Stamps Wiki:Hatnote

Hatnotes are short notes placed at the very top of an article or a [Stamps Wiki:Section|section]], like a hat is placed on the very top of a head. (See the note in italics immediately preceding the box above.) Their purpose is to help readers locate a different article if the one they are at is not the one they're looking for. Readers may have arrived at the article containing the hatnote because:
 * They were redirected.
 * They may be seeking an article that uses a more specific, disambiguated title.
 * They may be seeking an article with a similar name to or that otherwise might be confused with the article with the hatnote.

Hatnotes provide links to the possibly sought article or to a disambiguation page.

The five basic rules of hatnotes are:


 * 1) Link directly to other articles; do not pipe non-disambiguation links. Linking to redirects is typically not preferred, although of course exceptions can occur. Links to disambiguation pages should always end in "(disambiguation)", even when that version of the title is a redirect.
 * 2) Keep explanations to a minimum; explain vital information only, trusting instead in the article lead to clarify things for the reader.
 * 3) Mention other topics and articles only if there is a reasonable possibility of a reader arriving at the article either by mistake or with another topic in mind.
 * 4) However, if a notable topic X is commonly referred to as "Foo", but the article "Foo" is not about X, there must be a hatnote linking to the article on X or linking to a disambiguation page that contains a link to the article on X.
 * 5) Ideally, limit hatnotes to just one at the top of the page or section. Multiple hatnotes may be appropriate when they serve different purposes, such as disambiguating topics with similar names and explaining redirects.

For more information about methods of disambiguating articles, see Stamps Wiki:Disambiguation.

Placement
Place hatnotes at the top of the article or section. When used at the top of an article, hatnotes go immediately below a short description template, but strictly above anything else including protection icons or maintenance tags. Text-based web browsers and screen readers present the page sequentially. If a reader has reached the wrong page, they should find that out first.

In the Stamps Wiki iOS app, there is a known bug whereby hatnotes fail to appear anywhere on the page.

Format
In most cases, hatnotes should be created using a standard hatnote template as illustrated in below. This permits the form and structure of hatnotes to be changed uniformly across the encyclopedia as needed and the templates to be excluded in print.

Current style on the English Stamps Wiki is to italicize and to indent each note, without a bullet before the item. A horizontal dividing line should not be placed either under a note or after the final item in a list. Links to articles should follow the naming conventions for capitalization – typically sentence case, not all lower case.

When determining the content of the hatnote, keep in mind that it forms part of the user interface rather than the article content. Two applicable user interface design principles are clarity and conciseness. The hatnote should not overload the user with extraneous information, and the content should be imparted quickly and accurately. These design goals are conveyed succinctly in the principle less is more.

Length and number
As hatnotes separate the reader from the content they are looking for, hatnotes should generally be as concise as possible. Long explanations are generally discouraged; the article's lead text, not the hatnote, should explain what the article is about. In almost all cases, the hatnote is intended only to direct readers to other articles in case they were actually looking for something they will not find in the article containing the hatnote.

If a disambiguation page exists for a given term, then linking to it should be enough. For example, if the article is X then its hatnote will link to X (disambiguation); it should not have entries for other topics known as X, like X (novel) or X (charge), because they are already listed in the disambiguation page. However, such an article may be linked if it could be expected by a significant number of readers to be at the title in question.

There should be as few hatnotes as possible. One single hatnote, which can accommodate several links, is greatly preferable to two or more. Multiple hatnotes may however be appropriate when each serves a different purpose, such as disambiguating the title or distinguishing similar terms.

Summarize or not?
Some hatnote disambiguation templates include a brief summary of the present article's topic; others do not have a summary. For instance, in the article Honey, one might use the template to produce:

Alternatively, one might use to produce:

Either of these two styles is acceptable. The choice of style in a given article is based on editors' preferences and on what is likely to be clearer and easier for the reader. (In this particular instance, most English speakers will know what honey is, and the second, more concise hatnote is preferable.) Where an article already has a hatnote in one of these styles, editors should not change it to the other style without good reason.

Two articles with similar titles


Dunwich 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 parameterization was.

Terms that can cause confusion with another topic


Perl is a family of high-level, general-purpose], interpreted, dynamic programming languages. ...

Distinguish or a related template can be used when there can be confusion with a similar term. They are typically used when readers have misspelled their desired title, and the error would be apparent by simply displaying the alternative term without further explanation. These hatnotes should only be used when the ambiguity exists for a significant portion of the readership.

However, they are not suitable when the difference is not readily apparent without additional details. In those cases, use about or other uses instead, as the differences in the suggested article are explained upfront without requiring the reader to click through and differentiate the terms on their own.

Linking to a disambiguation page
 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: 

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.

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

(Redirected from )

Johann Sebastian Bach (March 21, 1685 O.S. – July 28, 1750 N.S.) was a prolific Germany|German composer. ...

Hatnotes above maintenance tags
Always place a hatnote above maintenance tags, but below short description templates. See above for specific details regarding the placement of hatnotes. 

The Giver is a 1993 American young-adult dystopian novel by Lois Lowry. It is set in a society which at first appears as utopian but is later revealed to be a dystopian one as the story progresses. The novel follows a boy named Jonas. ...

Hatnotes with italics in the links


Caprona agama, the spotted angle, is a butterfly belonging to the family Hesperiidae. ...

The italics are cancelled by the parameterization:

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.

A previous version of the article Investment showed:



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: 

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

This is a typical but improper use 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.

Linking to articles that are related to the topic
Disambiguation hatnotes are intended to link to separate topics that could be referred to by the same title. They are not intended to link to topics that are simply related to each other, or to a specific aspect of a general topic:



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 in such cases, it is better to summarize the topic Extraterrestrial life in popular culture under a subsection of Extraterrestrial life in conjunction with the main template.

This guideline does not discourage the use of disambiguation hatnotes in a situation where separate topics are related, but could nonetheless be referred to by the same title and would thus qualify for disambiguation, such as a book and its film adaptation.

Disambiguating article names that are not ambiguous
It is usually preferable not to have a hatnote when the name of the article is not ambiguous.  Water (Wu Xing)

Water, is the low point of the matter, or the matter's dying or hiding stage. Water is the fifth stage of Wu Xing. ...

Here, the hatnote can be removed. A reader who is following links within Wikipedia is unlikely to end up at Water (Wu Xing) if they were looking for other meanings of water, since water does not redirect there.

A hatnote may still be appropriate when even a more specific name is still ambiguous. For example, Tree (set theory) might still be confused with Tree (descriptive set theory).

The presence or absence of hatnotes in articles with disambiguated titles has been a contentious issue, and this guideline doesn't prescribe one way or the other. There are cases where some editors strongly believe that such hatnotes should be included, such as the various articles about treaties called Treaty of Paris.

A hatnote may be appropriate in an unambiguously named article when an ambiguous term redirects to it, as explained in above.

Extraneous links
Each additional link in the hatnote besides the ambiguous or confusable topic(s) makes it more difficult to find the desired target. 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 leads to an article that is not ambiguous with the title. Linking only to the possible other destination (WIST (AM)) makes it easier to find the link.

Non-existent articles
Hatnotes should not contain red links to non-existent articles since hatnotes are intended to help users navigate 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.

Generic hatnote
allows general text to be shown in hatnote format. It is appropriate when none of the other specific templates listed below includes the combination of parameters needed, or to combine several of them in a single hatnote.




 * (a generic template for self-references to Wikipedia material)

Other uses of the same title ("For ..., see ...")
Per WP:NAMB, it is usually preferable not to have a hatnote when the name of the article is not ambiguous.

"This page is about ... For other uses ..."
is the main template for noting other uses.

Note: When used in main namespace (aka mainspace), the word "page" in the following hatnotes is replaced by "article".


 * (When the disambiguation page has a different name – Note the empty second parameter) →
 * (When there is only one other use) →
 * (Two pages for USE2) →
 * (Using the ! magic word to give the link a different title) →
 * (When there are several standard other uses and also a disambiguation page with default name – Note that the last page name is not specified) →
 * (When there are several standard other uses and also a disambiguation page with non-default name) →
 * (When you don't need to state the focus of this article/page – Note the empty first parameter) →
 * Note: produces the same result.

 * Note: this hatnote says "section", instead of "article" or "page".

"This page is about ... It is not to be confused with ..."
is a template for noting other uses when there could be confusion with another topic.



"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: is the same as  (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.




 * Variations
 * As with Other uses, there is a whole family of "for" templates. For2 allows custom text, such as quotation marks or a link from part of the "CUSTOM TEXT", but does not supply automatic wikilinking


 * → (note how CUSTOM TEXT isn't bluelinked)
 * It also supports up to three topics:



"For other uses, see ..."
When such a wordy hatnote as About is not needed, Other uses is often useful.




 * 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.


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

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



 * Variations:
 * For two sources:
 * For three or more sources:
 * To specify the text following "redirects here.":

Family names
Family names can also be clarified using inline footnotes, such as with Efn Chinese name.

"Main article: ..."
is used to make summary style explicit, when used in a summary section for which there is also a separate article on the subject:

"Further information: ..."
can supplement in summary sections, or can indicate more details in nonsummary sections:

"See also ..."
can be used at the head of a section.
 * Note: use only when OTHER TOPIC PAGE is related to current article and contains a self-explanatory parenthetical.

For category pages
Category-specific templates: 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.



What to do before editing or creating a template
These templates are used in literally 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:Hatnote 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 Hatnote instead? Before creating a new template, see the 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.
