Wikipedia:Organizing disambiguation pages by subject area

On large disambiguation pages, organizing by subject area helps readers find the page they want. Readers should be able to find their target article in one pass – narrowing down from sections to subsections to entries – without needing to re-read anything. Three principles enable that goal. This supplement also includes suggested headings. Guidance for individual entries is at Wikipedia:Manual of Style/Disambiguation pages.

Principles

1. Clearly defined subject areas

The title of each section must make it clear what kinds of entries it contains, and all entries that fit in that section should be there. Also:

• Choose subject areas that don't overlap. If overlap can't be avoided (e.g., record labels that fit under both "Music" and "Businesses"):
  • For one or two items that fit in multiple sections: duplicate these entries in all appropriate sections.
  • For several items (or a subsection): put in only one section, and put a hatnote at the top of the other appropriate sections, e.g.: {{for|<topic>|#<Section>}} or {{see also|#<Section>}} .
• Only combine topics that are closely related. "Biology and medicine" is fine; "Cosmology and medicine" is not. "Other uses" is the exception.
• Always separate fictional entities from real ones.

2. Moderate section size

It's easiest for readers to find the topic they're looking for when the sections are moderately sized:

• Sections with more than ten to twelve entries should usually be divided, if practical. Use judgment based on the particular page.
• Sections with only one or two entries should usually be combined, often in an "Other uses" section. Sections with only one entry should almost always be combined.

3. "Other uses" below

Entries that are not fully categorized belong in an "Other uses" section at the end of the page or section (but before any "See also" section). The space above the first section (or above the first subsection in a section) should not have any entries ("floaters"), except for:

• At most one primary topic, if there is one, at the top of the page.
• A few significantly more common meanings, if they exist – and these should be repeated in the appropriate topic sections.

Also:

• If there are four or more headings, always put {{TOC right}} above the first heading.
• Use ==Wiki headings==, not bold text or semicolon markup, for headings (see WP:PSEUDOHEAD).
• Use the "See also" section for entries whose titles are related to, but not strictly ambiguous with, the page title.
• Typically order sections alphabetically. (This is the easiest scheme to recognize – relative importance is usually too subjective.)

Example scheme

This scheme, or any part of it, may be used to organize disambiguation pages. Braces ("{}") suggest alternative terms, which may be split up and recombined in keeping with the principles above. Common pitfalls that may make dab pages harder to navigate are marked in red.

NOTE! These headings are an example only; most disambiguation pages will only use a few of these headings. They should be liberally modified, supplemented, and promoted or demoted to different header levels to best suit each particular page. Disambiguation pages are enormously varied, and another scheme may better suit a given page. (Note, though, that schemes not based on subject area, such as grouping entries by their formatting, or separating out acronyms or initialisms, can be confusing for readers and are usually avoided.)

Remember to remove visible braces ("{ }") and pipes ("|") before saving a dab page.

[Title] may refer to:

{Arts|entertainment|media} [Avoid the word "culture" in this heading; it is too vague.]

[Sports-related entries are typically listed in "People", "Organizations", and/or "Sport", not here.]

[Technologies used in media and entertainment are typically listed in "Science and technology", not here.]

[If people or organizations in the arts are listed elsewhere, note this in a hatnote, e.g.: For people in arts and entertainment, see § People.]

[It may be useful to separate titled works (i.e., proper names) from generic/common terms.]

Fictional {characters|elements}

[Useful for entities that appear in multiple types of media; otherwise sort by medium as below.]

{Film|radio|television|theater}

Gaming

{Literature|writing} [Avoid the word "Print", which excludes digital written media.]

{Books|novels}

{Comics|magazines|newspapers|periodicals}

{Short stories|poems}

Music

{Artists|bands|groups|performers}

{Albums|symphonies|compositions}

{Songs|recordings|tracks}

Other media

{Businesses|organizations}

{Government|military|politics}

[Break down geographically if needed]

{Schools|Universities}

[Break down geographically or by academic level if needed]

Sports {teams|organizations}

[If listed in a separate "Sport" section, note this in a hatnote]

Other {businesses|organizations}

[Break down by industry if needed]

{Economics|finance|law}

[For topics in economic science, a subsection of "Science" may be more appropriate.]

Language

[Do not list dictionary definitions; these should be handled with the {{wiktionary}} template.]

[For topics in linguistic science, a subsection of "Science" may be more appropriate.]

People

[People with the page title as part of their common name should typically be listed on an Anthroponymy page, such as Bob (given name), not a disambiguation page, unless there are only a small number of such people.]

[List groups of people (such as ethnic groups) and titles shared by several people separately from individuals.]

In {academia|science}

In {arts|entertainment|media}

[Break down by type of media if needed, though this may cause overlap with an "Arts and media" section]

In business

In {government|military|politics}

In religion

Sportspeople

Other people

Places

[Break down geographically, or separate into buildings, administrative entities (like cities and states), and natural formations, if needed]

{Religion|philosophy|mythology}

[If people in these fields are listed in a separate "People" section, note this in a hatnote.]

{Science|technology|mathematics} [Avoid separating these topics, as they often have significant overlap.]

[If people in these fields are listed in a separate "People" section, note this in a hatnote.]

Natural sciences

{Astronomy|cosmology}

{Biology|medicine|organic chemistry}

{Chemistry|physics}

{Geology|Earth science}

{Psychology|sociology}

{Computing|electronics|telecommunication}

[Games and digital content belong under "Arts and media", not here, unless they deal with these topics specifically.]

Mathematics

[Some consider mathematics to be a science, some don't. If there are math topics here, it is advisable to include "mathematics" in the parent section title.]

{Military technology|weapons}

[May overlap with "Computing" or "Transportation" subsections.]

{Transportation|vehicles}

[If transportation topics are listed in a separate section, note this in a hatnote.]

Other uses in {science|technology|mathematics}

Sports

[Caution: This section may have significant overlap with "People" and "Organizations" sections; consider using them instead.]

[Break down by sport, or separate into amateur, professional, and school sports, if needed]

Transportation

[Caution: This section may have significant overlap with "Science and technology", "Businesses and organizations", and "Places" sections; consider using them instead.]

{Airports|facilities|stations}

{Transit systems|Transportation companies}

Vehicles

[Often used for individual vessels, with types of vehicles listed under "Science and technology" instead]

{Air|space}

{Land|rail}

{Maritime|sea|ships}

Other uses

[Ambiguous entries that do not fit into another section. Entries that fit in another section, but not in any of its subsections, should be placed in an "Other uses in [topic]" subsection there.]

See also

[Entries that are related to, but not ambiguous with, the page title, that might reasonably help readers find what they are looking for, such as: search templates like {{lookfrom}}, {{intitle}}, and {{canned search}}; misspellings; and similar words. Use judgment; do not include every page that contains the ambiguous term.]
