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.

Template Data

This template data section needs to be edited. It includes deprecated parameters and does not include parameters that were added in the Lua updates. It also includes a mix of patent and non-patent parameters.

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.
