Documentation[view] [edit] [history] [purge]


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[edit]

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).
    • 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: An 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[n 1] when the url was accessed.

Example[edit]

{{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}}
}}

Full citation parameters[edit]

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.

Parameters[edit]

Syntax[edit]

Nested parameters rely on their parent parameters:

  • parent
  • OR: parent2—may be used instead of parent
    • child—may be used with parent (and is ignored if parent is not used)
    • OR: child2—may be used instead of child (and is ignored if parent2 is not used)
Where aliases are listed, only one of the parameters may be defined; if multiple aliased parameters are defined, then only one will show.

This template embeds COinS metadata in the HTML output, allowing reference management software to retrieve bibliographic metadata. See: Wikipedia:COinS. As a general rule, only one data item per parameter. Do not include explanatory or alternate text:

  • Use |date=27 September 2007 not |date=27 September 2007 (print version 25 September)

Use of templates within the citation template, is generally discouraged as many of these templates will add a lot of extraneous HTML or CSS that will be rendered in the metadata. Also, HTML entities, for example  , –, etc, should not be used in parameters that contribute to the metadata.

COinS metadata is created for these parameters:

  • |periodical=, |journal=, |newspaper=, |magazine=, |work=, |website=, |encyclopedia=, |encyclopaedia=, |dictionary=
  • |chapter=, |contribution=, |entry=, |article=, |section=
  • |title=
  • |publicationplace=, |publication-place=
  • |date=, |year=, |publicationdate=, |publication-date=
  • |series=
  • |volume=
  • |issue=, |number=
  • |page=, |pages=, |at=
  • |edition=
  • |publisher=, |distributor=, |institution=
  • |url=
  • |chapterurl=, |chapter-url=, |contributionurl=, |contribution-url=, |sectionurl=
  • |author#=, |Author#=, |authors#=, |author#-last=, |author-last#=, |last#=, |surname#=
  • any of the identifiers (|isbn=, |issn=, |doi=, |pmc=, etc)

By default, sets of fields are terminated with a comma (,).

Deprecated[edit]

The following parameters are deprecated. Their use will place the page into Category:Pages containing cite templates with deprecated parameters:

  • access-date · accessday · accessdaymonth · accessed · accessmonth · accessmonthday · accessyear: Use accessdate to include the full date of access.
  • day: Use date to include the day, month and year.
  • dateformat · doilabel: These parameters are no longer supported.

Description[edit]

Authors[edit]

  • last: Surname of author. Do not wikilink—use authorlink instead. Where the surname is usually written first—as in Chinese—or for corporate authors, simply use last to include the same format as the source. Aliases: last1, author, authors, author1.
    • first: Given or first names of author, including title(s); for example: Firstname Middlename or Firstname M. or Dr. Firstname M., Sr. Do not wikilink—use authorlink instead. Aliases: first1. Requires last; first name will not display if last is empty.
    • OR: for multiple authors, use last1, first1 through last9, first9 for up to nine authors. By default, if nine authors are defined, then only eight will show and "et al." will show in place of the last author. See the display parameters to change. Aliases: author1 through author9.
  • authorlink: Title of existing Wikipedia article about the author—not the author's website; do not wikilink. Aliases: authorlink1, author-link, author1-link, author1link.
  • OR: for multiple authors, use authorlink1 through authorlink9. Aliases: author1-link through author9-link.
  • coauthors: (deprecated) Names of coauthors. Requires author, authors, or lastn Include coauthors in author or authors or use separate authorn or lastn/firstn to list coauthors.
  • others: To record other contributors to the work, such as Illustrated by John Smith or Translated by John Smith.
When using shortened footnotes or parenthetical referencing styles with templates, do not use multiple names in one field or else the anchor will not match the inline link.

Editors[edit]

  • editor-last: Surname of editor. Do not wikilink—use editor-link instead. Where the surname is usually written first—as in Chinese—or for corporate authors, simply use editor-last to include the same format as the source. Aliases: editor1-last, editor, editors.
    • editor-first: Given or first names of editor, including title(s); example: Firstname Middlename or Firstname M. or Dr. Firstname M., Sr. Do not wikilink—use editor-link instead. Aliases: editor1-first.
    • OR: for multiple editors, use editor1-last, editor1-first through editor4-last, editor4-first for up to four editors.
  • editor-link: Title of existing Wikipedia article about the editor—not the editor's website; do not wikilink. Aliases: editor1-link.
  • OR: for multiple editors, use editor1-link through editor4-link.
Display:
If authors: Authors are first, followed by the editors and the included work, then the main work.
If no authors: Editors appear before the included work; a single editor is followed by "ed."; multiple editors are followed by "eds."; more than three editors will be followed by "et al., eds."

Title[edit]

  • 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.
  • type: Provides additional information about the media type of the source; format in sentence case. Displays in parentheses following the title. Examples: Thesis, Booklet, CD liner, Press release.
  • 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; do not use icons or templates.

Date[edit]

  • date: Date of source being referenced. Can be full date (day, month, and year) or partial date (month and year, year). Use same format as other publication dates in the citations.[1] 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.
    • month: Name of the month or season of publication. If you also have the day, use date instead. Do not wikilink.
  • 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.
  1. ^ Publication dates in references within an article should all have the same format. See: MOS:DATEUNIFY.

Periodical[edit]

  • 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. Alias: number.
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[edit]

  • 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[edit]

  • 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[edit]

  • 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.
    • 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[edit]

  • 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. Remove spurious tracking parameters from URLs, e.g. #ixzz2rBr3aO94 or ?utm_source=google&utm_medium=...&utm_term=...&utm_campaign=.... 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; requires url.[1] 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 hidden or styled by registered editors.
    • 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 (see: Wikipedia:Using WebCite) and Internet Archive (see: Wikipedia:Using the Wayback Machine); requires archivedate and url.
      • 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. This does not necessarily have to be the same format that was used for citing publication dates.[1] Do not wikilink.
      • deadurl: When the URL is still live, but pre-emptively 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 external link icon. Note: External link icons do not include 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.
  1. ^ a b Accessdate and archivedate in references should all have the same format – either the format used for publication dates, or YYYY-MM-DD. See: MOS:DATEUNIFY.

Anchor[edit]

Identifiers[edit]

  • 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.

Quote[edit]

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

Laysummary[edit]

  • laysummary: URL link to a non-technical summary or review of the source; the URL title is set to "Lay summary".
    • 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[edit]

  • 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, no separator punctuation will be used; a space must be encoded as &#32; do not use an asterisk (*), colon (:) or hash (#) as they will be interpreted as wikimarkup.
  • author-separator: Controls the separator between authors; defaults to a semicolon and space (; ); if the parameter is present, but blank, no separator punctuation will be used; a space must be encoded as &#32; do not use an asterisk (*), colon (:) or hash (#) as they will be interpreted as wikimarkup.
  • display-authors: Controls the number of author names that are displayed when a citation is published. To control the displayed number of author names, set display-authors to the desired number. For example, |display-authors=2 will display only the first two authors in a citation. By default, the only the first eight cited authors are displayed; subsequent authors beyond eight are represented in the published citation by "et al." 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.
  • 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, no separator punctuation will be used; a space must be encoded as &#32;.

Examples[edit]

Books[edit]

Three authors, a volume, and an edition. Ampersand (&) forced before final author's name.

Anchored citations[edit]

This template can generate a citation that can be combined with shortened footnotes or parenthetical referencing. It does this by creating an 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. If an empty |ref= is given, no anchor is generated; 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 "(Freud 1930)" containing a wikilink to the citation (try clicking on the wikilink).

Anchors for Harvard referencing templates[edit]

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 "(Wright & Evans 1851, p. ix)", 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 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 MediaWiki#time function. This heuristic works with many common date formats (American, International and ISO 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 |year=. Note that if only a year, say 2005, is known you must use |year=2005 rather than |date=2005.

IDs must be unique[edit]

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:

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.

Dates[edit]

  1. ^
    • The format of dates in the references of an article should use a consistent and unambiguous style. Example formats used in Wikipedia citations include:
      • 2009
      • 2009-09-14 (ISO standard format: YYYY-MM-DD)
      • 14 September 2009
      • September 14, 2009 (with comma)
      • September 2009
    • Dates should not be linked in references.
    • Please see Wikipedia:Manual of Style (dates and numbers)#Dates for more guidance about formatting dates.
