Template:Citation

For the ^{[citation needed]} template, see {{citation needed}}.

The Citation template generates a citation for a book, periodical, contribution in a collective work, patent, or a web page. It determines the citation type by examining which parameters are used.

If invoked with the right parameters, this template produces output identical to that of the Cite templates, such as {{Cite book}} and {{Cite web}}. The default behavior sometimes differs from that of the Cite templates; for example, this template by default generates anchors for Harvard references whereas the Cite templates do not (although they can be made to do so), and this template by default uses commas to separate some fields that the Cite templates separate with periods (full stops).

The template should be inserted after punctuation, such as a period or comma.

All parameter names are lowercase.

Simple citation

This template gives the most commonly used attributes. You can copy the horizontal form or vertical form below and then add in extra attributes from the full list. Spacing and ordering is irrelevant.

{{Citation |last= |first= |year= |title= |publisher= |publication-place= |page= |url= |accessdate= }}

{{Citation | last = | first = | year = | title = | publisher = | publication-place = | page = | url = | accessdate = }}

• last: The author's surname or last name. Don't use with author.
• first: The author's first or given name(s).
• year: Year of authorship or publication. Mandatory for use with links from Template:Harvard citation, unless Template:Para specifies both month and year.
• title: Title of the work. Mandatory for web references.
• publisher: The name of the publisher. Omit terms such as Publishers, Co., Inc., Ltd., etc., but retain the words Books or Press.
  • publication-place (or place): The city of publication. If more than one town/city is listed on the title page, give the first one or the location of the publisher's head office.
• page: For use when one page is cited. Adds "p." before the page number. Do not use with pages.
• url: An url of an online location where the item can be found. If the url includes double quotes, these must be encoded as "%22".
  • accessdate: Date when the url was accessed.

It does this by creating an HTML anchor containing an ID. The special parameter Template:Para generates an ID suitable for Harvard referencing templates such as {{harv}} as specified in the next section; this is the default for the {{citation}} template. If an empty Template:Para is given, no anchor is generated; this is the default for the Cite templates such as {{cite book}} and {{cite news}}. You can also specify the ID directly, using the Template:Para 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: 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 and the year of the cited source. For example, the markup "{{harv|Wright|Evans|1851|p=ix}}" generates the Harvard reference "Template:Harv", 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}} 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 <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. 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 Template:Para (or Template:Para), Template:Para, Template:Para, and Template:Para, and similarly for Template:Para etc. and for Template:Para 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 "Template:Para" with "Template:Para Template:Para", or add "Template:Para" to the {{citation}} invocation, or add the same ref parameter (say, "Template:Para") to both the {{citation}} and the {{harv}} invocations. Similarly, the year is used, as specified by Template:Para. If no year is given, this template attempts to derive the year from Template:Para (or, if no date is given, from Template:Para) by applying the MediaWiki#time function. This heuristic works with many common date formats (American, International and ISO standard format YYYY-MM-DD as listed in WP:MOS), but may not work as expected with other formats, so when in doubt it may be safer to use Template:Para. Note that if only a year, say 2005, is known you must use Template:Para rather than Template:Para. 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: 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., "Template:Para" and "Template:Para", 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.

It does this by creating an HTML anchor containing an ID. The special parameter Template:Para generates an ID suitable for Harvard referencing templates such as {{harv}} as specified in the next section; this is the default for the {{citation}} template. If an empty Template:Para is given, no anchor is generated; this is the default for the Cite templates such as {{cite book}} and {{cite news}}. You can also specify the ID directly, using the Template:Para 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: 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 and the year of the cited source. For example, the markup "{{harv|Wright|Evans|1851|p=ix}}" generates the Harvard reference "Template:Harv", 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}} 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 <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. 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 Template:Para (or Template:Para), Template:Para, Template:Para, and Template:Para, and similarly for Template:Para etc. and for Template:Para 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 "Template:Para" with "Template:Para Template:Para", or add "Template:Para" to the {{citation}} invocation, or add the same ref parameter (say, "Template:Para") to both the {{citation}} and the {{harv}} invocations. Similarly, the year is used, as specified by Template:Para. If no year is given, this template attempts to derive the year from Template:Para (or, if no date is given, from Template:Para) by applying the MediaWiki#time function. This heuristic works with many common date formats (American, International and ISO standard format YYYY-MM-DD as listed in WP:MOS), but may not work as expected with other formats, so when in doubt it may be safer to use Template:Para. Note that if only a year, say 2005, is known you must use Template:Para rather than Template:Para. 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: 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., "Template:Para" and "Template:Para", as was done above. Any Harvard references to these citations should use years with the same suffixes.

The Citation template generates a citation for a book, periodical, contribution in a collective work, patent, or a web page. It determines the citation type by examining which parameters are used. If invoked with the right parameters, this template produces output identical to that of the Cite templates, such as {{Cite book}} and {{Cite web}}. The default behavior sometimes differs from that of the Cite templates; for example, this template by default generates anchors for Harvard references whereas the Cite templates do not (although they can be made to do so), and this template by default uses commas to separate some fields that the Cite templates separate with periods (full stops). The template should be inserted after punctuation, such as a period or comma. All parameter names are lowercase. Simple citation This template gives the most commonly used attributes. You can copy the horizontal form or vertical form below and then add in extra attributes from the full list. Spacing and ordering is irrelevant. {{Citation |last= |first= |year= |title= |publisher= |publication-place= |page= |url= |accessdate= }} {{Citation | last = | first = | year = | title = | publisher = | publication-place = | page = | url = | accessdate = }} last: The author's surname or last name. Don't use with author. first: The author's first or given name(s). year: Year of authorship or publication. Mandatory for use with links from Template:Harvard citation, unless Template:Para specifies both month and year. title: Title of the work. Mandatory for web references. publisher: The name of the publisher. Omit terms such as Publishers, Co., Inc., Ltd., etc., but retain the words Books or Press. publication-place (or place): The city of publication. If more than one town/city is listed on the title page, give the first one or the location of the publisher's head office. page: For use when one page is cited. Adds "p." before the page number. Do not use with pages. url: An url of an online location where the item can be found. If the url includes double quotes, these must be encoded as "%22". accessdate: Date 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 | id = {{OL|7120924W}} }} Full citation parameters These can be used for all types of publication except patents.

It does this by creating an HTML anchor containing an ID. The special parameter Template:Para generates an ID suitable for Harvard referencing templates such as {{harv}} as specified in the next section; this is the default for the {{citation}} template. If an empty Template:Para is given, no anchor is generated; this is the default for the Cite templates such as {{cite book}} and {{cite news}}. You can also specify the ID directly, using the Template:Para 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: 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 and the year of the cited source. For example, the markup "{{harv|Wright|Evans|1851|p=ix}}" generates the Harvard reference "Template:Harv", 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}} 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 <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. 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 Template:Para (or Template:Para), Template:Para, Template:Para, and Template:Para, and similarly for Template:Para etc. and for Template:Para 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 "Template:Para" with "Template:Para Template:Para", or add "Template:Para" to the {{citation}} invocation, or add the same ref parameter (say, "Template:Para") to both the {{citation}} and the {{harv}} invocations. Similarly, the year is used, as specified by Template:Para. If no year is given, this template attempts to derive the year from Template:Para (or, if no date is given, from Template:Para) by applying the MediaWiki#time function. This heuristic works with many common date formats (American, International and ISO standard format YYYY-MM-DD as listed in WP:MOS), but may not work as expected with other formats, so when in doubt it may be safer to use Template:Para. Note that if only a year, say 2005, is known you must use Template:Para rather than Template:Para. 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: 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., "Template:Para" and "Template:Para", 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.

The Citation template generates a citation for a book, periodical, contribution in a collective work, patent, or a web page. It determines the citation type by examining which parameters are used. If invoked with the right parameters, this template produces output identical to that of the Cite templates, such as {{Cite book}} and {{Cite web}}. The default behavior sometimes differs from that of the Cite templates; for example, this template by default generates anchors for Harvard references whereas the Cite templates do not (although they can be made to do so), and this template by default uses commas to separate some fields that the Cite templates separate with periods (full stops). The template should be inserted after punctuation, such as a period or comma. All parameter names are lowercase. Simple citation This template gives the most commonly used attributes. You can copy the horizontal form or vertical form below and then add in extra attributes from the full list. Spacing and ordering is irrelevant. {{Citation |last= |first= |year= |title= |publisher= |publication-place= |page= |url= |accessdate= }} {{Citation | last = | first = | year = | title = | publisher = | publication-place = | page = | url = | accessdate = }} last: The author's surname or last name. Don't use with author. first: The author's first or given name(s). year: Year of authorship or publication. Mandatory for use with links from Template:Harvard citation, unless Template:Para specifies both month and year. title: Title of the work. Mandatory for web references. publisher: The name of the publisher. Omit terms such as Publishers, Co., Inc., Ltd., etc., but retain the words Books or Press. publication-place (or place): The city of publication. If more than one town/city is listed on the title page, give the first one or the location of the publisher's head office. page: For use when one page is cited. Adds "p." before the page number. Do not use with pages. url: An url of an online location where the item can be found. If the url includes double quotes, these must be encoded as "%22". accessdate: Date when the url was accessed.

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., "Template:Para" and "Template:Para", 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.

The Citation template generates a citation for a book, periodical, contribution in a collective work, patent, or a web page. It determines the citation type by examining which parameters are used. If invoked with the right parameters, this template produces output identical to that of the Cite templates, such as {{Cite book}} and {{Cite web}}. The default behavior sometimes differs from that of the Cite templates; for example, this template by default generates anchors for Harvard references whereas the Cite templates do not (although they can be made to do so), and this template by default uses commas to separate some fields that the Cite templates separate with periods (full stops). The template should be inserted after punctuation, such as a period or comma. All parameter names are lowercase. Simple citation This template gives the most commonly used attributes. You can copy the horizontal form or vertical form below and then add in extra attributes from the full list. Spacing and ordering is irrelevant. {{Citation |last= |first= |year= |title= |publisher= |publication-place= |page= |url= |accessdate= }} {{Citation | last = | first = | year = | title = | publisher = | publication-place = | page = | url = | accessdate = }} last: The author's surname or last name. Don't use with author. first: The author's first or given name(s). year: Year of authorship or publication. Mandatory for use with links from Template:Harvard citation, unless Template:Para specifies both month and year. title: Title of the work. Mandatory for web references. publisher: The name of the publisher. Omit terms such as Publishers, Co., Inc., Ltd., etc., but retain the words Books or Press. publication-place (or place): The city of publication. If more than one town/city is listed on the title page, give the first one or the location of the publisher's head office. page: For use when one page is cited. Adds "p." before the page number. Do not use with pages. url: An url of an online location where the item can be found. If the url includes double quotes, these must be encoded as "%22". accessdate: Date 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 | id = {{OL|7120924W}} }} Full citation parameters These can be used for all types of publication except patents.

It does this by creating an HTML anchor containing an ID. The special parameter Template:Para generates an ID suitable for Harvard referencing templates such as {{harv}} as specified in the next section; this is the default for the {{citation}} template. If an empty Template:Para is given, no anchor is generated; this is the default for the Cite templates such as {{cite book}} and {{cite news}}. You can also specify the ID directly, using the Template:Para 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: 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 and the year of the cited source. For example, the markup "{{harv|Wright|Evans|1851|p=ix}}" generates the Harvard reference "Template:Harv", 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}} 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 <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. 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 Template:Para (or Template:Para), Template:Para, Template:Para, and Template:Para, and similarly for Template:Para etc. and for Template:Para 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 "Template:Para" with "Template:Para Template:Para", or add "Template:Para" to the {{citation}} invocation, or add the same ref parameter (say, "Template:Para") to both the {{citation}} and the {{harv}} invocations. Similarly, the year is used, as specified by Template:Para. If no year is given, this template attempts to derive the year from Template:Para (or, if no date is given, from Template:Para) by applying the MediaWiki#time function. This heuristic works with many common date formats (American, International and ISO standard format YYYY-MM-DD as listed in WP:MOS), but may not work as expected with other formats, so when in doubt it may be safer to use Template:Para. Note that if only a year, say 2005, is known you must use Template:Para rather than Template:Para. 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: 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., "Template:Para" and "Template:Para", 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.

For example, the markup "{{harv|Wright|Evans|1851|p=ix}}" generates the Harvard reference "Template:Harv", 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}} 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 <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. 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 Template:Para (or Template:Para), Template:Para, Template:Para, and Template:Para, and similarly for Template:Para etc. and for Template:Para 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 "Template:Para" with "Template:Para Template:Para", or add "Template:Para" to the {{citation}} invocation, or add the same ref parameter (say, "Template:Para") to both the {{citation}} and the {{harv}} invocations. Similarly, the year is used, as specified by Template:Para. If no year is given, this template attempts to derive the year from Template:Para (or, if no date is given, from Template:Para) by applying the MediaWiki#time function. This heuristic works with many common date formats (American, International and ISO standard format YYYY-MM-DD as listed in WP:MOS), but may not work as expected with other formats, so when in doubt it may be safer to use Template:Para. Note that if only a year, say 2005, is known you must use Template:Para rather than Template:Para. 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: 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., "Template:Para" and "Template:Para", 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.

It does this by creating an HTML anchor containing an ID. The special parameter Template:Para generates an ID suitable for Harvard referencing templates such as {{harv}} as specified in the next section; this is the default for the {{citation}} template. If an empty Template:Para is given, no anchor is generated; this is the default for the Cite templates such as {{cite book}} and {{cite news}}. You can also specify the ID directly, using the Template:Para 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: 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 and the year of the cited source. For example, the markup "{{harv|Wright|Evans|1851|p=ix}}" generates the Harvard reference "Template:Harv", 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}} 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 <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. 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 Template:Para (or Template:Para), Template:Para, Template:Para, and Template:Para, and similarly for Template:Para etc. and for Template:Para 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 "Template:Para" with "Template:Para Template:Para", or add "Template:Para" to the {{citation}} invocation, or add the same ref parameter (say, "Template:Para") to both the {{citation}} and the {{harv}} invocations. Similarly, the year is used, as specified by Template:Para. If no year is given, this template attempts to derive the year from Template:Para (or, if no date is given, from Template:Para) by applying the MediaWiki#time function. This heuristic works with many common date formats (American, International and ISO standard format YYYY-MM-DD as listed in WP:MOS), but may not work as expected with other formats, so when in doubt it may be safer to use Template:Para.

It does this by creating an HTML anchor containing an ID. The special parameter Template:Para generates an ID suitable for Harvard referencing templates such as {{harv}} as specified in the next section; this is the default for the {{citation}} template. If an empty Template:Para is given, no anchor is generated; this is the default for the Cite templates such as {{cite book}} and {{cite news}}. You can also specify the ID directly, using the Template:Para 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: 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 and the year of the cited source. For example, the markup "{{harv|Wright|Evans|1851|p=ix}}" generates the Harvard reference "Template:Harv", 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}} 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 <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. 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 Template:Para (or Template:Para), Template:Para, Template:Para, and Template:Para, and similarly for Template:Para etc. and for Template:Para 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 "Template:Para" with "Template:Para Template:Para", or add "Template:Para" to the {{citation}} invocation, or add the same ref parameter (say, "Template:Para") to both the {{citation}} and the {{harv}} invocations. Similarly, the year is used, as specified by Template:Para. If no year is given, this template attempts to derive the year from Template:Para (or, if no date is given, from Template:Para) by applying the MediaWiki#time function. This heuristic works with many common date formats (American, International and ISO standard format YYYY-MM-DD as listed in WP:MOS), but may not work as expected with other formats, so when in doubt it may be safer to use Template:Para. Note that if only a year, say 2005, is known you must use Template:Para rather than Template:Para. 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: 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., "Template:Para" and "Template:Para", as was done above. Any Harvard references to these citations should use years with the same suffixes.

The Citation template generates a citation for a book, periodical, contribution in a collective work, patent, or a web page. It determines the citation type by examining which parameters are used. If invoked with the right parameters, this template produces output identical to that of the Cite templates, such as {{Cite book}} and {{Cite web}}. The default behavior sometimes differs from that of the Cite templates; for example, this template by default generates anchors for Harvard references whereas the Cite templates do not (although they can be made to do so), and this template by default uses commas to separate some fields that the Cite templates separate with periods (full stops). The template should be inserted after punctuation, such as a period or comma. All parameter names are lowercase. Simple citation This template gives the most commonly used attributes. You can copy the horizontal form or vertical form below and then add in extra attributes from the full list. Spacing and ordering is irrelevant. {{Citation |last= |first= |year= |title= |publisher= |publication-place= |page= |url= |accessdate= }} {{Citation | last = | first = | year = | title = | publisher = | publication-place = | page = | url = | accessdate = }} last: The author's surname or last name. Don't use with author. first: The author's first or given name(s). year: Year of authorship or publication. Mandatory for use with links from Template:Harvard citation, unless Template:Para specifies both month and year. title: Title of the work. Mandatory for web references. publisher: The name of the publisher. Omit terms such as Publishers, Co., Inc., Ltd., etc., but retain the words Books or Press. publication-place (or place): The city of publication. If more than one town/city is listed on the title page, give the first one or the location of the publisher's head office. page: For use when one page is cited. Adds "p." before the page number. Do not use with pages. url: An url of an online location where the item can be found. If the url includes double quotes, these must be encoded as "%22". accessdate: Date 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 | id = {{OL|7120924W}} }} Full citation parameters These can be used for all types of publication except patents.

Omit or leave blank to remove the trailing full stop (period). Punctuation specified by this parameter will appear within the cite span, and consequently before any icons added by metadata-using software, e.g. library browser plugins. Hence this parameter should be used instead of manually appending data to the citation. This parameter is ignored if Template:Para is specified, when Template:Para is forced.

It does this by creating an HTML anchor containing an ID. The special parameter Template:Para generates an ID suitable for Harvard referencing templates such as {{harv}} as specified in the next section; this is the default for the {{citation}} template. If an empty Template:Para is given, no anchor is generated; this is the default for the Cite templates such as {{cite book}} and {{cite news}}. You can also specify the ID directly, using the Template:Para 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: 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 and the year of the cited source. For example, the markup "{{harv|Wright|Evans|1851|p=ix}}" generates the Harvard reference "Template:Harv", 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}} 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 <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. 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 Template:Para (or Template:Para), Template:Para, Template:Para, and Template:Para, and similarly for Template:Para etc. and for Template:Para 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 "Template:Para" with "Template:Para Template:Para", or add "Template:Para" to the {{citation}} invocation, or add the same ref parameter (say, "Template:Para") to both the {{citation}} and the {{harv}} invocations. Similarly, the year is used, as specified by Template:Para. If no year is given, this template attempts to derive the year from Template:Para (or, if no date is given, from Template:Para) by applying the MediaWiki#time function. This heuristic works with many common date formats (American, International and ISO standard format YYYY-MM-DD as listed in WP:MOS), but may not work as expected with other formats, so when in doubt it may be safer to use Template:Para. Note that if only a year, say 2005, is known you must use Template:Para rather than Template:Para. 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: 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., "Template:Para" and "Template:Para", 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.

The Citation template generates a citation for a book, periodical, contribution in a collective work, patent, or a web page. It determines the citation type by examining which parameters are used. If invoked with the right parameters, this template produces output identical to that of the Cite templates, such as {{Cite book}} and {{Cite web}}. The default behavior sometimes differs from that of the Cite templates; for example, this template by default generates anchors for Harvard references whereas the Cite templates do not (although they can be made to do so), and this template by default uses commas to separate some fields that the Cite templates separate with periods (full stops). The template should be inserted after punctuation, such as a period or comma. All parameter names are lowercase. Simple citation This template gives the most commonly used attributes. You can copy the horizontal form or vertical form below and then add in extra attributes from the full list. Spacing and ordering is irrelevant. {{Citation |last= |first= |year= |title= |publisher= |publication-place= |page= |url= |accessdate= }} {{Citation | last = | first = | year = | title = | publisher = | publication-place = | page = | url = | accessdate = }} last: The author's surname or last name. Don't use with author. first: The author's first or given name(s). year: Year of authorship or publication. Mandatory for use with links from Template:Harvard citation, unless Template:Para specifies both month and year. title: Title of the work. Mandatory for web references. publisher: The name of the publisher. Omit terms such as Publishers, Co., Inc., Ltd., etc., but retain the words Books or Press. publication-place (or place): The city of publication. If more than one town/city is listed on the title page, give the first one or the location of the publisher's head office. page: For use when one page is cited. Adds "p." before the page number. Do not use with pages. url: An url of an online location where the item can be found. If the url includes double quotes, these must be encoded as "%22". accessdate: Date 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 | id = {{OL|7120924W}} }} Full citation parameters These can be used for all types of publication except patents.

To avoid this problem, distinguish the citations by appending suffixes to the years, e.g., "Template:Para" and "Template:Para", 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.

The Citation template generates a citation for a book, periodical, contribution in a collective work, patent, or a web page. It determines the citation type by examining which parameters are used. If invoked with the right parameters, this template produces output identical to that of the Cite templates, such as {{Cite book}} and {{Cite web}}. The default behavior sometimes differs from that of the Cite templates; for example, this template by default generates anchors for Harvard references whereas the Cite templates do not (although they can be made to do so), and this template by default uses commas to separate some fields that the Cite templates separate with periods (full stops). The template should be inserted after punctuation, such as a period or comma. All parameter names are lowercase. Simple citation This template gives the most commonly used attributes. You can copy the horizontal form or vertical form below and then add in extra attributes from the full list. Spacing and ordering is irrelevant. {{Citation |last= |first= |year= |title= |publisher= |publication-place= |page= |url= |accessdate= }} {{Citation | last = | first = | year = | title = | publisher = | publication-place = | page = | url = | accessdate = }} last: The author's surname or last name. Don't use with author. first: The author's first or given name(s). year: Year of authorship or publication. Mandatory for use with links from Template:Harvard citation, unless Template:Para specifies both month and year. title: Title of the work. Mandatory for web references. publisher: The name of the publisher. Omit terms such as Publishers, Co., Inc., Ltd., etc., but retain the words Books or Press. publication-place (or place): The city of publication. If more than one town/city is listed on the title page, give the first one or the location of the publisher's head office. page: For use when one page is cited. Adds "p." before the page number. Do not use with pages. url: An url of an online location where the item can be found. If the url includes double quotes, these must be encoded as "%22". accessdate: Date 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 | id = {{OL|7120924W}} }} Full citation parameters These can be used for all types of publication except patents.

It does this by creating an HTML anchor containing an ID. The special parameter Template:Para generates an ID suitable for Harvard referencing templates such as {{harv}} as specified in the next section; this is the default for the {{citation}} template. If an empty Template:Para is given, no anchor is generated; this is the default for the Cite templates such as {{cite book}} and {{cite news}}. You can also specify the ID directly, using the Template:Para 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: 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 and the year of the cited source. For example, the markup "{{harv|Wright|Evans|1851|p=ix}}" generates the Harvard reference "Template:Harv", 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}} 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 <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. 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 Template:Para (or Template:Para), Template:Para, Template:Para, and Template:Para, and similarly for Template:Para etc. and for Template:Para 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 "Template:Para" with "Template:Para Template:Para", or add "Template:Para" to the {{citation}} invocation, or add the same ref parameter (say, "Template:Para") to both the {{citation}} and the {{harv}} invocations. Similarly, the year is used, as specified by Template:Para. If no year is given, this template attempts to derive the year from Template:Para (or, if no date is given, from Template:Para) by applying the MediaWiki#time function. This heuristic works with many common date formats (American, International and ISO standard format YYYY-MM-DD as listed in WP:MOS), but may not work as expected with other formats, so when in doubt it may be safer to use Template:Para. Note that if only a year, say 2005, is known you must use Template:Para rather than Template:Para. 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: 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., "Template:Para" and "Template:Para", 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.

For example, the markup "{{harv|Wright|Evans|1851|p=ix}}" generates the Harvard reference "Template:Harv", 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}} 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 <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. 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 Template:Para (or Template:Para), Template:Para, Template:Para, and Template:Para, and similarly for Template:Para etc. and for Template:Para 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 "Template:Para" with "Template:Para Template:Para", or add "Template:Para" to the {{citation}} invocation, or add the same ref parameter (say, "Template:Para") to both the {{citation}} and the {{harv}} invocations. Similarly, the year is used, as specified by Template:Para. If no year is given, this template attempts to derive the year from Template:Para (or, if no date is given, from Template:Para) by applying the MediaWiki#time function. This heuristic works with many common date formats (American, International and ISO standard format YYYY-MM-DD as listed in WP:MOS), but may not work as expected with other formats, so when in doubt it may be safer to use Template:Para. Note that if only a year, say 2005, is known you must use Template:Para rather than Template:Para. 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: 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., "Template:Para" and "Template:Para", 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.

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 Template:Para generates an ID suitable for Harvard referencing templates such as {{harv}} as specified in the next section; this is the default for the {{citation}} template. If an empty Template:Para is given, no anchor is generated; this is the default for the Cite templates such as {{cite book}} and {{cite news}}. You can also specify the ID directly, using the Template:Para 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:

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 and the year of the cited source. For example, the markup "{{harv|Wright|Evans|1851|p=ix}}" generates the Harvard reference "Template:Harv", 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}}

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 <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. 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 Template:Para (or Template:Para), Template:Para, Template:Para, and Template:Para, and similarly for Template:Para etc. and for Template:Para 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 "Template:Para" with "Template:Para Template:Para", or add "Template:Para" to the {{citation}} invocation, or add the same ref parameter (say, "Template:Para") to both the {{citation}} and the {{harv}} invocations.

Similarly, the year is used, as specified by Template:Para. If no year is given, this template attempts to derive the year from Template:Para (or, if no date is given, from Template:Para) by applying the MediaWiki#time function. This heuristic works with many common date formats (American, International and ISO standard format YYYY-MM-DD as listed in WP:MOS), but may not work as expected with other formats, so when in doubt it may be safer to use Template:Para. Note that if only a year, say 2005, is known you must use Template:Para rather than Template:Para.

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:

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., "Template:Para" and "Template:Para", 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.

Tools

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

Template:Visible anchor

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 and the year of the cited source. For example, the markup "{{harv|Wright|Evans|1851|p=ix}}" generates the Harvard reference "Template:Harv", 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}}

For the ^{[citation needed]} template, see {{citation needed}}.

The Citation template generates a citation for a book, periodical, contribution in a collective work, patent, or a web page. It determines the citation type by examining which parameters are used.

If invoked with the right parameters, this template produces output identical to that of the Cite templates, such as {{Cite book}} and {{Cite web}}. The default behavior sometimes differs from that of the Cite templates; for example, this template by default generates anchors for Harvard references whereas the Cite templates do not (although they can be made to do so), and this template by default uses commas to separate some fields that the Cite templates separate with periods (full stops).

The template should be inserted after punctuation, such as a period or comma.

All parameter names are lowercase.

Simple citation

This template gives the most commonly used attributes. You can copy the horizontal form or vertical form below and then add in extra attributes from the full list. Spacing and ordering is irrelevant.

{{Citation |last= |first= |year= |title= |publisher= |publication-place= |page= |url= |accessdate= }}

{{Citation | last = | first = | year = | title = | publisher = | publication-place = | page = | url = | accessdate = }}

• last: The author's surname or last name. Don't use with author.
• first: The author's first or given name(s).
• year: Year of authorship or publication. Mandatory for use with links from Template:Harvard citation, unless Template:Para specifies both month and year.
• title: Title of the work. Mandatory for web references.
• publisher: The name of the publisher. Omit terms such as Publishers, Co., Inc., Ltd., etc., but retain the words Books or Press.
  • publication-place (or place): The city of publication. If more than one town/city is listed on the title page, give the first one or the location of the publisher's head office.
• page: For use when one page is cited. Adds "p." before the page number. Do not use with pages.
• url: An url of an online location where the item can be found. If the url includes double quotes, these must be encoded as "%22".
  • accessdate: Date 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 | id = {{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

Description

Display options

• postscript: Set terminal punctuation. Omit or leave blank to remove the trailing full stop (period). Punctuation specified by this parameter will appear within the cite span, and consequently before any icons added by metadata-using software, e.g. library browser plugins. Hence this parameter should be used instead of manually appending data to the citation. This parameter is ignored if Template:Para is specified, when Template:Para is forced.

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 Template:Para generates an ID suitable for Harvard referencing templates such as {{harv}} as specified in the next section; this is the default for the {{citation}} template. If an empty Template:Para is given, no anchor is generated; this is the default for the Cite templates such as {{cite book}} and {{cite news}}. You can also specify the ID directly, using the Template:Para 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:

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 and the year of the cited source. For example, the markup "{{harv|Wright|Evans|1851|p=ix}}" generates the Harvard reference "Template:Harv", 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}}

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 <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. 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 Template:Para (or Template:Para), Template:Para, Template:Para, and Template:Para, and similarly for Template:Para etc. and for Template:Para 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 "Template:Para" with "Template:Para Template:Para", or add "Template:Para" to the {{citation}} invocation, or add the same ref parameter (say, "Template:Para") to both the {{citation}} and the {{harv}} invocations.

Similarly, the year is used, as specified by Template:Para. If no year is given, this template attempts to derive the year from Template:Para (or, if no date is given, from Template:Para) by applying the MediaWiki#time function. This heuristic works with many common date formats (American, International and ISO standard format YYYY-MM-DD as listed in WP:MOS), but may not work as expected with other formats, so when in doubt it may be safer to use Template:Para. Note that if only a year, say 2005, is known you must use Template:Para rather than Template:Para.

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:

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., "Template:Para" and "Template:Para", 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.

Parameters

Description

Display options

• postscript: Set terminal punctuation. Omit or leave blank to remove the trailing full stop (period). Punctuation specified by this parameter will appear within the cite span, and consequently before any icons added by metadata-using software, e.g. library browser plugins. Hence this parameter should be used instead of manually appending data to the citation. This parameter is ignored if Template:Para is specified, when Template:Para is forced.

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 Template:Para generates an ID suitable for Harvard referencing templates such as {{harv}} as specified in the next section; this is the default for the {{citation}} template. If an empty Template:Para is given, no anchor is generated; this is the default for the Cite templates such as {{cite book}} and {{cite news}}. You can also specify the ID directly, using the Template:Para 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:

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 and the year of the cited source. For example, the markup "{{harv|Wright|Evans|1851|p=ix}}" generates the Harvard reference "Template:Harv", 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}}

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 <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. 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 Template:Para (or Template:Para), Template:Para, Template:Para, and Template:Para, and similarly for Template:Para etc. and for Template:Para 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 "Template:Para" with "Template:Para Template:Para", or add "Template:Para" to the {{citation}} invocation, or add the same ref parameter (say, "Template:Para") to both the {{citation}} and the {{harv}} invocations.

Similarly, the year is used, as specified by Template:Para. If no year is given, this template attempts to derive the year from Template:Para (or, if no date is given, from Template:Para) by applying the MediaWiki#time function. This heuristic works with many common date formats (American, International and ISO standard format YYYY-MM-DD as listed in WP:MOS), but may not work as expected with other formats, so when in doubt it may be safer to use Template:Para. Note that if only a year, say 2005, is known you must use Template:Para rather than Template:Para.

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:

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., "Template:Para" and "Template:Para", 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.

Tools

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

Template:Visible anchor

For the ^{[citation needed]} template, see {{citation needed}}.

The Citation template generates a citation for a book, periodical, contribution in a collective work, patent, or a web page. It determines the citation type by examining which parameters are used.

If invoked with the right parameters, this template produces output identical to that of the Cite templates, such as {{Cite book}} and {{Cite web}}. The default behavior sometimes differs from that of the Cite templates; for example, this template by default generates anchors for Harvard references whereas the Cite templates do not (although they can be made to do so), and this template by default uses commas to separate some fields that the Cite templates separate with periods (full stops).

The template should be inserted after punctuation, such as a period or comma.

All parameter names are lowercase.

Simple citation

This template gives the most commonly used attributes. You can copy the horizontal form or vertical form below and then add in extra attributes from the full list. Spacing and ordering is irrelevant.

{{Citation |last= |first= |year= |title= |publisher= |publication-place= |page= |url= |accessdate= }}

{{Citation | last = | first = | year = | title = | publisher = | publication-place = | page = | url = | accessdate = }}

• last: The author's surname or last name. Don't use with author.
• first: The author's first or given name(s).
• year: Year of authorship or publication. Mandatory for use with links from Template:Harvard citation, unless Template:Para specifies both month and year.
• title: Title of the work. Mandatory for web references.
• publisher: The name of the publisher. Omit terms such as Publishers, Co., Inc., Ltd., etc., but retain the words Books or Press.
  • publication-place (or place): The city of publication. If more than one town/city is listed on the title page, give the first one or the location of the publisher's head office.
• page: For use when one page is cited. Adds "p." before the page number. Do not use with pages.
• url: An url of an online location where the item can be found. If the url includes double quotes, these must be encoded as "%22".
  • accessdate: Date 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 | id = {{OL|7120924W}} }}

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 Template:Para generates an ID suitable for Harvard referencing templates such as {{harv}} as specified in the next section; this is the default for the {{citation}} template. If an empty Template:Para is given, no anchor is generated; this is the default for the Cite templates such as {{cite book}} and {{cite news}}. You can also specify the ID directly, using the Template:Para 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:

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 and the year of the cited source. For example, the markup "{{harv|Wright|Evans|1851|p=ix}}" generates the Harvard reference "Template:Harv", 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}}

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 <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. 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 Template:Para (or Template:Para), Template:Para, Template:Para, and Template:Para, and similarly for Template:Para etc. and for Template:Para 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 "Template:Para" with "Template:Para Template:Para", or add "Template:Para" to the {{citation}} invocation, or add the same ref parameter (say, "Template:Para") to both the {{citation}} and the {{harv}} invocations.

Similarly, the year is used, as specified by Template:Para. If no year is given, this template attempts to derive the year from Template:Para (or, if no date is given, from Template:Para) by applying the MediaWiki#time function. This heuristic works with many common date formats (American, International and ISO standard format YYYY-MM-DD as listed in WP:MOS), but may not work as expected with other formats, so when in doubt it may be safer to use Template:Para. Note that if only a year, say 2005, is known you must use Template:Para rather than Template:Para.

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:

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., "Template:Para" and "Template:Para", 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.
