For hatting an unproductive discussion, see Template:Hat.

Hatnotes are short notes placed at the top of an article (hence the name "hat"). Hatnotes help readers locate a different article they might be seeking. Readers may have arrived at the article containing the hatnote because they were redirected, because the sought article uses a more specific, disambiguated title, or because the sought article and the article with the hatnote have similar names. Hatnotes provide links to the possibly sought article or to a disambiguation page.

For more information about methods of disambiguating articles, see Tractor & Construction Plant Wiki:Disambiguation.

Format

In most cases, hatnotes should be created using a standard disambiguation template (as illustrated below). This permits the form and structure of hatnotes to be changed uniformly across the encyclopedia as needed.

Current Tractor Wiki style is to italicise and indent each note, without a bullet before the item. A horizontal dividing line should not be placed under a note, nor after the final item in a list.

Summarize or not?

Shortcut:
WP:HNS

Some hatnote disambiguation templates include a brief summary of the present article's topic; others do not. For instance, in the article Honey, one might use the template {{about|the insect-produced fluid}} to produce:

This article is about the insect-produced fluid. For other uses of the term, see Honey (disambiguation).

Alternatively, one might use {{other uses|{{{2}}}}} to produce:

For other uses, see Honey (disambiguation).

Either of these two styles is acceptable. The choice of style in a given article is based on editors' preference, and what is likely to be clearer and easier for the reader. Where an article already has a hatnote in one of these styles, editors should not change it to the other style without good reason or broad consensus.

Placement

See also: Tractor & Construction Plant Wiki:Manual of Style (lead section)#Elements of the lead
Shortcut:
WP:HNP

Hatnotes are placed at the very top of the article, before any other items such as images, navigational templates and maintenance templates (like the "cleanup", "unreferenced", and "POV" templates). Text-only browsers and screen readers present the page sequentially. If a reader has reached the wrong page, they typically want to know that first.

Examples of proper use

Two articles with similar titles

Shortcut:
WP:SIMILAR
This article is about the village in England. For H. P. Lovecraft's fictional town, see Dunwich (Lovecraft).

Dunwich (pronounced /ˈdʌnɪtʃ/ DUN-ich) is a town in the county of Suffolk in England, the remnant of what was once a prosperous seaport and centre of the wool trade during the early middle ages, with a natural harbour formed by the mouths of the River Blyth...

When two articles share the same title, except that one is disambiguated and the other not, the undisambiguated article should include a hatnote with a link to the other article. It is not necessary to create a separate disambiguation page. {{about}} may be used for this. In this case the parameterisation was {{about|the village in England}}.

Linking to a disambiguation page

For other uses, see Monolith (disambiguation).

A monolith is a monument or natural feature such as a mountain, consisting of a single massive stone or rock. Erosion usually exposes these formations...

When a term has a primary meaning and two or more additional meanings, the hatnote on the primary topic page should link to a disambiguation page. {{other uses}} may be used for this.

In many cases the hatnote also includes a brief description of the subject of the present article, for readers' convenience:

This article is about the maze-like labyrinth from Greek mythology. For other uses, see Labyrinth (disambiguation).

In Greek mythology, the Labyrinth was an elaborate maze-like structure constructed for King Minos of Crete and designed by the legendary artificer Daedalus to hold the Minotaur...

The template {{about}} may be used for this. In this case the parameterization was {{about|the mazelike labyrinth from Greek mythology}}.

Ambiguous term that redirects to an unambiguously named article

{{redirect}}, or a related template, can be used when an ambiguous title is redirected to an unambiguous title or a primary topic article:

Johann Sebastian Bach


From Wikipedia, the free encyclopedia
(Redirected from Bach)

"Bach" redirects here. For other uses, see Bach (disambiguation).

Johann Sebastian Bach (German pronunciation: [joˈhan/ˈjoːhan zeˈbastjan ˈbax]; March 21, 1685 O.S.July 28, 1750 N.S.) was a prolific German composer...

Examples of improper use

Trivial information, dictionary definitions, and slang

When notes feature a trivial detail or use of a term, or links to overly specific and tendentious material, they are unwarranted.

During a siege, to invest a town or fortress means to surround it with a contravallation and a circumvallation.

Investment is a term with several closely related meanings in finance and economics. It refers to the accumulation of some kind of asset in hopes of getting a future return from it...

In this case, there is no direct disambiguation, and the note listed is bound to be uninteresting to most readers. The proper disambiguation simply links to a separate Invest (disambiguation) page.

Legitimate information about the topic

A previous version of the Aisha article showed:

Ayesha is sometimes used as a woman's name. Once popular only among Muslims, it was briefly popular among English-speakers after it appeared in the book She by Rider Haggard.

Aisha or Ayesha (Arabic عائشه `ā'isha = "she who lives") was a wife of the Islamic prophet Muhammad...

This is a typical and highly improper misuse of disambiguating hatnotes. Instead, the information belongs in the body of the article, or in the articles about the book, or in a separate article about names, or all three places. Hatnotes are meant to reduce confusion and direct readers to another article they might have been looking for, not for information about the subject of the article itself.

Shortcut:
WP:RELATED

Linking to articles that are related to the topic

Disambiguation hatnotes are sometimes improperly used to link to an article about a related topic, or a specific aspect of the general topic.

This article is about the scientific study of extraterrestrial life; for treatment in popular culture, see Extraterrestrial life in popular culture.

Extraterrestrial life is life that may exist and originate outside the planet Earth. Its existence is currently hypothetical: there is as yet no evidence of extraterrestrial life that has been widely accepted by scientists...

Instead of using a disambiguation hatnote, it is better to summarize Extraterrestrial life in popular culture under a subsection of Extraterrestrial life in conjunction with the {{main}} template. Alternatively, it could be linked to in the See also section.

Shortcut:
WP:NAMB

Disambiguating article names that are not ambiguous

Tree (set theory)


From Tractor Wiki, the free tractor & classic vehicle encyclopedia

For other uses, see Tree (disambiguation).

In set theory, a tree is a partially ordered set (poset) in which there is a single unique minimal element (called the root) and in which the set of elements less than a given element is well ordered...

Here, the hatnote is inappropriate because a reader who is following links within Wiki or using Wiki's own search engine would not have ended up at tree (set theory) if one were looking for other types of trees, since tree does not redirect there.

However, a hatnote may still be appropriate when even a more specific name is still ambiguous. For example, Matt Smith (comics) might still be confused for the comics illustrator Matt Smith (illustrator).

A hatnote may also be appropriate in an unambiguously named article when an ambiguous term redirects to it, as explained in the "Proper uses" section above.

Extraneous links

Shortcut:
WP:HATEXTRA

One should not link terms other than the desired target in the hatnote. For example:

WTIX (980 AM) is a radio station broadcasting a Sports radio format.

In this case, the link to New Orleans, Louisiana in the hatnote is inappropriate. Only the possible other destination (WIST (AM)) should be linked.

External links

A previous version of the wikipedia:Hurricane Katrina article contained:

If you are trying to locate someone missing in Hurricane Katrina, or register yourself as found, you can use the site www.disastersearch.org [1]

Hurricane Katrina, which made landfall near New Orleans, Louisiana, on August 29, 2005, was one of the most destructive and expensive tropical cyclones to hit the United States...

The use of external help links in Wikipedia, though noble, cannot reasonably be maintained. In special cases, a link to an "External links" section with several links may be appropriate, but POV favoritism can be obstructive. In this case, the hatnote was removed entirely.

Non-existent articles

Shortcut:
WP:NOARTICLE

Hatnotes should not be used for articles that do not exist since the notes are intended to point the user to another article they may have intended to find. The exception is if one intends to create the linked article immediately. In that case, consider creating the new article first, before saving the addition of the hatnote.

Hatnote templates

Shortcut:
T:HAT

For a summary page on how to use these templates, see the example page here. For the full editing guideline on hatnotes, see project:Hatnote.

Generic

{{Dablink|For other senses of this term, see etc...}}

Other uses

"This page is about ... For other uses ..."

{{About}} is the main template for noting other uses.

Note. When used in main namespace, the word "page" in the following hatnotes is replaced by "article".

  • {{About|USE1}}
  • {{About|USE1||PAGE2}} (When the disambiguation page has a different name — Note the empty second parameter) →
  • {{About|USE1|USE2|PAGE2}} (When there is only one other use) →
  • {{About|USE1|USE2|PAGE2|and|PAGE3}} (Two pages for USE2) →
  • {{About|USE1|USE2|PAGE2|USE3|PAGE3|USE4|PAGE4|USE5|PAGE5}} (When there are up to five other uses — You should generally create a disambiguation page at this point) →
  • {{About|USE1|USE2|PAGE2|USE3|PAGE3|other uses}} (When there are several standard other uses and also a disambiguation page with default name — Note that the last page name is not specified) →
  • {{About|USE1|USE2|PAGE2|USE3|PAGE3|other uses|PAGE4}} (When there are several standard other uses and also a disambiguation page with non-default name) →
  • {{About|USE1|USE2|PAGE2|USE3|PAGE3|other uses|PAGE4|and}}
  • {{About||USE2|PAGE2|USE3|PAGE3|other uses}} (When you don't need to state the focus of this article/page — Note the empty first parameter) →
  • {{About|||PAGE1|and|PAGE2}}
Note: {{for||PAGE1|PAGE2}} produces the same result.
  • {{This|USE}}
Note: {{About|USE}} produces the same result: →
  • {{This|USE|PAGE1}}
Note: {{About|USE||PAGE1}} (with one empty parameter) produces the same result: →
  • {{Other uses-section|USE}} (disambiguous) →
Note: this hatnote says "section", instead of "article" or "page".

"For other uses, see ..."

When such a wordy hatnote as {{About}} is not needed, {{Other uses}} is often useful.

  • {{Other uses}} (disambiguous) →
  • {{Other uses|PAGE1}}
Variations

There are, historically, a whole family of "other uses" templates for specific cases. {{About}} is the standard hatnote for "other uses" and many of them can be specified using the {{About}} template. However, the individual templates may be easier to use in certain contexts.

Here are the variations and (when appropriate) the equivalents using the {{About}}, {{Other uses}} or {{For}} templates.

  • {{Other uses2|PAGE1}} (disambiguous) →
Note: adds "(disambiguation)" to whatever is input as the PAGE1.
Note: {{Other uses|PAGE1 (disambiguation)}} produces the same result.
  • {{Two other uses|USE1|USE2|PAGE2}}
Note: same as {{about}}, except it forces a second use to be noted if unspecified by parameters.
  • {{Two other uses|USE1|USE2|PAGE2|USE3|PAGE3}}
  • {{Three other uses|USE1|USE2|PAGE2|USE3|PAGE3}}
  • {{Three other uses||USE2|PAGE2|USE3|PAGE3}}
  • {{Three other uses|USE1|USE2|PAGE2|USE3|PAGE3|USE4|PAGE4}}

"For ..., see ..."

{{For}} can be used instead of {{About}} so as not to display: This page is about USE1. but still specify a specific other use. This effect can also be achieved by using an empty first parameter in {{About}} as in:

For example: {{for|OTHER TOPIC|PAGE1}} is the same as {{About||OTHER TOPIC|PAGE1}} (note the empty first parameter).

However, it is somewhat clearer when using the {{For}} template, since the word "about" does not appear in the statement.

  • {{For|OTHER TOPIC}} (disambiguous) →
For OTHER TOPIC, see Hatnote (disambiguation).
  • {{For|OTHER TOPIC|PAGE1}}
For OTHER TOPIC, see PAGE1.
  • {{For|OTHER TOPIC|PAGE1|PAGE2}}
For OTHER TOPIC, see PAGE1 and PAGE2.
  • {{For|OTHER TOPIC|PAGE1|PAGE2|PAGE3}}
For OTHER TOPIC, see PAGE1 and PAGE2.
  • {{For||PAGE1|PAGE2}}
For , see PAGE1 and PAGE2.
Variations

As with {{Other uses}}, there are a whole family of "for" templates.

  • {{For2|OTHER TOPIC|CUSTOM TEXT}}
  • {{For example|Pagename|Piped link name}}

"For other uses of ..., see ..."

"For more details on ..., see ..."

{{Details}} is used to make summary style explicit. To be used in a section for which there is also a separate article on the subject.

{{Details3}} allows any text to links:

"Further information: ..."

  • {{See|OTHER TOPIC}}

Example with multiple parameters

  • {{See|Diesel|Petrol|LPG|hydrogen fuel}}
  • {{Further|[[Article 1]], [[Article 2]], and [[Article Something#3|Article 3]]}}
Further information: Article 1, Article 2, and Article 3

This template takes a single parameter of any length.

"See also ..."

See also: OTHER TOPIC
Note: use when OTHER TOPIC is related to that of the current article and already contains a self-explanatory parenthetical.
  • {{See also2|OTHER TOPIC and other text}}

"... redirects here. For other uses, see ..."

  • {{Redirect|REDIRECT}} (disambiguous) →
  • {{Redirect|REDIRECT||PAGE1}}
  • {{Redirect|REDIRECT|USE1|PAGE1}}
  • {{Redirect|REDIRECT|USE1|PAGE1|USE2|PAGE2}}
  • {{Redirect|REDIRECT|USE1|PAGE1|USE2|PAGE2|USE3|PAGE3}}
  • {{Redirect|REDIRECT|USE1|PAGE1|and|PAGE2}}
  • {{Redirect|REDIRECT|USE1|PAGE1|USE2|PAGE2|and|PAGE3}}
Variations
  • {{Redirect-acronym|TERM|PAGE}}
  • {{Redirect2|REDIRECT1|REDIRECT2}} (disambiguous) →
  • {{Redirect2|REDIRECT1|REDIRECT2|USE|PAGE1}}
  • {{Redirect2|REDIRECT1|REDIRECT2|USE1|PAGE1|USE2|PAGE2}}
  • {{Redirect2|REDIRECT1|REDIRECT2|USE1|PAGE1|USE2|PAGE2|USE3|PAGE3}}
  • {{Redirect3|REDIRECT|TEXT}}
  • {{Redirect4|REDIRECT1|REDIRECT2}} (disambiguous) →
  • {{Redirect6|REDIRECT|USE1|PAGE1}} (disambiguous) →
  • {{Redirect7|"REDIRECT1", "REDIRECT2", and "REDIRECT3"|USE1|PAGE1|USE2|PAGE2}}
Note: If the number of pages redirecting to the target page is two, {{Redirect2}} can be used instead. If the number is three and there are three corresponding disambiguation pages, {{Redirect10}} can be used.
  • {{Redirect10|REDIRECT1|REDIRECT2|REDIRECT3}} (disambiguous) →

Other people

  • {{Other persons}} (disambiguous) →
  • {{Other persons|NAME}} (disambiguous) →
  • {{Other persons|NAME|PAGE}}
  • {{Other people2|PAGE}}
  • {{Other people3}} (disambiguous) →
Note: same as {{About}} except uses "other people" instead of "other uses" if only 1 parameter is used
  • {{Other people3|PERSON1}} (disambiguous) →
  • {{Other people3|PERSON1|PERSON2}} (disambiguous) →
  • {{Other people3|PERSON1|PERSON2|PAGE2}}
  • {{Other people3|PERSON1||PAGE2}}
  • {{Other people4|NAME|PAGE|named=titled}}
  • {{Other people5|NAME1|NAME2|NAME3|NAME4}}

Wikipedia self-reference

Note: used for hatnotes that don't make sense on mirrors of Wikipedia, such as linking an article from the main namespace to the Wikipedia namespace. (See: Manual of Style (self-references to avoid) for more details).

Categories

Category-specific templates produce bold category names.

  • {{Category see also|THIS|THAT|THE OTHER}}See also categories: THIS, THAT, and THE OTHER

This is a template for linking categories horizontally. Horizontal linkage is often the right solution when vertical linkage (i.e. as sub-category and parent category) is not appropriate. In most cases, this template should be used on both categories to create reciprocal linkage between the two categories.

See also the preceding Category:OTHER TOPIC.
  • {{CatSucceeding|OTHER TOPIC}}
  • {{Category pair|TOPIC1|TOPIC2}}
Hatnote is often contrasted with OTHERCAT.
Hatnote are very often contrasted with OTHERCAT.

Notes

Do not use subst: with these templates, as that will prevent:

  1. propagating changes as the template is modified; and the
  2. What links here (WLH) listing.

These templates are used in thousands of articles; therefore, changing the syntax could break thousands of articles. If you wish to create or edit a disambiguation or redirection template, first ask yourself the following questions:

  1. Is there already a template that will do this job? Since many disambiguation and redirection templates have already been created, first check: Category:Disambiguation and redirection templates.
  2. Do I really need a new template for this? Will it likely be used on any other articles or should I just use {{dablink}} instead? Before creating a new template, see: Template namespace guideline.
  3. If I change the parameters around on an existing template, do I know what the result will be? Will it break existing uses of the template and if so, can I fix all of the errors? Before making any changes, see: Template sandbox and test cases.
