Editing Template:Harvard citation documentation (section)

===Parameters===

====Author(s) and year====
The first four author surnames (or all authors if fewer than four; use the values from {{para|last''N''}} or {{para|author''N''}}{{hairspace}}) are required, followed by the year of publication (from {{para|year}} or {{para|date}}). Authors past the fourth must be omitted or an error will result.

The [[#Possible issues|possible issues]] section below describes workarounds for various common problems, such as [[#Large number of authors|large number of authors]], [[#No author name in citation template|no author name]], [[#More than one work in a year|multiple works in the same year]], [[#More than one author with the same last name|multiple authors with same last name]] and others.

====Location in the source text====
The optional parameters {{para|p}}, {{para|pp}} and {{para|loc}} can be used to indicate the location in the source, such as page numbers. For single pages, use {{para|p}}; for multiple pages (such as ranges), use {{para|pp}}. Use of {{para|p}} for multiple pages or {{para|pp}} for single pages can cause [[Help:Cite errors/Cite error references duplicate key|cite errors]]. {{para|loc}} can be used to specify a location in the source in another way, such as section numbers or chapters. It can also be combined with {{para|p}} or {{para|pp}}. The parameters {{para|page}} and {{para|pages}} exist as aliases for {{para|p}} and {{para|pp}}, respectively.

====Additional text====
The optional parameter {{para|postscript}} or {{para|ps}} can be used to change the text which appears at the end of the note in the reference list. (See [[#Additional comments or quotes|§ Adding additional comments or quotes]] and [[#No closing period|§ No closing period]], below.) Subsequent invocations of {{tl2|sfn}} with the same author, year, page, and location values but a different value for this parameter with produce a cite error about multiple definition.

====Hard-coded link names====
''Not available in {{tl2|sfn}} and similar templates.''

The optional parameter {{para|ref}} is used to create an unusually named link from the short citation to the full citation. This parameter is usually not necessary, and it is more common to use {{tl2|sfnRef}} or {{tl2|harvid}} in the reference section. If you specify {{para|ref|none}}, no hyperlink is created. However, if one does not want the link, it is always possible to simply use plain text instead of the template. The parameter {{para|Ref}} is an alias for {{para|ref}}.
