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
golegiThis 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.
- publication-place (or place): 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.
- 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

Full citation parameters
golegiThese 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.

- author-mask: See #Additional parameters, below.
- display-authors: Truncate the list of authors at an arbitrary point with "et al". You should still include the first 9 authors to allow metadata to be generated. n.b. operates only when the authors are given using either several
|authorn=
, or several|lastn=
|firstn=
pairs; does not affect the display of a list in either|authors=
or|coauthors=
. - lastauthoramp: If supplied, whether or not assigned a value, places an ampersand (&) before the last name of final author, if more than one author is supplied. Recommended usage is lastauthoramp = yes.
- coauthors: Names of additional author(s) can be given but author2 or last2, first2 is preferred.

- month: Month of publication (ignored if the date field is used).
- origyear: Year of first publication, if different.
- title: Title of the book or article in a periodical. If the title includes [square brackets], these must be encoded as "

" for "]" - chapter or contribution: title of the chapter or part of a publication will be put in quotes.
- chapter-url or contribution-url: use to add a link to the chapter or contribution title.
- type: An optional field which can be used to provide additional information about a publication type. The content appears in parentheses following the title. If the publication is a thesis or dissertation, the type might be specified as
type = PhD thesis
, If the publication is an audiobook on compact disk, the type might be specified astype = CD
.- journal or periodical or newspaper or magazine or work: Name of the journal or periodical.
- edition: Number or name of the edition, if not the first; for example: edition = 2nd.
- series: The book series of which this book is a part.
- volume: The volume number of a multi-volume book.
- issue: Issue number of a periodical.
- publisher: The name of the publisher. Omit terms such as Publishers, Co., Inc., Ltd., etc., but retain the words Books or Press. Not needed if ISSN or DOI used.
- publication-place (or place): 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. If the city is not well-known, you may add a county, region, or state. States in the U.S. are denoted by a two-letter code; for example:
place = Paris, TX
(no period at the end). Where the publisher is a university and the place or location is included in the name of the university, do not use this parameter.- place or location: City in which the work was made, if different from the city of publication. If only place is used, it will be treated as the city of publication.
- publication-place (or place): 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. If the city is not well-known, you may add a county, region, or state. States in the U.S. are denoted by a two-letter code; for example:
- language: If not English. e.g., Finnish.
- page: For use when one page is cited. Adds "p." before the page number. Do not use with pages.
- pages: For use when multiple pages are cited. Adds "pp." before the page numbers. Do not use with page.
- nopp: if set to any value,
page = /pages =
do not generate 'p.' or 'pp.'. E.g.nopp = true
. Usingat =
has the same effect. - at: Position within the resource when
|page=
/|pages=
is inappropriate or insufficient. This parameter is ignored if|page=
/|pages=
is specified. Examples of usage of|at=
:|at=para. 14
(when citing a source without page numbers),|at=02:56
(a film or audio timestamp),|at=no. 456
(something in a numbered list),|at=p. 6, col. 2
(for a page and a column because "column" is not a Citation template parameter), or|at=sec. F pp. 4–6
(for a section and a page within the section, "section" not being a parameter).

- isbn: International Standard Book Number such as 978-0812695939; see Wikipedia:ISBN and ISBN. Dashes in the ISBN are optional, but preferred. Use the 13-digit ISBN where possible; this can normally be found beneath the barcode as a number beginning 978 or 979. For sources with the older 9 digit SBN system, prefix the number with a zero; thus SBN 812695-93-3 should be entered as
|isbn=0812695-93-3

- accessdate: Full date when URL was accessed; use the same format as other access and archive dates in the citations;[1] do not wikilink. Can be hidden 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 and the Internet Archive; requires archivedate.
- archivedate: Date when the item was archived; use the same format as other access and archive dates in the citations;[1] do not wikilink. Displays preceded by "archived from the original on".
- 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 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. Does not change external link icon.

IPv6 host-names are currently not supported. - If URLs in citation template parameters contain certain characters they will display and link incorrectly. Those characters need to be percent-encoded. For example, a space must be replaced by
%20
. To encode the URL, replace these characters:

---|---|---|---|---|---|---|---|---|
%20 | %22 | %27 | %3c | %3e | %5b | %5d | %7c | %7d |
- Single apostrophes do not need to be encoded; but unencoded multiples will be parsed as italic or bold markup. Single curly closing braces also do not need to be encoded; but an unencoded pair will be parsed as the double closing braces for the template transclusion.
- separator: specifies the punctuation mark used to separate certain fields. This defaults to a comma; the Citation Style 1 family of templates uses a period.
- laysummary: url of a lay summary of a technical article, which could be in a popular science magazine or newspaper.
- laysource: Name of the source, e.g., The Guardian (UK newspaper) or New Scientist.
- laydate: The date[n 1] of publication or, where this is not available, date of retrieval of the lay summary.
- postscript: Set terminal punctuation. Omit or leave blank to remove the trailing full stop. Punctuation specified by this parameter will appear within the cite span, and consequently before any icons added by metadata-using software, e.g., library browser plugins. Hence this parameter should be used instead of manually appending data to the citation. This parameter is ignored if
|quote=
is specified, when|postscript=.

Anchored citations
golegiThis 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
golegiIDs 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, t. 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
golegiNames, 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, JS (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, JS (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.
Dates
golegi- ↑ 1.0 1.1 1.2 1.3
- 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)
- 2009 Sep 14
- September 2009
- Sept./Oct. 2009
- As indicated above, month names are sometimes abbreviated, e.g., September to "Sept" or "Sept." or "Sep" or "Sep."
- Dates should not be linked in references.
- Please see Wikipedia:Manual of Style (dates and numbers)#Dates for more guidance about formatting dates.

TemplateData
golegiThe 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.
Parameter | Description | Type | Status | |
---|---|---|---|---|
Last name | last author author1 authors last1 | The surname of the author; don't wikilink, use 'authorlink'; can suffix with a numeral to add additional authors | Line | suggested |
First name | first first1 | Given or first name, middle names, or initials of the author; don't wikilink, use 'authorlink'; can suffix with a numeral to add additional authors | Line | suggested |
title of source | title | Title of source; displays in italics. | String | required |
date of source | date | Full date of source being referenced in the same format as other publication dates in the citations.[1] Do not wikilink. Displays after the authors and enclosed in parentheses. If there is no author, then displays after publisher. | String | optional |

You must still include the values for all authors for metadata purposes. Primarily intended for use with bibliographies or bibliography styles where multiple works by a single author are listed sequentially such as shortened footnotes. 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. You can also use editor-mask and translator-mask in the same way. | String | optional |

COinS
golegiThis template produces COinS metadata; see COinS in Wikipedia for background information.
Additional parameters
golegiauthor-mask — This parameter is primarily intended for use in bibliographies where multiple works by a single author are listed; it is not for use in in-text citations, as it presents the same problems as the use of ibid (see WP:IBID). It replaces the name of the first author (which must still be provided to garner metadata) with a strike-through dash (—) author-mask em in length. So, if |author-mask=1
then the dash will be one em in length, if |author-mask=2
it will be two em long, and so on. Set author-mask to a text value to display a word instead – for example, "with". You must still include |last=
and |first=
for metadata purposes.
