This Citation Style 1 template is used to create citations for preprints at arXiv. It links to the abstract at http://www.arxiv.org/abs/eprint.

To use the template, you need only specify the arxiv or eprint parameter. Once you save the page, Citation bot will detect the citation and complete it automatically.

Common parameters, horizontal format

{{cite arXiv|last=|first=|author-link=|date=|title=|eprint=|class=}}

Common parameters, vertical format

• title: Title of the cited paper.
• arxiv or eprint (mandatory): arXiv/Eprint identifier, without any "arXiv:" prefix. Prior to April 2007, the identifiers included a classification, an optional two-letter subdivision, and a 7-digit YYMMNNN year, month, and sequence number of submission in that category. E.g. gr-qc/0610068 or math.GT/0309136. After April 2007, the format was changed to a simple YYMM.NNNN. Starting in January 2015, the identifier was changed to be 5 digits: YYMM.NNNNN.
• class: arXiv classification, e.g. hep-th. Optional. To be used only with new-style (2007 and later) eprint identifiers that do not include the classification.

The template uses the style of {{cite journal}}. Once a paper is accepted in a peer-reviewed journal, it is recommended to use one of those templates, as the peer-reviewed status of the article is important, while preserving the arXiv link in order to guarantee open access to the previous version of the article. To preserve the arXiv link, add e.g. |arxiv=gr-qc/0610068 or |arxiv=math.GT/0309136 or |arxiv=YYMM.NNNN (following the above examples) to the {{citation}} or {{cite journal}} templates.

Deprecated CS1/CS2 parameters

Recently removed CS1/CS2 parameters

Removed parameter	Replace with	Date	Note
|authors=	|lastn= / |firstn=, |authorn=, |vauthors=	August 2024

• last: Surname of a single author. Do not wikilink—use author-link instead. For corporate authors or authors for whom only one name is listed by the source, use last or one of its aliases (e.g. |author=Bono). Aliases: surname, author, last1, surname1, author1.
  • author: this parameter is used to hold the name of an organizational author (e.g. a committee) or the complete name (first and last) of a single person; for the latter, prefer the use of |first= and |last=. This parameter should never hold the names of more than one author. Supports accept-this-as-written markup. Do not use italics in this field, as doing so produces corrupt metadata.
  • first: Given or first names of author; for example: Firstname Middlename or Firstname M. or Firstname M. Sr. Do not wikilink—use author-link instead. Aliases: given, first1, given1. Requires last; first name will not display if last is empty. Use generational and regnal suffixes only in accordance with MOS:JRSR and use honorifics only in accordance with MOS:HON.
  • OR: for multiple authors, use last1, first1 through lastn, firstn, where n is any consecutive number for an unlimited number of authors (each firstn requires a corresponding lastn, but not the other way around). See the display parameters to change how many authors are displayed. Aliases: surname1, given1 through surnamen, givenn, or author1 through authorn. For an individual author plus an institutional author, you can use |first1=...|last1=...|author2=....
  • author-link: Title of existing Wikipedia article about the author—not the author's website; do not wikilink. Aliases: author-link1, author1-link, authorlink.
  • OR: for multiple authors, use author-link1 through author-linkn. Aliases: author1-link through authorn-link.
  • name-list-style: accepts a limited list of keywords as value; when set to amp, ampersand, or &, inserts an ampersand between the last two names in a name list; when set to and, inserts the conjunction 'and' between the last two names of a name list; when set to vancdisplays name lists in Vancouver style when the lists use the last/first forms of name parameters.
• vauthors: comma-separated list of author names in Vancouver style; enclose corporate or institutional author names in doubled parentheses. End with etal if appropriate:

  |vauthors=Smythe JB, ((Megabux Corp.)), etal

  • author-link and author-mask may be used for the individual names in |vauthors= as described above
• 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.

• 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.

• 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. Do not wikilink. Displays after the authors and is enclosed in parentheses. If there is no author, then displays after the website and publisher. For acceptable date formats, see Help:Citation Style 1 § Dates.

Shortened footnotes target full citations using the year specified in this parameter. A lowercase letter may be suffixed to the year to disambiguate {{sfn}} links to multiple works by the same author in the same year, unless the date is formatted as YYYY-MM-DD. In the latter case, year or ref is required to disambiguate the link targets.

For approximate year, precede with "c. ", like this: |date=c. 1900.

For no date, or "undated", use |date=n.d.

The date of a Web page, PDF, etc. with no visible date can sometimes be established by searching the page source or document code for a created or updated date; a comment for editors such as date=2021-12-25<!--date from page source-->|orig-date=Original date 2011-01-01 can be added.

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 publication. The more flexible |date= parameter also handles a year by itself. Do not use in combination with the |date= parameter, unless both of the following conditions are met:
  1. Shortened footnotes target multiple citations with same last name and year of publication. (This situation necessitates a CITEREF disambiguator, usually a lowercase letter suffixed to the year.)
  2. The |date= format is YYYY-MM-DD. (This format prevents the addition of a disambiguating letter to the 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

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

• title: Title of source. Displays in quotation marks. For titles containing quotation marks, convert regular quotation marks (") to single quotation marks ('). See MOS:QINQ for guidance in more complex situations.

Titles containing certain characters will not display and link correctly unless those characters are encoded.

newline	[	]	|
space	[	]	{{!}} (preferred)
	{{bracket|text}}		| or {{pipe}} – see also Help:Table § Rendering the pipe

• 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, e.g. espagnol at a French-language wiki instead of the English word "Spanish". Aliases: lang
