citation
The Citation template generates a citation for a book, periodical, contribution in a collective work, patent, or a web page.
Template documentation | This template is used on 189,000+ pages. To avoid large-scale disruption and unnecessary server load, any changes to this template should first be tested in its /sandbox or /testcases subpages, or in your own user space. The tested changes can then be added to this page in one single edit. Please consider discussing any changes on the talk page before implementing them. |
 | This template uses Lua: |
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 ... 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
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 when the url was accessed.
Example
{{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
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
Syntax
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.
Template:Citation Style documentation/sep comma
COinS
This template embeds COinS metadata in the HTML output, allowing reference management software to retrieve bibliographic metadata. Template:Hatnote inline/invoke As a general rule, only one data item per parameter. Do not include explanatory or alternate text:
- Use
|date=27 September 2007not|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=|issue=,|number=|page=,|pages=,|at=|edition=|publisher=,|distributor=,|institution=|url=|chapter-url=,|chapterurl=,|contribution-url=,|contributionurl=,|section-url=,|sectionurl=|author#=,|author-last#=,|author#-last=,|last#=,|surname#=|author-first#=,|author#-first=,|first#=,|given#=- any of the named identifiers (

Title
Template:Citation Style documentation/title Template:Citation Style documentation/chapter
- 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. Examples: Thesis, Booklet, Accepted manuscript, CD liner, Press release. Alias: medium.
- 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 Wiki 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.
Date
- date: Date of source being referenced. 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. Required when year is used to disambiguate
{{sfn}}links to multiple-work citations by the same author in the same year.[more] Do not wikilink. Displays after the authors and is enclosed in parentheses. If there is no author, then displays after publisher. Template:Hatnote inline/invoke
- For approximate year, precede with "
c.", like this:|date=c. 1900.
- For no date, or "undated", add as
|date=n.d.
- year: Year of source being referenced. Use of
|date=is recommended unless all of the following conditions are met:- The template uses
|ref=harv, or the template is{{citation}}, or|mode=cs2 - The
|date=format is YYYY-MM-DD. - The citation requires a
CITEREFdisambiguator.
- The template uses
- orig-year: Original publication year; displays after the date or year. For clarity, please supply specifics. For example:
|orig-year=First published 1859or|orig-year=Composed 1904. Alias: origyear - df: date format; sets rendered dates to the specified format; does not support date ranges or seasonal dates. 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 formatymd– as above for year initial numeric format YYYY-MM-DDdmy-all– set publication, access-, and archive-dates to day month year format;mdy-all– as above for month day, year formatymd-all– as above for year initial numeric format YYYY-MM-DD
Periodical
Template:Citation Style documentation/journal
Publisher
- publisher: Name of publisher; may be wikilinked if relevant. The publisher is the company that publishes the work being cited. Do not use the publisher parameter for the name of a work (e.g. a website, book, encyclopedia, newspaper, magazine, journal, etc.). 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: 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
- publication-place: If any one of publication-place, place, or location is defined, the location 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 year or date are defined and only if different, else publication-date is used and displayed as date. Use the same format as other dates in the article; do not wikilink. Follows publisher; if work is not defined, then publication-date is preceded by "published" and enclosed in parenthesis.
- 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. Template:Hatnote inline/invoke
Edition, series, volume
Template:Citation Style documentation/edition
- 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.
Template:Citation Style documentation/volume
In-source locations
- page: The number of a single page in the source that supports the content. Use either
|page=or|pages=, but not both. Displays preceded byp.
|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 bypp.
|nopp=y. Hyphens are automatically converted to en dashes; if hyphens are appropriate, for example: pp. 3-1–3-15, use|pages=3{{hyphen}}1–3{{hyphen}}15or|at=pp. 3-1–3-15.- nopp: Set to y, yes, or true to suppress the
p.
pp.
|page=Front coveror|pages=passim.
- nopp: Set to y, yes, or true to suppress the
- OR: at: For sources where a page number is inappropriate or insufficient. Overridden by
|page=or|pages=. Use only one of|page=,|pages=, or|at=.
- Examples: page (p.) or pages (pp.); section (sec.), column (col.), paragraph (para.); track; hours, minutes and seconds; act, scene, canto, book, part, folio, stanza, back cover, liner notes, indicia, colophon, dust jacket, verse.
URL
- 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.
#ixzz2rBr3aO94or?utm_source=google&utm_medium=...&utm_term=...&utm_campaign=.... Template:Hatnote inline/invoke Do not link to any commercial booksellers, such as Amazon.com; 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. 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. 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 Template:Hatnote inline/invoke, WebCite Template:Hatnote inline/invoke and archive.is Template:Hatnote inline/invoke; 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: 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. Do not wikilink; templated dates are discouraged. Alias: archivedate.
- dead-url: the default value of this optional parameter, if omitted, is
|dead-url=yes; equivalent values are y or true. Ignored if archive-url is not set. 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=unfitor|dead-url=usurpedsuppresses display of the original URL (but|url=and|archive-url=are 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=trueto disable categorization; mainly used for documentation where the error is demonstrated. Alias: no-cat.
- 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://andhttps://will be supported by all browsers; however,ftp://,gopher://,irc://,ircs://,mailto:andnews: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.
Chapter URL
Template:Citation Style documentation/chapterurl
Anchor
Template:Citation Style documentation/ref2
Identifiers
- id: A unique identifier, used where none of the specialized identifiers are applicable; wikilink or use a template as applicable. For example,
|id=NCJ 122967will append "NCJ 122967" at the end of the citation. You can use templates such as|id={{NCJ|122967}}to append NCJ 122967 instead.
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) orarxiv=0706.0001(April 2007 – December 2014) orarxiv=1501.00001(since January 2015). 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, include it only if standard identifiers are not available. Example
asin=B00005N5PF- 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
- asin-tld: ASIN top-level domain for Amazon sites other than the US; valid values:
- 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.
078733for 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.
10.1.1.176.341for 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 (10.
- 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-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; example
eissn=1557-2986Alias: EISSN - hdl: Handle System identifier for digital objects and other resources on the Internet; example
hdl=20.1000/100Alias: HDL - isbn: International Standard Book Number; for example:
978-0-8126-9593-9. Template:Hatnote inline/invoke 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; example

|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}}, - 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=2will display only the first two authors in a citation. By default, all authors are displayed.|display-authors=etaldisplays 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=2will display only the first two editors in a citation. By default, all editors are displayed.|display-editors=etaldisplays 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 toy,yes, ortrue. Example:|last-author-amp=yes - postscript: Controls the closing punctuation for a citation; defaults to none. Ignored if quote is defined.
Subscription or registration required
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:
free: the source is free to read for anyone (this applies in particular to articles in open access)
registration: a free registration is required to access the source-
limited: there are other constraints (such as a cap on daily views) to freely access this source 
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
Some identifiers always link to free full texts. In this case, the access level is automatically indicated by the template. This is the case for |arxiv=, |biorxiv=, |citeseerx=, |pmc=, |rfc= and |ssrn=.
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(ory, ortrue); superseded by subscription if both are set. - subscription: For online sources that require a subscription, set
|subscription=yes(ory, ortrue); supersedes registration if both are set.
Setting |registration= or |subscription= to any value other than y, yes, or true will generate an error message.

Anchored citations
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
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 "Template:Harvid".
Related methods which leave only a number in the text are to use the {{harvnb}} template enclosed in the html code, or to use the {{sfn}} template alone. The example above would be {{harvnb|Wright|Evans|1851|p=ix}} or {{sfn|Wright|Evans|1851|p=ix}} both of which generate a footnote, such as
- 17. Template:Harvnb
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
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:
- Montes, G.; Halterman, J. S. (2008a), "Association of Childhood Autism Spectrum Disorders and Loss of Family Income", Pediatrics, 121 (4): e821–e826, doi:10.1542/peds.2007-1594, PMID 18381511
- Montes, G.; Halterman, J. S. (2008b), "Child Care Problems and Employment Among Families with Preschool-aged Children with Autism in the United States", Pediatrics, 122 (1): e202–e208, doi:10.1542/peds.2007-3037, PMID 18595965
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.

TemplateData for Citation
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.
