Notes gathered at a single position
This method gathers the notes at a single position marked with the Reference text
 * Produces a reference mark linking to the reference text, provided that the tag  mentioned below is present on the page.
 * id Reference text
 * Ditto; also assigns a name to the reference text; the quotes are only needed if id contains spaces or special characters.
 * id
 * Produces a reference mark linking to a reference text defined before.
 * Inserts a list of reference texts, each preceded by a list of links to the positions in the page linking to the text; this applies for all texts inside  tags in the wikitext of the page.
 * Inserts a list of reference texts, each preceded by a list of links to the positions in the page linking to the text; this applies for all texts inside  tags in the wikitext of the page.

Multiple insertion of the same reference
mw:Extension:Cite:

References may be cited more than once using id. On the Edit page, this is placed at the first insertion point of citation:



This is placed at the second insertion point of citation:

This is placed at the third insertion point of citation:
 *   ..... and so forth for further insertion points

Single insertion of a reference
For the single insertion of a reference, the "name" parameter is not needed. On the Edit page, this is placed at the insertion point of citation:



To have the reference depend on a parameter, use e.g.:


 * giving

What is produced at the points of insertion
The '''


 * The first reference to Perry's Handbook.


 * The second reference to Perry's Handbook.


 * The third reference to Perry's Handbook.




 * }

Clicking on a numbered superscript takes you straight to the text of the corresponding footnote or reference.

Producing the reference or footnote list
The   tag is expanded to show the text of the footnotes or references against their corresponding numbers, like this:

For single citations, clicking on the caret ( ^ ) takes you to the point of citation in the main text.

For multiple citations, the links back to the main text can be distinguished in various ways, depending on MediaWiki:Cite references link many format and MediaWiki:Cite references link many format backlink labels: the default is to have double-numerical superscripts, e.g. 2.0, 2.1, .. for the second reference, while on Meta and the English Wikipedia we have letters instead of a second number (a instead of 0, b instead of 1, c instead of 2, etc.), and without repeating the reference number. Clicking on a link takes you to the corresponding citation in the main text.

You may also use a slightly different format if desired, like this:

== Example reference section ==

&lt;div class="references-small"> &lt;references /> &lt;/div>

to generate the example section on help:Footnotes/example 1.

Notes on the Cite.php method

 * Clicking on the blue superscript 1.0 causes the screen display to scroll back up to the point where the first reference to Perry's Handbook was inserted. Clicking on the blue superscript 1.1 causes the screen display to scroll back up to the point where the second reference to Perry's Handbook was inserted. Clicking on the blue superscript 1.2 causes the screen display to scroll back up to the point where the the third reference to Perry's Handbook was inserted ... and so forth.


 * Clicking on any vertical arrow ( ↑ ) that has no associated superscripts causes the screen display to scroll back up to the point where that single-use references was inserted.

Notes at independent positions
The systems below require a note tag with id for each note, but they allow the position of each footnote text to be chosen independently. For example, footnotes in a table or section can be put at the bottom of the table or section.

Ref and note template
System using and :

A disadvantage of this method is that references to the same note appear with different numbers, and that from the note there is only a link back to the first reference to it, e.g.:

.

The latter disadvantage is overcome by using multiple ref/note pairs, each with a different name, e.g.:


 * Not many words in the English language use two consecutive "u"s. There is one word that is both rather empty and also sucks.


 * 1)    The word is vacuum.

However, this method has advantage over &lt;ref> in that, it can split the footnotes into each section, while &lt;references/> does put all footnotes in one place, and can't be split.
