{{csdoc}}

Usage

This template is used to build consistent documentation pages for Citation Style 1 templates.

For example: {{Citation Style documentation|author}} will show the author documentation.

Where a particular section of documentation is not appropriate for a certain template, simply add the text manually or create a new subtemplate.

Each module of text is a subtemplate that can be edited using the link.

Mysterious book.

Parameters section

syntax

[edit subtemplate]

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.

COinS

[edit subtemplate]

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  , –, etc, should not be used in parameters that contribute to the metadata. Do not include Wiki markup '' (italic font) or ''' (bold font) because these markup characters will contaminate the metadata.

COinS metadata is created for these parameters

|periodical=, |journal=, |newspaper=, |magazine=, |work=, |website=, |encyclopedia=, |encyclopaedia=, |dictionary=
|chapter=, |contribution=, |entry=, |article=, |section=
|title=
|publication-place=, |publicationplace=, |place=, |location=
|date=, |year=, |publication-date=, |publicationdate=
|series=, |version=
|volume=

|author#=, |author-last#=, |author#-last=, |last#=, |surname#=
|author-first#=, |author#-first=, |first#=, |given#=
any of the named identifiers (|isbn=, |issn=, |doi=, |pmc=, etc)

sep_period

[edit subtemplate]

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

sep_comma

[edit subtemplate]

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

required

[edit subtemplate]

This parameter is required and will generate an error if not defined. 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.

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. Alias: location

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), if the deliverer requests attribution, or as requested in WP:The Wikipedia Library (e.g. Credo, HighBeam).

Options for this field:
|work=no suppresses "; if work is defined, then publisher and location are enclosed in parentheses"

[edit subtemplate]

newsgroup: Name of newsgroup; a link is automatically created; do not wikilink.

language

[edit subtemplate]

language: The language in which the source is written. Displays in parentheses with "in" before the language name or names. Use the full language name or ISO 639-1 code. When the source uses more than one language, list them individually, separated by commas, e.g. |language=French, German. The use of language names or language codes recognized by Wikimedia adds the page to the appropriate subcategory of Category:CS1 foreign language sources; do not use templates or wikilinks. Note: When the language is "English" (or "en"), no language is displayed in the citation. Note: When two or more languages are listed there is no need to include "and" before the last language. "and" is inserted automatically by the template.

pages

[edit subtemplate]

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 <syntaxhighlight lang="text" class="" id="" style="" inline="1">p.</syntaxhighlight> 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 <syntaxhighlight lang="text" class="" id="" style="" inline="1">pp.</syntaxhighlight> unless |nopp=y. Hyphens are automatically converted to en dashes; if hyphens are appropriate, for example: pp. 3-1–3-15, use |at=.
- nopp: Set to y, yes, or true to suppress the <syntaxhighlight lang="text" class="" id="" style="" inline="1">p.</syntaxhighlight> or <syntaxhighlight lang="text" class="" id="" style="" inline="1">pp.</syntaxhighlight> 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.

- time-caption: Changes the default text displayed before time. Alias: timecaption.

id1

[edit subtemplate]

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.

id2

[edit subtemplate]

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. 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 or arxiv=1501.00001 (since April 2007). Do not include extraneous file extensions like ".pdf" or ".html".
asin: Amazon Standard Identification Number; if first character of asin value is a digit, use isbn. Because this link favours one specific distributor, only include it if standard identifiers aren't available.
- asin-tld: ASIN top-level domain for Amazon sites other than the US; valid values: au, br, ca, cn, co.jp, co.uk, de, es, fr, it, mx
bibcode: Bibcode; used by a number of astronomical data systems; for example: 1974AJ.....79..819H
biorxiv: bioRxiv id, a 6-digit number at the end of the biorXiv URL (e.g. 078733 for http://biorxiv.org/content/early/2016/10/01/078733 or https://dx.doi.org/10.1101/078733)
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 )
doi: Digital object identifier; for example: 10.1038/news070508-7. It is checked to ensure it begins with (<syntaxhighlight lang="text" class="" id="" style="" inline="1">10.</syntaxhighlight>).
- doi-broken-date: Date the DOI was found to be non-working at https://dx.doi.org. Use the same format as other dates in the article. Alias: doi_brokendate, doi-inactive-date
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. Alias: EISSN
hdl: Handle System identifier for digital objects and other resources on the Internet. Alias: HDL
isbn: International Standard Book Number; for example: 978-0-8126-9593-9. Dashes 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, prefix the number with a zero; thus, SBN 902888-45-5 should be entered as |isbn=0-902888-45-5. 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. Alias: ISBN
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. Alias: 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. Alias: ISSN
jfm: Jahrbuch über die Fortschritte der Mathematik
jstor: JSTOR reference number; for example: jstor=3793107 will generate JSTOR 3793107.
lccn: Library of Congress Control Number. When present, alphabetic prefix characters are to be lower case.
mr: Mathematical Reviews
oclc: OCLC; WorldCat's Online Computer Library Center
ol: Open Library identifier; do not include "OL" in the value.
osti: Office of Scientific and Technical Information
pmc: PubMed Central; use article number for full-text free repository of a journal article, e.g. pmc=345678. Do not include "PMC" in the value.
embargo: Date that pmc goes live; if this date is in the future, then pmc is not linked until that date.
pmid: PubMed; use unique identifier.
rfc: Request for Comments

url

[edit subtemplate]

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 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. 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 not required for links to copies of published research papers accessed via DOI or a published book, but should be used for links to news articles on commercial websites (these can change from time to time, even if they are also published in a physical medium). Note that access-date is the date that the URL was checked to not just be working, but to support the assertion being cited (which the current version of the page may not do). Can be hidden or styled by registered editors. Alias: accessdate.

archive-url: The URL of an archived copy of a web page if the original URL is no longer available. Typically used to refer to services such as WebCite and Internet Archive ; requires archive-date and url. By default (overridden by |dead-url=no) the archived link is displayed first, with the original link at the end. Alias: archiveurl.
archive-date: Date when the original URL was archived; 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. Alias: archivedate.

dead-url: the default value of this optional parameter, if omitted, is |dead-url=yes. Equivalent values are y or true. When the URL is still live, but pre-emptively archived, then set |dead-url=no; 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 |dead-url=unfit or |dead-url=usurped suppresses display of the original URL (but |url= is still required). Alias: deadurl.

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 one of the subcategories of 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. (For media format, use type.) HTML is implied and should not be specified. Automatically added 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 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: 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:

sp	"	'	<	>	[	]	{	\|	}
%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.

↑ 1.0 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.

Options for this field:

pmc adds:

" If url is not defined but pmc is, then url is set to the pmc link.

Embargo: Date that pmc goes live; if this is in the future, then url is not set to the pmc link until that date."

chapterurl

[edit subtemplate]

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.

lay

[edit subtemplate]

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

quote

[edit subtemplate]

quote: Relevant text quoted from the source. Displays enclosed in quotes. When supplied, the citation terminator (a period by default) is suppressed, so the quote must include terminating punctuation.

Options for this field:
|cs2=yes suppresses "When supplied, the citation terminator (a period by default) is suppressed, so the quote needs to include terminating punctuation."

ref

[edit subtemplate]

ref: the citation's HTML anchor identifier. When set, |ref=ID generates an anchor with the given ID (the id attribute in the citation's <cite id="ID"> HTML tag). Setting |ref=ID identifies the template as a target and allows wikilinking to full references, especially useful with short-form citations like shortened notes and parenthetical referencing. The special value |ref=harv generates an anchor identifier suitable for use with {{sfn}} and {{harv}} templates. When |mode=cs2 defaults to |ref=harv.

ref2

[edit subtemplate]

ref: the citation's HTML anchor identifier. When set, |ref=ID generates an anchor with the given ID (the id attribute in the citation's <cite id="ID"> HTML tag). Setting |ref=ID identifies the template as a target and allows wikilinking to full references, especially useful with short-form citations like shortened notes and parenthetical referencing. Defaults to the special value |ref=harv which generates an anchor identifier suitable for use with {{sfn}} and {{harv}} templates. When |mode=cs1 defaults to |ref=.

display

[edit subtemplate]

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: 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 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.
display-authors: Controls the number of author names that are displayed when a citation is published. To change the displayed number of authors, set display-authors to the desired number. For example, |display-authors=2 will display only the first two authors in a citation. By default, all authors are displayed. |display-authors=etal displays all authors in the list followed by et al. Aliases: displayauthors.
display-editors: Controls the number of editor names that are displayed when a citation is published. To change the displayed number of editors, set display-editors to the desired number. For example, |display-editors=2 will display only the first two editors in a citation. By default, all editors are displayed. |display-editors=etal displays all editors in the list followed by et al. Aliases: displayeditors.
last-author-amp: Switches the separator between the last two names of the author list to space ampersand space ( & ) when set to y, yes, or true. Example: |last-author-amp=yes
postscript: Controls the closing punctuation for a citation; defaults to a period (.); for no terminating punctuation, specify |postscript=none – leaving |postscript= empty is the same as omitting it, but is ambiguous. Ignored if quote is defined.

Options for this field:

cs2: When set, changes:
postscript to "defaults to none"

separator to "Defaults to a comma (,)"

Subscription or registration required

[edit subtemplate]

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 can signal the access restrictions of the external links included in a citation.

Four access levels can be used:

Freely accessible free: the source is free to read for anyone (this applies in particular to articles in open access)
Free registration required registration: a free registration is required to access the source
Free access subject to limited trial, subscription normally required limited: there are other constraints (such as a cap on daily views) to freely access this source
Paid subscription required subscription: the source is only accessible via a paid subscription

As there are often multiple external links with different access levels in the same citation, these values are attributed to a particular external link.

Access level of `|url=`

Links inserted with |url= are expected to be free to read by default. If not, editors can use one of

|url-access=subscription
|url-access=registration
|url-access=limited

to indicate the relevant access restriction.

Access level of identifiers

Links inserted by identifiers such as |doi= are not expected to offer a free full text by default. If they do, editors can use |doi-access=free (in the case of |doi=) to indicate the relevant access level. The following identifiers are supported:

|bibcode= with |bibcode-access=free
|doi= with |doi-access=free
|hdl= with |hdl-access=free
|jstor= with |jstor-access=free
|ol= with |ol-access=free
|osti= with |osti-access=free

Ambiguous access parameters

The parameters |registration=yes and |subscription=yes can also be used to indicate the access level of a citation. However, they do not indicate which link they apply to, so editors are encouraged to use |url-access=registration and |url-access=subscription instead, when the restriction applies to |url=. If the restriction applies to an identifier, these parameters should be omitted.

These parameters add a link note to the end of the citation:

registration: For online sources that require registration, set |registration=yes (or y, or true); superseded by subscription if both are set.
subscription: For online sources that require a subscription, set |subscription=yes (or y, or true); supersedes registration if both are set.

Setting |registration= or |subscription= to any value other than y, yes, or true will generate an error message.

map_series

[edit subtemplate]

scale: Scale of map.
series: Title of map series.
cartography: Person or entity that did the cartography, if this needs to be differentiated from general authorship of the map. Displays preceded by "Cartography by".

map_pages

[edit subtemplate]

page: Page in the source that supports the content; overridden by at.
OR: pages: Pages in the source that supports the content; separate page ranges with an en dash (–); separate non-sequential pages with a comma (,); do not use to indicate the total number of pages in the source.
inset: The name of the focused inset referenced; example: Downtown Fooburg. Output appends "inset" after the input, |inset=Downtown Fooburg becomes "Downtown Fooburg inset."; overridden by at.
section: The map section(s) of the feature referenced; example: A6, B9, L11, etc; overridden by at.
at: For sources where a single set of the above parameters is inappropriate or insufficient to describe the in-source location(s).

Examples: page (p.) or pages (pp.); inset(s); section (§) or sections (§§); other custom location on the map or in the atlas.

interview_id

[edit subtemplate]

program: News program or event.
call-sign: Radio or TV callsign. Alias: callsign.

interview_author

[edit subtemplate]

last: Surname of subject, not interviewer. Do not wikilink—use subject-link 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.
- first: Given or first names of author, including title(s); example: Firstname Middlename or Firstname M. or Dr. Firstname M., Sr.. Do not wikilink—use subject-link instead.
- OR: for multiple subjects, use first1, last1 through first9, last9 for up to nine subjects. By default, if nine subjects are defined, then only eight will show and "et al." will show in place of the last author.

subject-link: Title of existing Wikipedia article about the subject—not the subject's website; do not wikilink.
OR: for multiple subjects, use subject-link1 through subject-link9.

Aliases: subject, last, last1, author1, author, authors; subject2, last2, author2 through subject9, last9, author9; subjectlink, authorlink, authorlink1; subjectlink2, authorlink2 through subjectlink9, authorlink9.

[edit subtemplate]

season: Season number, usually for US shows.
OR: series-number: Series number, usually for British shows. Aliases: series-no, seriesno, seriesnumber.
number: Many episodic shows are identified by separate season and episode numbers. Alternately, some shows prefer the format of a single episode number that includes the season within it; this format can be used by omitting the season field.
