Moving non-conventionally categorized pages to another category name (see <span class="nowrap">{{</span><a href="/wiki/Template:Category_redirect" title="Template:Category redirect">Category redirect</a><span class="nowrap">}}</span>) imposes an additional overhead – an edit for <i>each</i> article and subcategory. Also, try to avoid names that are too long or too short. Short, straight-forward names are preferred for categories, though it may be necessary at times to deviate from this principle for <a href="/wiki/Wikipedia:PRECISION" class="mw-redirect" title="Wikipedia:PRECISION">clarity</a> or <a href="/wiki/Wikipedia:TITLEDAB" class="mw-redirect" title="Wikipedia:TITLEDAB">disambiguation</a>. </p> <div class="mw-heading mw-heading3"><h3 id="General_conventions" data-mw-thread-id="h-General_conventions-Naming_conventions"><span data-mw-comment-start="" id="h-General_conventions-Naming_conventions"></span>General conventions<span data-mw-comment-end="h-General_conventions-Naming_conventions"></span></h3></div> <ul><li>Names of <a href="/wiki/Wikipedia:TOPICCAT" class="mw-redirect" title="Wikipedia:TOPICCAT">topic categories</a> should be singular, normally corresponding to the name of a Wikipedia article. Examples: "<a href="/wiki/Category:Law" title="Category:Law">Law</a>", "<a href="/wiki/Category:France" title="Category:France">France</a>", "<a href="/wiki/Category:Hillary_Clinton" title="Category:Hillary Clinton">Hillary Clinton</a>".</li> <li>Names of <a href="/wiki/Wikipedia:SETCAT" class="mw-redirect" title="Wikipedia:SETCAT">set categories</a> should be plural.

For example, <a href="/wiki/Category:Opera" title="Category:Opera">Opera</a> is a topic category (containing all articles relating to the topic), while <a href="/wiki/Category:Operas" title="Category:Operas">Operas</a> is a set category (containing articles about specific operas). Be careful to choose the right one when categorizing articles.</li> <li>Do not write <a class="mw-selflink-fragment" href="#Category_tree_organization">the category structure</a> in names. Example: "<a href="/wiki/Category:Monarchs" title="Category:Monarchs">Monarchs</a>", not "People – Monarchs". This includes creating categories that are subpages of other categories.</li> <li>Choose category names that can stand alone, independent of the way a category is connected to other categories. Example: "<a href="/wiki/Category:Geography_terminology_stubs" title="Category:Geography terminology stubs">Geography terminology stubs</a>", not "Terminology" (a subcategory of "<a href="/wiki/Category:Geography_stubs" title="Category:Geography stubs">Geography stubs</a>").</li></ul> <div class="mw-heading mw-heading3"><h3 id="Categories_for_articles" data-mw-thread-id="h-Categories_for_articles-Naming_conventions"><span data-mw-comment-start="" id="h-Categories_for_articles-Naming_conventions"></span>Categories for articles<span data-mw-comment-end="h-Categories_for_articles-Naming_conventions"></span></h3></div> <ul><li>Standard article <a href="/wiki/Wikipedia:Naming_conventions" class="mw-redirect" title="Wikipedia:Naming conventions">naming conventions</a> apply; in particular, use <a href="/wiki/Sentence_case" class="mw-redirect" title="Sentence case">sentence case</a>, do not use <a href="/wiki/Title_case" title="Title case">title case</a>. Specifically, do not <a href="/wiki/Capitalization" title="Capitalization">capitalize</a> regular nouns except when they come at the beginning of the category name.</li> <li>When naming, use words and phrases which exist in <a href="/wiki/Wikipedia:V" class="mw-redirect" title="Wikipedia:V">verifiable</a> <a href="/wiki/Wikipedia:RS" class="mw-redirect" title="Wikipedia:RS">reliable sources</a> (particularly for <a href="/wiki/Outline_of_technology#Branches_of_technology" title="Outline of technology">technical subjects</a>), so that those sources may be used to support inclusion of information.</li> <li>Avoid <a href="/wiki/Wikipedia:Manual_of_Style/Abbreviations" title="Wikipedia:Manual of Style/Abbreviations">abbreviations</a>. Example: "<a href="/wiki/Category:Military_equipment_of_World_War_II" title="Category:Military equipment of World War II">Category:Military equipment of World War II</a>", not "Category:Military equipment of WW2". However, <a href="/wiki/Acronym" title="Acronym">acronyms</a> that have become the official, or generally used, name (such as <a href="/wiki/Category:NATO" title="Category:NATO">NATO</a>) should be used where there are no other conflicts.

So, rather than leave the text of a category page empty (containing only parent category declarations), adding a <a href="#Articles_with_eponymous_categories">main article</a> which describes the topic, can help with that. </p><p>However, only linking to a Wikipedia article explaining the title is often not sufficient as a description for a category. It can be helpful – to both readers and editors – to include a clear description of the category, indicating what pages it should contain, how they should be subcategorized, and so on, and linking to one or more pages as background information. </p><p>In such cases, the desired contents of the category should be described on the category page, similar to how the <a href="/wiki/Wikipedia:LSC" class="mw-redirect" title="Wikipedia:LSC">list selection criteria</a> are described in a stand-alone list. The category description should make direct statements about the criteria by which pages should be selected for inclusion in (or exclusion from) the category. This description, not the category's name, defines the proper content of the category. Do not leave future editors to guess about what or who should be included from the title of the category. Even if the selection criteria might seem obvious to you, an explicit standard is helpful to others, especially if they are less familiar with the subject. </p><p>The description can also contain links to other Wikipedia pages, in particular to other related categories which do not appear directly as subcategories or parent categories, and to relevant categories at <a href="/wiki/Wikipedia:Wikimedia_sister_projects" title="Wikipedia:Wikimedia sister projects">sister projects</a>, such as <a href="/wiki/Wikipedia:Commons" class="mw-redirect" title="Wikipedia:Commons">Commons</a>. Another technique that can be used is described at <a href="/wiki/Wikipedia:Classification" class="mw-redirect" title="Wikipedia:Classification">Wikipedia:Classification</a>. Like <a href="/wiki/Wikipedia:Disambiguation" title="Wikipedia:Disambiguation">disambiguation</a> pages, category pages should not contain either citations to <a href="/wiki/Wikipedia:Identifying_reliable_sources" class="mw-redirect" title="Wikipedia:Identifying reliable sources">reliable sources</a> or <a href="/wiki/Wikipedia:External_links" title="Wikipedia:External links">external links</a>. </p><p>Various templates have been developed to make it easier to produce category descriptions; see <a href="/wiki/Category:Category_namespace_templates" title="Category:Category namespace templates">Category namespace templates</a>.

To make navigating large categories easier, a table of contents can be used on the category page.

When categorized, files are not included in the count of articles in the category, but are displayed in a separate section with a thumbnail and the name for each. A category can mix articles and images, or a separate file/image category can be created. A file category is typically a subcategory of the general category about the same subject, and a subcategory of the wider category for files, <a href="/wiki/Category:Wikipedia_files" title="Category:Wikipedia files">Category:Wikipedia files</a>.

To prevent the thumbnail preview of images from appearing in a category, __NOGALLERY__ should be added to the text of the category.

See <a href="/wiki/Template:Infobox_roller_coaster" title="Template:Infobox roller coaster">Template:Infobox roller coaster</a> for an example that only adds a category by manufacturer if it exists, and otherwise uses a hidden category. </p><p>However, it is recommended that articles not be placed in ordinary <i>content</i> categories using templates in this way.

However, leading articles in foreign-language-derived names which are no longer translated in English are not subject to this rule; e.g. the sort key for <a href="/wiki/El_Paso" class="mw-redirect" title="El Paso">El Paso</a> should be left as the default value (i.e. no {{DEFAULTSORT}} required).</li> <li>Spell out abbreviations and characters used in place of words so that they can be found easily in categories. For example, the sort key for <a href="/wiki/Mr._Bean" title="Mr. Bean">Mr. Bean</a> should be {{DEFAULTSORT:Mister Bean}} and <a href="/wiki/Dungeons_%26_Dragons" title="Dungeons & Dragons">Dungeons & Dragons</a> should be sorted {{DEFAULTSORT:Dungeons And Dragons}}. An exception is the times sign (×) as in "Men's 4 × 100 metre" relay; use the letter x in this case.</li> <li>Landforms (and similar) that have noun prefixes such as <a href="/wiki/Isle_of_Mull" title="Isle of Mull">Isle of Mull</a> should have the noun sorted after as {{DEFAULTSORT:Mull, Isle of}}. However, this isn't usually done for settlements and administrative divisions; for example, while <a href="/wiki/Isle_of_Wight" title="Isle of Wight">Isle of Wight</a> uses {{DEFAULTSORT:Wight, Isle of}}, the categories for the county/district are sorted "Isle of Wight". Also for settlements such as <a href="/wiki/Isle_of_Wight,_Virginia" title="Isle of Wight, Virginia">Isle of Wight, Virginia</a> the prefix isn't moved.</li> <li>Hyphens, apostrophes and periods/full stops are the only punctuation marks that should be kept in sort values. The only exception is the apostrophe in names beginning with <i>O<span class="nowrap" style="padding-left:0.1em;">'</span></i>, which should be removed. For example, <a href="/wiki/Eugene_O%27Neill" title="Eugene O'Neill">Eugene O'Neill</a> is sorted {{DEFAULTSORT:Oneill, Eugene}}. All other punctuation marks should be removed. (Commas can be added when re-ordering words, as in the previous example.)</li> <li>Entries containing numbers sometimes need special sort keys to ensure proper numerical ordering. For example, IX comes before V in alphabetical order, so <a href="/wiki/Pope_John_IX" title="Pope John IX">Pope John IX</a> might have a sort key "John 9". To get the correct sort order zero padding may be required, thus the <i>actual</i> sort key in this case is "John 09" this ensures that <a href="/wiki/Pope_John_IX" title="Pope John IX">Pope John IX</a> sorts before <a href="/wiki/Pope_John_X" title="Pope John X">Pope John X</a> – if we ever get to the hundredth Pope John, we would need to use three digits "John 009". Also note that numbers which include separators (such as commas or periods) will only have the part of the number before the first separator considered by the sorting algorithm. So <a href="/wiki/10,000_Maniacs" title="10,000 Maniacs">10,000 Maniacs</a> might have a sort key "10000 Maniacs". It is important to stick to the same system for all similar entries in a given category.</li> <li>Systematic sort keys are also used in other categories where the logical sort order is not alphabetical (for example, individual month articles in year categories such as <a href="/wiki/Category:2004" title="Category:2004">Category:2004</a> use sort keys like "*2004-04" for April). Again, such systems must be used consistently within a category.</li> <li>In some categories, sort keys are used to exclude prefixes that are common to all or many of the entries, or are considered unimportant (such as "List of" or "The"). For example, in <a href="/wiki/Category:2004" title="Category:2004">Category:2004</a> the page <a href="/wiki/2004_in_film" title="2004 in film">2004 in film</a> would have the sort key "Film", and in <a href="/wiki/Category:2004_in_Canada" title="Category:2004 in Canada">Category:2004 in Canada</a> the page <a href="/wiki/2004_Canadian_federal_budget" title="2004 Canadian federal budget">2004 Canadian federal budget</a> would have the sort key "Federal Budget".</li> <li>Use other sort keys beginning with a space (or an asterisk or a plus sign) for any "List of ..." and other pages that should appear <i>after</i> the key article and <i>before</i> the main alphabetical listings, including "Outline of" and "Index of" pages. The same technique is sometimes used to bring particular subcategories to the start of the list.</li></ul> <dl><dd>Sort order of characters <i>before</i> numbers and Latin alphabet (0–9, A–Z) is (partial list):</dd> <dd><b><code>!
