Template 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. As with other citation templates, this template can be used either in a footnote (between <ref>...</ref> tags) or in a section that lists sources. This template uses the same Lua code as citation style 1 (CS1) templates with parameters to change the displayed format to citation style 2 (CS2).

If the correct parameters are used, this template produces output identical to that of the Cite templates, such as {{Cite book}} and {{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 references 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.

Simple citations[edit]

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.

{{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 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 |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: A 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
| ol        = 7120924W
}}
Turner, Orsamus (1851), History of the pioneer settlement of Phelps and Gorham's purchase, and Morris' reserve, Rochester, New York: William Alling, 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.

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

COinS[edit]

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 discouraged because many of these templates will add extraneous HTML or CSS that will be included raw in the metadata. Also, HTML entities, for example &nbsp;, &ndash;, etc., should not be used in parameters that contribute to the metadata.

COinS metadata is created for these parameters[edit]

Note: This table of metadata is displayed for all Citation Style 1 templates. Not all of these parameters are supported by every CS1 template. Some of these parameters are mutually exclusive, some are aliases of another parameter, and some require other parameters to be present. Please refer to each template's documentation for a full list of supported parameters, their aliases, and their dependencies.

    |vauthors=Smythe JB, ((Megabux Corp.)), etal
    • author-link and author-mask may be used for the individual names in |vauthors= as described above
  • authors: Free-form list of author names; use of this parameter is discouraged because it does not contribute to a citation's metadata; not an alias of last.
  • contributor-last: (book cites only) surname of the author of contribution (which is required). Aliases: contributor-surname, contributor1, contributor1-last, contributor-last1.
    • contributor-first: Given or first names of contributor. Do not wikilink—use contributor-link instead. Aliases: contributor-given, contributor1-first, contributor-first1.

    • translator-link: Title of existing Wikipedia article about the translator—not the translator's website; do not wikilink. Aliases: translator-link1, translator1-link.
    • OR: for multiple translators, use translator-link1 through translator-linkn. Aliases: translator1-link through translatorn-link.
  • collaboration: Name of a group of authors or collaborators; requires author, last, or vauthors listing one or more primary authors; follows author name-list; appends "et al." to author name-list.
  • others: To record other contributors to the work, including illustrators. For the parameter value, write Illustrated by John Smith.
  • Note: 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: editor-last1, editor1-last, editor-surname, editor-surname1, editor1-surname, editor, editor1.
    • editor: This parameter is used to hold the complete name of a single editor (first and last), or the name of an editorial committee. This parameter should never hold the names of more than one editor.

  • veditors: comma separated list of editor names in Vancouver style; enclose corporate or institutional names in doubled parentheses. End with etal if appropriate:
    |veditors=Smythe JB, ((Megabux Corp.)), etal
    • editor-linkn and editor-maskn may be used for the individual names in |veditors=, as described above
  • Display:
    Use display-editors to control the length of the displayed editor name list and to specify when "et al." is included.
    If authors: Authors are first, followed by the included work, then "In" and the editors, 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."

Title[edit]

(See also Help:Citation Style 1 § Titles and chapters.)

  • 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. If script-title is defined, use title to hold a Romanization (if available) of the title in script-title.
    • script-title: Original title for languages that do not use a Latin-based script (Arabic, Chinese, Cyrillic, Greek, Hebrew, Japanese, Korean, etc.); not italicized, follows italicized Romanization defined in title (if present). Must be prefixed with one of the supported language codes to help browsers properly display the script:
      ... |title=Tōkyō tawā |script-title=ja:東京タワー |trans-title=Tokyo Tower ...
    • 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 not display and link correctly unless those characters are encoded.
newline [ ] |
space &#91; &#93; {{!}} (preferred)
{{bracket|text}} &#124; or {{pipe}}see also Help:Table § Rendering the pipe
  • title-link: Title of existing Wikipedia article about the source named in title – do not use a web address; do not wikilink.
  • chapter: The chapter heading of the source. May be wikilinked or may use chapter-url, but not both. Displays in quotes.
    • script-chapter: Chapter heading for languages that do not use a Latin-based alphabet (Arabic, Chinese, Cyrillic, Greek, Hebrew, Japanese, Korean, Vietnamese, etc); follows transliteration defined in chapter. Should be prefixed with an ISO 639-1 two-character code to help browsers properly display the script:
      ... |chapter=Tōkyō tawā |script-chapter=ja:東京タワー |trans-chapter=Tokyo Tower ...
    • 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. May alternatively be used to identify the type of manuscript linked to in the title, if this is not the final version of a manuscript (e.g. if a preprint of a manuscript is freely available, but the version of record is behind a paywall). Format in sentence case. Displays in parentheses following the title. The reserved keyword none can be used to disable the display of a type. Examples: Thesis, Booklet, Accepted manuscript, CD liner, Press release. Alias: medium.
  • language: The language (or a comma-separated list of the languages) in which the source is written, as either the ISO 639 language code (preferred) or the full language name. Examples: |language=ru; |lang=fr, pt-br; |lang=Russian; |language=French, Portuguese. See the list of supported codes and names. Do not use templates or wikilinks. Displays in parentheses with "in" before the language name or names. When the only source language is English, no language is displayed in the citation. The use of languages recognized by the citation module adds the page to the appropriate subcategory of Category:CS1 foreign language sources. Because cs1|2 templates are often copied from en.wiki to other wikis, the use of language codes is preferred so that language names render in the correct language and form: español at a French-language wiki instead of the English word "Spanish". Aliases: lang

Date[edit]

  • date: Date of referenced source. Can be full date (day, month, and year) or partial date (month and year, season and year, or year). Use same format as other publication dates in the citations.[date 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 the publisher. For acceptable date formats, see Help:Citation Style 1 § Dates.
For approximate year, precede with "c. ", like this: |date=c. 1900.

For no date, or "undated", use |date=n.d.
Automatic date formatting: Citation Style 1 and 2 templates, including this template, automatically render dates in all date parameters (such as |date=, |publication-date=, |access-date=, |archive-date=, etc.) except for |orig-date= in the style specified by the article's {{use dmy dates}} or {{use mdy dates}} template. See those templates' documentation for details.
  • year: Year of source being referenced. The usage of this parameter is discouraged; use the more flexible |date= parameter instead unless both of the following conditions are met:
    1. The |date= format is YYYY-MM-DD.
    2. The citation requires a CITEREF disambiguator.
  • orig-date: Original publication date or year; displays in square brackets after the date (or year). For clarity, please supply specifics. For example: |orig-date=First published 1859 or |orig-date=Composed 1904. As |orig-date= does not support automatic date formatting, use the same date format as defined by |df= (or, if it exists in the article, by |cs1-dates= of a {{use dmy dates}} or {{use mdy dates}} template), or as used in the |date= parameter. Alias: orig-year
  • df: date format; sets rendered dates to the specified format; does not support date ranges or seasonal dates; overrides the automatic date formatting described above. Accepts one value which may be one of these:
    dmy – set publication dates to day month year format; access- and archive-dates are not modified;
    mdy – as above for month day, year format
    ymd – as above for year initial numeric format YYYY-MM-DD
    dmy-all – set publication, access-, and archive-dates to day month year format;
    mdy-all – as above for month day, year format
    ymd-all – as above for year initial numeric format YYYY-MM-DD
  1. Publication dates in references within an article should all have the same format. This may be a different format from that used for archive and access dates. See MOS:DATEUNIFY.

Periodical[edit]

  • work (required by {{cite journal}} and {{cite magazine}}): Name of the work containing the source; may be wikilinked if relevant. Displays in italics. If the name of the periodical changed over time use the name at the time of the source's publication. If script-work is defined, use work to hold a Romanization (if available) of the title in script-work Aliases: journal, newspaper, magazine, periodical, website. Use Latin script. For languages written in non-Latin based scripts (Arabic, Chinese, Cyrillic, Greek, Hebrew, Indic, Japanese, Korean, etc.) use a standard Romanization in this field.
    • script-work: Work title in its original, non-Latin script; not italicized, follows italicized Romanization defined in work (if present). Must be prefixed with one of the supported language codes to help browsers properly display the script. Leave empty for Latin-based scripts (Czech, French, Turkish, Vietnamese, etc.). Aliases: script-journal, script-newspaper, script-magazine, script-periodical, script-website.
    • trans-work: English translation of the work title if the source cited is in a foreign language. Displays in square brackets after work or script-work. Aliases: trans-journal, trans-newspaper, trans-magazine, trans-periodical, trans-website.
      ... |work=Zhōngguó piàofáng |script-work=zh:中国票房 |trans-work=China Box Office ...
    • issue: When the publication is one of a series that is published periodically. Alias: number. When the issue has a special title of its own, this may be given, in italics, along with the issue number, e.g. |issue=2, ''Modern Canadian Literature''. Please choose either |issue= or |number= depending on what is used in the actual publication. If a publication carries both, issue and number designations (typically one being a year-relative and the other an absolute value), provide them both, for example |issue=2 #143. Displayed in parentheses following volume.
When set, work changes the formatting of other parameters in the same citation:
title is not italicized and is enclosed in quotes.
chapter does not display (and will produce an error message).

Publisher[edit]

  • publisher: Name of publisher; may be wikilinked if relevant. The publisher is the company, organization or other legal entity that publishes the work being cited. Do not use the publisher parameter for the name of a work (e.g. a website, book, encyclopedia, newspaper, magazine, journal, etc.). If the name of the publisher changed over time use the name as stated in the publication or at the time of the source's publication. Corporate designations such as "Ltd", "Inc.", or "GmbH" are not usually included. Not normally used for periodicals. 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.
  • place: For news stories with a dateline, that is, the location where the story was written. If the name of the location changed over time use the name as stated in the publication or at the time of the source's publication. In earlier versions of the template this was the publication place, and for compatibility, will be treated as the publication place if the publication-place parameter is absent; see that parameter for further information. Alias: location
  • publication-place: Geographical place of publication; generally not wikilinked; omit when the name of the work includes the publication place; examples: The Boston Globe, The Times of India. Displays after the title. If the name of the publication place changed over time use the name as stated in the publication or at the time of the source's publication. If only one of publication-place, place, or location is defined, it will be treated as the publication place and will show after the title; if publication-place and place or location are defined, then place or location is 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 date (or year) 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.
  • via: Name of the content deliverer (if different from publisher). via is not a replacement for publisher, but provides additional detail. It may be used when the content deliverer presents the source in a format other than the original (e.g. NewsBank), when the URL provided does not make clear the identity of the deliverer, where no URL or DOI is available (EBSCO), or if the deliverer requests attribution. See the access level parameters to display access restrictions.

Edition, series, volume[edit]

  • edition: When the publication has more than one edition; for example: "2nd", "Revised", and so forth. Appends the string " ed." after the 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; volume numbers should be entered just as a numeral (e.g. 37); volume values that are wholly digits, wholly uppercase Roman numerals, or less than five characters will appear in bold. Any non-numeric value of five or more characters will be presumed to follow some other convention and will not appear in bold. In rare cases publications carry both, an ongoing volume and a year-related value; if so, provide them both, for example |volume=IV / #10.

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 |no-pp=yes. If hyphenated, use {{hyphen}} to indicate this is intentional (e.g. |page=3{{hyphen}}12), otherwise several editors and semi-automated tools will assume this was a misuse of the parameter to indicate a page range and will convert |page=3-12 to |pages=3{{ndash}}12. Alias: p.
  • 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 |no-pp=yes.
    Hyphens are automatically converted to en dashes; if hyphens are appropriate because individual page numbers contain hyphens, for example: pp. 3-1–3-15, use double parentheses to tell the template to display the value of |pages= without processing it, and use {{hyphen}} to indicate to editors that a hyphen is really intended: |pages=((3{{hyphen}}1{{ndash}}3{{hyphen}}15)). Alternatively, use |at=, like this: |at=pp. 3-1&ndash;3-15. Alias: pp.
    • no-pp: Set to yes, y, or true to suppress the p. or pp. notations where this is inappropriate; for example, where |page=Front cover or |pages=passim.
  • 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.
  • For |quote-page= and |quote-pages= used in conjunction with |quote=, see here.

URL[edit]

  • 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. #ixzz2rBr3aO94 or ?utm_source=google&utm_medium=...&utm_term=...&utm_campaign=.... For linking to pages in PDF files or in Google Books, see WP:PAGELINKS. Do not link to any commercial booksellers, such as Amazon; use |isbn= or |oclc= 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.[date 1] 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 {{use dmy dates}} and {{use mdy dates}}. 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 (see Wikipedia:Using the Wayback Machine), WebCite (see Wikipedia:Using WebCite) and archive.is (see Wikipedia:Using archive.is); requires archive-date and url. By default (overridden by |url-status=live) 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.[date 1] Do not wikilink; templated dates are discouraged. See "Automatic date formatting" above for details about interaction with {{use dmy dates}} and {{use mdy dates}}. 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 |url-status=dead. When the URL is still live, but pre-emptively archived, then set |url-status=live; 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 |url-status=unfit or |url-status=usurped suppresses display of the original URL (but |url= and |archive-url= are still required).
      • archive-format: File format of the work referred to by archive-url; for example: PDF, DOC, or XLS; displayed in parentheses after the archive link. HTML is implied and should not be specified. File format annotation is automatically rendered 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 file format information for the visually impaired. See Using |format=
    • url-access: See Access indicators for url-holding parameters
  • format: File 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. File format annotation is automatically rendered 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 file format information for the visually impaired. See Using |format=

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: may 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:

Character space " ' < > [ ] { | }
Encoding %20 %22 %27 %3C %3E %5B %5D %7B %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. 1.0 1.1 Access-date and archive-date in references should all have the same format – either the format used for publication dates, or YYYY-MM-DD. See MOS:DATEUNIFY.

Chapter URL[edit]

  • chapter-url: URL of an individual chapter of online source. Should be at the same site as url, if any. If chapter-url is used, url should only be used if the beginning of the work and the cited chapter are on separate webpages at the site. chapter may be wikilinked or chapter-url used, but not both. Aliases: chapterurl, contribution-url, section-url.
  • chapter-format: Format of the work referred to by chapter-url; for example: PDF, DOC, or XLS; displayed in parentheses after chapter. 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.

Anchor[edit]

Identifiers[edit]

  • id: A unique identifier, used where none of the specialized identifiers are applicable; wikilink or use a template as applicable. For example, |id=NCJ 122967 will append "NCJ 122967" at the end of the citation. You can use templates such as |id={{NCJ|122967}} to append NCJ 122967 instead.

The following 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. In general, the parameters should include only the variable part of the identifier, e.g. |rfc=822 or |pmc=345678.

  • arxiv: arXiv identifier; for example: |arxiv=hep-th/9205027 (before April 2007) or |arxiv=0706.0001 (April 2007 – December 2014) or |arxiv=1501.00001 (since January 2015). Do not include extraneous file extensions like ".pdf" or ".html". Aliases: eprint.
  • asin: Amazon Standard Identification Number; if first character of asin value is a digit, use isbn. Because this link favours one specific distributor, include it only if standard identifiers are not available. Example |asin=B00005N5PF. Aliases: ASIN.
    • asin-tld: ASIN top-level domain for Amazon sites other than the US; valid values: {{#lst:Help:CS1 errors|asin-tld_values_list}}. Aliases: none.
  • bibcode: bibcode; used by a number of astronomical data systems; for example: 1974AJ.....79..819H. Aliases: none.
  • biorxiv: bioRxiv id, as in the entire DOI (e.g. 10.1101/078733 for http://biorxiv.org/content/early/2016/10/01/078733 or https://doi.org/10.1101/078733; 10.1101/2020.07.24.220400 for https://doi.org/10.1101/2020.07.24.220400). Aliases: none.
  • citeseerx: CiteSeerX id, a string of digits and dots found in a CiteSeerX URL (e.g. 10.1.1.176.341 for http://citeseerx.ist.psu.edu/viewdoc/summary?doi=10.1.1.176.341). Aliases: none.
  • doi: Digital object identifier; for example: 10.1038/news070508-7. It is checked to ensure it begins with (10.). Aliases: DOI.
    • Supports accept-this-as-written markup to indicate valid DOIs using a non-standard format, see below.
    • doi-broken-date: Date a valid DOI was found to be non-working/inactive at https://doi.org. Use the same format as other dates in the article. Aliases: none.
  • eissn: International Standard Serial Number for the electronic media of a serial publication; eight characters may be split into two groups of four using a hyphen, but not an en dash or a space; example |eissn=1557-2986. Aliases: EISSN.
    • Supports accept-this-as-written markup to indicate valid eISSNs using a non-standard format, see below.
  • hdl: Handle System identifier for digital objects and other resources on the Internet; example |hdl=20.1000/100. Aliases: HDL.
  • isbn: International Standard Book Number; for example: 978-0-8126-9593-9. (See Wikipedia:ISBN and ISBN § Overview.) Hyphens in the ISBN are optional, but preferred. Use the ISBN actually printed on or in the book. Use the 13-digit ISBN – beginning with 978 or 979 – when it is available. If only a 10-digit ISBN is printed on or in the book, use it. ISBNs can be found on the page with the publisher's information – usually the back of the title page – or 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, use sbn. Do not convert a 10-digit ISBN to 13-digit by just adding the 978 prefix; the last digit is a calculated check digit and just making changes to the numbers will make the ISBN invalid. This parameter should hold only the ISBN without any additional characters. It is checked for length, invalid characters – anything other than numbers, spaces, and hyphens, with "X" permitted as the last character in a 10-digit ISBN – and the proper check digit. Aliases: ISBN, isbn13, ISBN13.
    • Supports accept-this-as-written markup to indicate valid ISBNs using a non-standard format, see below.
  • ismn: International Standard Music Number; for example: 979-0-9016791-7-7. Hyphens or spaces in the ISMN are optional. Use the ISMN actually printed on or in the work. This parameter should hold only the ISMN without any additional characters. It is checked for length, invalid characters – anything other than numbers, spaces, and hyphens – and the proper check digit. Aliases: ISMN.
  • 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; example |issn=2049-3630. Aliases: ISSN.
    • Supports accept-this-as-written markup to indicate valid ISSNs using a non-standard format, see below.
  • jfm: Jahrbuch über die Fortschritte der Mathematik; do not include "JFM" in the value; example |jfm=53.0144.01. Aliases: JFM.
  • jstor: JSTOR reference number; for example: |jstor=3793107. Aliases: JSTOR.
  • lccn: Library of Congress Control Number. When present, alphabetic prefix characters are to be lower case and without a space; example |lccn=79-57364 or |lccn=2004042477 or |lccn=e09001178. Aliases: LCCN.
  • mr: Mathematical Reviews; example |mr=630583. Aliases: MR.
  • oclc: OCLC Number for looking up publications in the WorldCat union catalog; example |oclc=9355469. Aliases: OCLC.
  • ol: Open Library identifier; do not include "OL" in the value; example |ol=7030731M. Aliases: OL.
  • osti: Office of Scientific and Technical Information; example |osti=4367507. Aliases: OSTI.
  • pmc: PubMed Central; use article number for open repository full-text of a journal article, e.g. |pmc=345678. Do not include "PMC" in the value. See also the pmid parameter, below; these are two different identifiers.. Aliases: PMC.
    • pmc-embargo-date: Date that pmc goes live; if this date is in the future, then pmc is not linked until that date. Aliases: none.
  • pmid: PubMed; use unique identifier; example |pmid=17322060 See also the pmc parameter, above; these are two different identifiers. Aliases: PMID.
  • rfc: Request for Comments; example |rfc=3143. Aliases: RFC.
  • sbn: Standard Book Number; example |sbn=356-02201-3. Aliases: SBN.
    • Supports accept-this-as-written markup to indicate valid SBNs using a non-standard format, see below.
  • ssrn: Social Science Research Network; example |ssrn=1900856. Aliases: SSRN.
  • s2cid: Semantic Scholar corpus ID; example |s2cid=37220927. Aliases: S2CID.
  • zbl: Zentralblatt MATH; example |zbl=0472.53010 For zbMATH search results like JFM 35.0387.02 use |jfm=35.0387.02. Aliases: ZBL.

In very rare cases, valid identifiers (f.e., as actually printed on publications) do not follow their defined standard format or use non-conforming checksums, which would typically cause an error message to be shown. Do not alter them to match a different checksum. In order to suppress the error message, some identifiers (|doi=, |eissn=, |isbn=, |issn=, and |sbn=) support a special accept-this-as-written markup which can be applied to disable the error-checking (as |<param>=((<value>))). If the problem is down to a mere typographical error in a third-party source, correct the identifier value instead of overriding the error message.

For some identifiers, it is possible to specify the access status using the corresponding |<param>-access= parameter.

For {{cite journal}}, some identifiers (specifying free resources) will automatically be linked to the title when |url= and |title-link= are not used to specify a different link target. This behaviour can be overridden by one out of a number of special keywords for |title-link= to manually select a specific source (|title-link=pmc or |title-link=doi) for auto-linking or to disable the feature (|title-link=none).

It is not necessary to specify a URL to a link identical to a link also produced by an identifier. The |url= parameter (or |title-link=) can then be used for providing a direct deep link to the corresponding document or a convenience link to a resource that would not otherwise be obviously accessible.

Quote[edit]

  • quote: Relevant text quoted from the source. Displays enclosed in quotes. If script-quote is defined, use quote to hold a Romanization (if available) of the text in script-quote.
    • script-quote: Original quotation for languages that do not use a Latin-based script (Arabic, Chinese, Cyrillic, Greek, Hebrew, Japanese, Korean, etc.); not italicized, follows italicized Romanization defined in quote (if available). Alias: none. Must be prefixed with one of the supported language codes to help browsers properly display the script:
      ... |quote=Tōkyō tawā |script-quote=ja:東京タワー |trans-quote=Tokyo Tower ...
    • trans-quote: English translation of the quotation if the source quoted is in a foreign language. Displays in square brackets. Alias: none.
  • quote-page: The number of a single page quoted in |quote=. Use either |quote-page= or |quote-pages=, but not both. Should be a subset of the page(s) specified in |page=, |pages= or |at=. Displays preceded by p. unless |no-pp=yes. If hyphenated, use {{hyphen}} to indicate this is intentional (e.g. |quote-page=3{{hyphen}}12). Alias: none.
  • OR: quote-pages: A list or range of pages quoted in |quote=. Use either |quote-page= or |quote-pages=, but not both. Should be a subset of the pages specified in |pages= or |at=. Separate using an en dash (–); separate non-sequential pages with a comma (,). Displays preceded by pp. unless |no-pp=yes is defined. Hyphens are automatically converted to en dashes; if hyphens are appropriate because individual page numbers contain hyphens, for example: pp. 3-1–3-15, use double parentheses to tell the template to display the value of |quote-pages= without processing it, and use {{hyphen}} to indicate to editors that a hyphen is really intended: |quote-pages=((3{{hyphen}}1{{ndash}}3{{hyphen}}15)). Alias: none.

Laysummary[edit]

  • lay-url: URL link to a non-technical summary or review of the source; the URL title is set to "Lay summary".
    • lay-source: Name of the source of the lay summary. Displays in italics and preceded by a spaced endash.
    • lay-date: Date of the lay summary. Displays in parentheses.
    • lay-format: File format of the work referred to by lay-url; for example: PDF, DOC, or XLS; displayed in parentheses after lay summary. HTML is implied and should not be specified. File format annotation is automatically rendered 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 file format information for the visually impaired. See Using |format=

Display options[edit]

  • mode: Sets element separator, default terminal punctuation, and certain capitalization according to the value provided. For |mode=cs1, element separator and terminal punctuation is a period (.); where appropriate, initial letters of certain words are capitalized ('Retrieved...'). For |mode=cs2, element separator is a comma (,); terminal punctuation is omitted; where appropriate, initial letters of certain words are not capitalized ('retrieved...'). To override default terminal punctuation use postscript.
  • author-mask:
  • contributor-mask:
  • editor-mask:
  • interviewer-mask:
  • subject-mask:
  • translator-mask:
    Replaces the name of the (first) author with em dashes or text. Set <name>-mask to a numeric value n to set the dash n em spaces wide; set <name>-mask to a text value to display the text without a trailing author separator; for example, "with". The numeric value 0 is a special case to be used in conjunction with <name>-link—in this case, the value of <name>-link will be used as (linked) text. In either case, you must still include the values for all names 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. Mask parameters can take an enumerator in the name of the parameter (e.g. |authorn-mask=) to apply the mask to a specific name.
  • display-authors:
  • display-contributors:
  • display-editors:
  • display-interviewers:
  • display-subjects:
  • display-translators:
    Controls the number of author or editor names that are displayed when a citation is published. To change the displayed number of names, set display-authors and/or display-editors to the desired number. For example, |display-authors=2 will display only the first two authors in a citation (and not affect the display of editors). Likewise, |display-editors=2 will display only the first two editors (and all authors). |display-authors=0 and |display-editors=0 are special cases suppressing the display of all authors or editors including the et al. By default, all authors and editors are displayed. |display-authors=etal displays all authors in the list followed by et al. Aliases: none.
  • postscript: Controls the closing punctuation for a citation; defaults to none. Additional text or templates beyond the terminating punctuation may generate an error message. |postscript= is ignored if quote is defined.

Subscription or registration required[edit]

Citations of online sources that require registration or a subscription are acceptable in Wikipedia as documented in Verifiability § Access to sources. As a courtesy to readers and other editors, editors should signal restrictions on access to material provided via the external links included in a citation. These levels describe requirements or constraints related to accessing and viewing the cited material; they are not intended to indicate the ability to reuse, or the copyright status, of the material, since that status is not relevant to verifying claims in articles.

Four access levels can be used:

As there are often multiple external links with different access levels in the same citation, each value is attributed to a specific external link.

Access indicators for url-holding parameters[edit]

Online sources linked by |url=, |article-url=, |chapter-url=, |contribution-url=, |entry-url=, |map-url=, and |section-url= are presumed to be free-to-read.[1] When they are not free-to-read, editors should mark those sources with the matching access-indicator parameter so that an appropriate icon is included in the rendered citation. Because the sources linked by these url-holding parameters are presumed to be free-to-read, they may not be marked as free.

URL-holding and access-indicator parameters
URL Access Allowed keywords
|url= |url-access= registration Free registration required
limited Free access subject to limited trial, subscription normally required
subscription Paid subscription required
|article-url= |article-url-access=
|chapter-url= |chapter-url-access=
|contribution-url= |contribution-url-access=
|entry-url= |entry-url-access=
|map-url= |map-url-access=
|section-url= |section-url-access=
  1. This guidance does not restrict linking to websites that are being used as sources to provide content in articles.

For example, this cites a web page that requires registration but not subscription:

{{cite web |url=https://example.com/nifty_data.php |url-access=registration |date=2021-04-15 |title=Nifty example data}}

which renders as:

"Nifty example data". 2021-04-15.
Access indicator for named identifiers[edit]

Links inserted by named identifiers are presumed to lie behind a paywall or registration barrier – exceptions listed below. When they are free-to-read, editors should mark those sources with the matching access-indicator parameter so that an appropriate icon is included in the rendered citation. When the sources linked by these named-identifier parameters are not presumed to carry a free-to-read full text (for instance because they're just abstracting services), they may not be marked as limited, registration, or subscription.

Named-identifier and access-indicator parameters
Identifier Access Allowed keywords
|bibcode= |bibcode-access= free Freely accessible
|doi= |doi-access=
|hdl= |hdl-access=
|jstor= |jstor-access=
|ol= |ol-access=
|osti= |osti-access=
|s2cid= |s2cid-access=

Some named-identifiers are always free-to-read. For those named identifiers there are no access-indicator parameters; the access level is automatically indicated by the template. These named identifiers are:

  • |arxiv=
  • |biorxiv=
  • |citeseerx=
  • |pmc=
  • |rfc=
  • |ssrn=

For embargoed pmc that will become available in the future, see pmc-embargo-date.

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.

To disable anchor generation, specify |ref=none (in contrast, other Cite templates such as {{cite book}} and {{cite news}} do not create an anchor by default). 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 (or editors, if no authors are given) 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 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 |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 consistent and unambiguous styles. Example formats used in Wikipedia citations include: 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 for more guidance about formatting dates.

Tools[edit]

See Wikipedia:Citing sources § Citation templates and tools for a list of tools that can help create a reference in the "citation" format.
