==category article inside category ==

Please include the question "Should a page be put in a category of the same name?", e.g. should "[[Cat]]" go in [[:Category:Cats]], and maybe mention the use of |* for these cases. [[User:Kappa|Kappa]] 05:24, 24 Nov 2004 (UTC)

I have looked for an answer in the existing documentation but found none. In my opinion the article with the same name as the category should '''not''' be put in the category but in the parent category. The article can be referenced form inside the category by ''catmore'' or a link in the description of the category. [[User:MathMartin|MathMartin]] 12:42, 27 Dec 2004 (UTC)
*Well the point is how to get from the article to the category and its children, and to know that there *is* a category with that name. [[User:Kappa|Kappa]] 16:57, 27 Dec 2004 (UTC)

Ok, I did not realize this. [[User:MathMartin|MathMartin]] 20:41, 27 Dec 2004 (UTC)
:If anyone is still watching, a proposal related to this very topic is being considered at [[Wikipedia talk:Categorization]]. -- [[User:SamuelWantman|Samuel Wantman]] 02:27, 6 January 2006 (UTC)

The current norm is that a page should ''always'' be put in the category of the same name, and piped with a space so that it appears before all others. -- [[User:SamuelWantman|Samuel Wantman]] 08:22, 6 January 2007 (UTC)

==Category size==
I think we should have a recommended size for categories (both upper and lower).  Right now we have several extremes which are much to large, such as [[:Category:Websites]], and those which are much to small, where the category is so specific there's only one entry.

I suggest that we give a recommended upper limit of ~150 and a recommended lower limit of ~10.  Exceptions to this would be "gateway" categories, which are used as sorting tools (XX by nationality etc.). [[User:Oberiko|Oberiko]] 16:42, 29 Apr 2005 (UTC)
:In finnish Wikipedia there is practise that even categories where is only 1 article are acceptable in most cases, even there is a rule that says "You should not create categories with  only 1 or 2 articles". Some says that it's ok if you can expect that there is more coming in a next few years. I'd like to know what is the original rule about this, or is there any? --[[User:195.197.175.20|195.197.175.20]] 00:29, 21 January 2007 (UTC)

:The original feature seems to have been debated at [[meta:Categorization requirements#High Priority Requirements]] (about the 22nd bulleted items).  From the behavior of the categories it seems the setting of maximum number of members within a category was rejected.  I personally like not setting maximums or minimums ( other than through guidelines based on good sense ) because it emphasizes the Wiki philosophy of freedom to edit.  [[User:Pknkly|Pknkly]] ([[User talk:Pknkly|talk]]) 15:52, 25 October 2009 (UTC)

== Missing QA ==
I wanted to find info on whether the article can be categorized with a subcategory and a parent category (i.e. [[:Category:Peace treaties]] and [[:Category:Polish peace treaties]]). I thought it was against our guidelines/MoS, but I can't find any text on any category-related page to prove my point. Any help would be appreciated.--[[User:Piotrus|Piotr Konieczny aka Prokonsul Piotrus]] [[User_talk:Piotrus|<sup style="color:green;">Talk</sup>]] 04:21, 16 December 2005 (UTC)

:That should be avoided. Articles should only be put in the most specific category applicable. Only very occasionally is it appropriate to also place the article in a (grand,grand,grand-)parent category. I have read this somewhere... *googles* Found it: ''An article should not be in both a category and its subcategory, for example Microsoft Office is in Category:Microsoft software, so should not also be in Category:Software. An article with the same name as a category should usually belong only to that category, for instance, Deism belongs only in Category:Deism.'' From [[Help:Category#When_to_use_categories]]. It's a guideline. [[User:Pfctdayelise|pfctdayelise]] 04:45, 16 December 2005 (UTC)

In this case there probably should not be duplication. However, The issue is more complicated than this.   There are cases where it makes sense to put an article in a category and its parent.  For example, [[Robert Duvall]] is in [[:Category:Film actors]] as well as its subcategory [[:Category:Best Actor Oscar]].  A proposal related to this very topic is being considered at [[Wikipedia talk:Categorization]]. -- [[User:SamuelWantman|Samuel Wantman]] 02:33, 6 January 2006 (UTC)

:Hi! I concentrate on categories. I have met so many cases, when I was not sure: ...when I would like remove an article from a category, when the article is put to the subcategory as well. I mean the case of "[[:Category:Peace treaties]] and [[:Category:Polish peace treaties]]" as mentioned higher. I would apprepriate some more detailed guide on this, or to state some WP recommandition! --[[User:Oashi|Franta Oashi]] ([[User talk:Oashi|talk]]) 20:31, 10 July 2009 (UTC)
:: Or in other words, see this case: Assume I mean the page [[Trpisty]], which is in the [[:Category:Buildings and structures in the Czech Republic]]. Now let's assume that the article is also in these two categories [[:Category:Buildings and structures by country]] and [[:Category:Czech Republic]] as well. Now my questions:
:::1) Are the two latter categories explicitly surplus, thus to be removed? (Either)
:::2) As [[User:SamuelWantman|Samuel Wantman]] said (see higher), some exceptions can happen, but then shall these be explicitly marked as {{tl|Distinguished subcategory}}? (, or.)
::As I understand it now, these two "rules" are mutually exclusive, and there could not appear any other case. Please, confirm. Thanks! --[[User:Oashi|Franta Oashi]] ([[User talk:Oashi|talk]]) 20:31, 10 July 2009 (UTC)

== red link ==

"Category:Main page" has one...  Uh, there is no "Category:Main page" .  Should we remove this reference in the text?

== Consistent Spelling ==

I have made an effort to change all instances of the word "categorisation" or the like to "categorization".  I figure that since the name of the article spells it the American way, then it should be consistent throughout the entire article.  I don't mind British English, but I prefer the spellings to be the same throughout the article, and I think that if it is inconsistent, it could possibly be distracting to readers.  --[[User:Sbrools|'''Sbrools''']] <sup>([[User_talk:Sbrools|'''<span style="color:red;">talk</span>''']] . [[Special:Contributions/Sbrools|'''<span style="color:green;">contribs</span>''']])</sup> 17:10, 27 December 2006 (UTC)

== Tags & Tagging versus Categorization ==

One of the major confusions I see is people who attempt to use Wikipedia:Categories as tags/keywords.  I propose that we need something in the FAQ to clearly set forth the distinction, with examples, and (probably) a link to a somewhat longer "help" page of some sort. --[[User:Lquilter|lquilter]] 18:15, 3 February 2007 (UTC)

== New ==

This FAQ doesn't seem to explain how you create a new category. How do you do so? Thanks.

== Indexing of "Mac"s and "Mc"s ==

There has been a discussion on the [[WP:AN#Macs and Mcs|Administrators' Noticeboard]] about the practice of indexing people with a surname beginning with "Mc". If they are indexed under "Mc" then, when alphabetically sorted, they appear in a different place to the people whose surname begins with "Mac". Real life lists invariably treat the two as the same and effectively read "Mc" as "Mac". I think something could be put in the Categorization FAQ to the effect that a surname beginning with "Mc" should be indexed under "Mac". [[User:Sam Blacketer|Sam Blacketer]] 23:01, 21 February 2007 (UTC)

== Creating a category ==

The question "how do I delete a category" is there, but no instructions on how to create one. 2 things:

1. How do you make a category?<br>
2. This info should be added to the FAQ in the same manner as deleting a category, ie "how do I add a category?" -[[User:Mike Payne|Mike Payne]] 18:02, 10 April 2007 (UTC)

: Payne's request is still standing.  I have some pages that I'd categorize if I knew how.  -kdammers

::The answer is located at [[Wikipedia:Categorization#How to create categories]]. --[[User:After Midnight|After Midnight]] <sup><small>[[User talk:After Midnight|0001]]</small></sup> 20:30, 7 June 2007 (UTC)

this reference is extremely abstract and complex and of absolutely no use in beginning to create a category page[[User:Wran|Wran]] ([[User talk:Wran|talk]]) 03:25, 27 December 2009 (UTC)

==The category template does not appear==

I'm trying to fix [[Aladdin (video game)]], but the category template does not generate. How can this be fixed? [[User:67.188.172.165|67.188.172.165]] 23:10, 1 May 2007 (UTC)

:I assume this is now ok? --[[User:BozMo|BozMo]] [[user talk:BozMo|talk]] 08:05, 27 July 2007 (UTC)

==Categories on redirects==
Hello.  Should categories be added to redirect pages, or should that be avoided? [[User:Oberiko|Oberiko]] 15:31, 6 July 2007 (UTC)

== New entries in a category ==

Is it possible to "watch" a category, i.e., be notified when new articles have been added to a specific category.  --[[User:KYN|KYN]] 19:21, 31 July 2007 (UTC)
*You can monitor the category's "Related changes".... --[[User:After Midnight|After Midnight]] <sup><small>[[User talk:After Midnight|0001]]</small></sup> 03:11, 1 August 2007 (UTC)

Yes, this is what I do, but for a large category "Recent changes" may present a full page of edits in the "old" articles and it is rather tedious to see which articles have been added recently to the category.  --[[User:KYN|KYN]] 07:21, 1 August 2007 (UTC)

**It's two years later and I have the same question, I'm wondering if there have been any system improvements to do such notifications?  Clicking 'watch' on a Category adds it to my watchlist, but adding an article to the category doesn't cause anything to show up on my watchlist.  It seems reasonable that this should work.   --[[User:CliffC|CliffC]] ([[User talk:CliffC|talk]]) 19:18, 17 August 2009 (UTC)

== Joe Taddeo deletion exhibits categorical problem ==
Not sure this discussion belongs here but I didn't know where else to put it: One remarkable thing that is happening on Wikipedia is information that is notable that was collected nowhere else is being collected here. One example of that is [[:Category:Recipients of US Distinguished Flying Cross]]. Unfortunately, the US government did not keep a cumulative record of DFC recipients, therefore no one knows how many have been awarded or to whom. [http://www.dfcsociety.org/home_high.htm] Due to its collaborative nature wikipedia is producing the first ever such list, which is a remarkable, important, and appropriate thing for an encyclopedia to do.  As you know, items are not added directly to a category page but instead an article on the item must refer to the category and that produces the entry on the category page. This is a good design except sometimes the articles created for this purpose are inadequately sourced, or seem to fall short of wikipedia's notability guidelines.  One solution would be to allow direct editing of category pages and then new entries would only have pages created if there was proper information to flesh out an article. Another solution would be to assume that if the article properly belongs on the category page then it must (categorically) pass the notability and sourcing tests. The administrators should figure that out. Suffice to say, until they do they were out of line deleting the article [[Joe Taddeo]]. The only way to put him on the [[:Category:Recipients of US Distinguished Flying Cross]] page is to leave [[Joe Taddeo]] alone. The fact he won the medal is well sourced (I provided a copy of the citation) and the fact he won it is significant to anyone interested in the medal.

== Disabling Category listing ==

Is there any [[WP:MAGIC|magic word]] or some other way that would disable category listing for a page? It would be useful in sandboxes or testcase pages, specifically where categories are transcluded by templates (but wouldn't be needed). Thanks. --[[User:Qyd|Qyd]] ([[User talk:Qyd|talk]]) 14:12, 17 November 2007 (UTC)

== Include Categories within an article==
is it possible to add a template of a certain category to list all articles related to that category within an article, so that whenever a new article is added to that category, the list of articles is automatically updated in my article?  <small>—Preceding [[Wikipedia:Signatures|unsigned]] comment added by [[Special:Contributions/82.148.97.69|82.148.97.69]] ([[User talk:82.148.97.69|talk]]) 09:42, 19 November 2007 (UTC)</small><!-- Template:UnsignedIP --> <!--Autosigned by SineBot-->

::I think the category tree extension more or less does this. It's described somewhere near the bottom of [[WP:CAT]]. (But changes to the category still won't show up on the watchlist.)--[[User:Kotniski|Kotniski]] ([[User talk:Kotniski|talk]]) 20:07, 25 October 2009 (UTC)

== Redirecting '''To''' A Category Page ==

I was just wondering, is there a way to have a non-category page redirect to a category page (using ''<nowiki>#REDIRECT [[Category:blahhh]]</nowiki>''), and then '''not''' be listed in the actual category itself. (Or else it will just go in a big circle). It would be a big help if someone could help me out here. Thanks. :D

:Yes, just precede the word Category with a colon, like when you want to link directly to a category page.--[[User:Kotniski|Kotniski]] ([[User talk:Kotniski|talk]]) 20:16, 25 October 2009 (UTC)

== Are "List of ..." articles still needed? ==

"Lists are still useful for showing "missing" articles." I'm pretty sure [[Wikipedia:Requested articles]] has this problem covered in a much more organized way. So is there still validity to this point? [[User:Devourer09|<span style="color:#CC2200">Devourer09</span>]]&nbsp;([[User talk:Devourer09|<span style="color:#CC2200">t</span>]]·[[Special:Contributions/Devourer09|<span style="color:#CC2200">c</span>]]) 00:50, 16 October 2010 (UTC)

== What is a "Start-Class" ==

I came across a whole bunch of category pages called "Start-Class" Categories. There is no explanation as to what they are, and the discussion pages are all spam. Seems the FAQ should include a definition, and the category pages should include text describing what they are for. -- [[User:Francispotter|fpotter]] ([[User talk:Francispotter|talk]]) 15:57, 12 December 2010 (UTC)

== Category "History"/Snapshot of past contents ==

Due to the nature of the search terms involved with the topic, I found this almost impossible to see if this has been discussed before, perhaps at the village pump? (Search using terms like category, history, snapshots and you'll see what I mean.)

Histories are a great tool on wikipedia allowing us to read an old state of an article, find all sorts of fascinating tidbits, and allow us to be content in the knowledge that outside of the sometimes necessary surgical removal of unacceptable content (oversight/suppression) in extreme cases, all of the information is preserved at least in some form. (It comes in handy sometimes, like for relocating content deemed inappropriate to dedicated wikis.)

But for category pages, the history is just about useless.  Since categories are formed automatically from the articles & pages, there doesn't appear to be a way to view its past contents. For example: Say [[:Category:Guys named Ruprecht with white hair]] had 123,456 articles last week.  But when I check today I find it has been massively purged down to 123 articles. How can I find out what was there before, either removed or added? As near as I can tell, there's no way, or if there is, it's extremely obscure and hard to find.

Is there any way to do this? Could there ever be? There are a few category pages I like to visit now and again and without memorizing the whole thing or saving a copy each time I visit, there's no way I can accurately tell what has or hasn't changed since my last visit. Am I the only way to be frustrated by this limitation?  <span style="font-size: smaller;" class="autosigned">—Preceding [[Wikipedia:Signatures|unsigned]] comment added by [[Special:Contributions/4.254.85.27|4.254.85.27]] ([[User talk:4.254.85.27|talk]]) 04:18, 26 January 2011 (UTC)</span><!-- Template:UnsignedIP --> <!--Autosigned by SineBot-->

== What is the purpose of categories? ==

I read the FAQ under the above title, and I still don't know what the purpose is. I have never used any Category and could not possibly see why I should.

== Noticeboard ==
*[[Wikipedia:Categorization/Noticeboard]]
Currently, category-related discussions tend to be spread out over the talkpages of [[WP:CFD]]; [[WP:CAT]], [[WP:NCCAT]]; [[WP:CLS]]; and elsewhere. Awhile back, it seemed to me that having a category-related noticeboard might be nice, so I cobbled one together. Recently, some helpful person added a notice on [[WP:CAT]] about it. So at this point, I welcome others' thoughts on this. What do you think about it, and if positive, how and where do you think we should notify others of its existence? - <b>[[User:Jc37|jc37]]</b> 07:00, 14 May 2012 (UTC)

== London example ==

Currently the article says ''" browsing downwards from a list parent category, e.g. [[:Category:Cities]], should only arrive at articles that are about cities, e.g. [[London]], and not related articles e.g. [[History of London]]."'', but [[History of London]] is in the Cities category. Is the example wrong, or which article/category is wrongly categorised ? [[User:DexDor|DexDor]] ([[User talk:DexDor|talk]]) 17:38, 15 June 2012 (UTC)

== Gender bias and other biases in categorizations ==

This is related to the issues raised in the New York Times op-ed [http://www.nytimes.com/2013/04/28/opinion/sunday/wikipedias-sexism-toward-female-novelists.html "Wikipedia’s Sexism Toward Female Novelists"], on perceived bias when female American novelists are moved to their own category "American women novelists", while male novelists remain in the main category, "American novelists". As I pointed out in the talk page for the "American novelists" category, this is a significant problem not just for the category "American Novelists", but any other categorization in Wikipedia that segregates out women or those in a minority demographic group from the main category, but keeps the non-minority men in it. There should be some guidance put in effect to correct all such cases. [[User:Suw7|Suw7]] ([[User talk:Suw7|talk]]) 04:32, 25 April 2013 (UTC)

:I absolutely, 100% agree. This practice enshrines Male as the unmarked category, which encourages prejudice. It depicts Maleness as the normal or expected gender (of people, or of novelists worth mentioning) and Femaleness as a departure from a normal novelist. It's absolutely sexist and should be systematically fixed. It's the same if Wikipedia constantly points out if somebody is Black or Native American or Asian or Gay, but leaves white people and heterosexuals as the unmarked (hence, normal people) category. And it obscures and ignores the fact that Male is a gender, white is a racial category, and heterosexual is a sexual orientation. ~ [[Special:Contributions/2601:441:4400:1740:E4CA:E4C7:B143:67F3|2601:441:4400:1740:E4CA:E4C7:B143:67F3]] ([[User talk:2601:441:4400:1740:E4CA:E4C7:B143:67F3|talk]]) 03:17, 25 September 2020 (UTC)

== Portrait painters / artists ==

There are two categories:
* [[:Category:Portrait painters]]
* [[:Category:Portrait artists]]

I found this out when I began to work on subcategories, by nationality, of the portrait painters category - and then started a conversation at [[Category talk:Portrait painters]]. Should the 2 categories be merged... meaning only have one main category: Portrait artist or Portrait painter, with subcategories by nationality under the main category?

== First discuss, or just go ahead? ==
I assume that [[:Category:Judeo-Christian topics]] should become as a subcategory of [[:Category:Abrahamic religions]], while it's currently the other way around. On the talk page of the category there is a warning that hardly anyone reads talk pages of categories. Then what? Should I just go ahead and make the change without discussing with anyone? Or else, where can I discuss this? [[User:Marcocapelle|Marcocapelle]] ([[User talk:Marcocapelle|talk]]) 13:09, 23 May 2014 (UTC)

Meanwhile I'm entirely sure that it's wrong because the current categorization has become circular: [[:Category:Christianity]] is both above and under the categories mentioned in the paragraph before. [[User:Marcocapelle|Marcocapelle]] ([[User talk:Marcocapelle|talk]]) 13:24, 23 May 2014 (UTC)

This category does not include these sets amongst those listed, though they are available as articles on Wikipedia: [[ANSEL]], [[UTF-8]], and [[ANSI (disambiguation)]] (though I don't know which of these ANSI topics is the character set the program speaks of).

==Remark regarding: Are "List of ..." articles still needed==
Under this section, one can rad:  Lists are still useful for showing "missing" articles.

This seems strange to me. I thing list have entirely different (maybe complementary) function than categories. By definition, listing things is not the same as categorizing things. Categories may have tree-like structure while lists enumerate items at the same level. Whet concerns list articles, they are very useful on its own. Beside linking to individual elements, they provide additional information for each element, which enables quick and easy comparison! These things can not be mixed. --[[User:Ajgorhoe|Ajgorhoe]] ([[User talk:Ajgorhoe|talk]]) 20:49, 2 September 2017 (UTC)

== Section comparing categories with navigational templates ==

I had to discover navigational templates the hard way, and that is why I wrote the following. It is intended to replace "Are topic and hierarchy info-boxes still needed?", which I find cryptic. ("While some info-boxes are made redundant, others have useful grouping of the cross-references that cannot be done with categories" is at best poor English.) I would put it at the end of "What are categories?". I hope no one has a problem with it.

<blockquote>=== Categories compared with navigational templates ===
John Brown's Raid on Harpers Ferry is an [[John Brown's raid on Harpers Ferry|article]], a [[:Category:John Brown's raid on Harpers Ferry|category]], and a [[Template:John Brown's Raid on Harpers Ferry|navigation template]].

A [[Wikipedia:Template|template]], whose name is marked by <nowiki>{{</nowiki> before and <nowiki>}}</nowiki> after, is a collection of text and/or formatting commands, which technically exist as a page of their own. They are "called" (inserted) by placing the template name, within the [[braces (punctuation)|braces]], on a page on which that text is wanted.

A [[Wikipedia:Navigational template|navigational template]] is a collection of links on a single topic, formatted in a standard way, in a box with a border. These links can be arranged in different ways within the box. The box is placed at the right or at the foot of the pages linked in it.

There are many fewer navigation templates than categories; only important topics have them. There is no requirement that a page be linked in a navigation template, whereas every page must belong to at least one category, and almost always more.

When appropriate, however, a navigation template organizes links in a far more useful way than categories do. It permits many nuances that categories can not, or can only clumsily. For the reader, a navigation template, if it exists, makes finding related articles much faster.

Templates are more complicated to create than categories, and the Wikipedian wishing to create one may want to use an existing template as a model.</blockquote>

== Pages in both Subcategories and Parent Categories. ==

I've noticed this in [[:Category:Flora of Africa]], but I figure it's common since I see it in other wikis I edit. 
For example, something is in Flora of Africa, but also Trees of Africa and Flora of Gabon.
My practice has been to keep the page only in the specific subcategories that it fits, taking it out of the parents of those subcategories, and the text on Flora of Africa suggests that's right (at least for that category). But I'd like to initiate a discussion on it (even if it takes years to get a response, eh whatever at least I mentioned it). ~ [[Special:Contributions/2601:441:4400:1740:E4CA:E4C7:B143:67F3|2601:441:4400:1740:E4CA:E4C7:B143:67F3]] ([[User talk:2601:441:4400:1740:E4CA:E4C7:B143:67F3|talk]]) 03:20, 25 September 2020 (UTC)

== Sortkey syntax vs. "pipe-trick" ==

This page, in the section [[Wikipedia:FAQ/Categorization#How do I sort the article differently on the category page?]], is conflating the [[Help:Link#Automatic conversion of wikitext with the pipe trick|pipe trick]] with the action of using the pipe character "|" for category sorting:

:{{tq|If most or all categories should be sorted in the same way, use a {{tl|DEFAULTSORT}} tag, which looks like <nowiki>{{DEFAULTSORT:Smith, John}}</nowiki>. All categories will then sort under "Smith" unless the "pipe-trick" is used for them (see below).}}

:{{tq|For individual cases use the "pipe-trick": Expand the category notation to include the desired sorting key after a pipe sign (syntax is similar to [[Wikipedia:piped link]], but the effect is different). For example, an article categorized by <code><nowiki>[[Category:Proper category|Sorting key]]</nowiki></code> would appear under S within the category.}}

The term "pipe-trick" is twice used incorrectly here. [[Help:Link#Automatic conversion of wikitext with the pipe trick|Pipe trick]] is a specific wikilinking trick where the pipe character "|" is used without any characters at all to the right. This auto-generates the label without the parenthetical modifier. Example: <code><nowiki>[[pipe (computing)|]]</nowiki></code> is converted to <nowiki>[[pipe (computing)|pipe]]</nowiki> which is rendered as [[pipe (computing)|pipe]].

The behavior is different when sorting. The pipe character ''must'' be followed by ''some'' character for it to have any effect (a blank, for example sorts it to the top). When sorting, a pipe character with no characters at all to the right is equivalent to no pipe character at all. ''Except'', when using [[WP:HotCat|HotCat]] to remove a sortkey entirely, it is in fact actually ''required'' to leave the pipe character where it's at, and remove everything to the right of it. <small>(The fact that removing the pipe restores the sortkey ''and'' the pipe without any feedback or indication of failure is [[Wikipedia talk:HotCat/Archive 4#Why do I need to include a pipe character to remove an existing sort key?|an error trap within HotCat that's been ignored in the past]] and an issue I intend to pursue in the future.)</small>

Clearly I struggle with explaining things both clearly and concisely. Can someone please help out and reword the section without using the term "pipe-trick". Thank you. --[[User:DB1729|DB1729]] ([[User talk:DB1729|talk]]) 03:55, 24 December 2020 (UTC)

===Proposed change===
Five months and no response. I believe this is important because if an editor simply uses the "pipe-trick" as defined [[Help:Link#Automatic conversion of wikitext with the pipe trick|here]], but on a category, the result would be either: a) no effect, or b) removal of any existing sort key. Both of which are drastically different than the intention. At the very least, it is confusing.

The simplest fix is to replace 'the "pipe-trick"' with 'a [[WP:SORTKEY|sorting key]]'. I propose changing the existing wording highlighted above to the following:

:If most or all categories should be sorted in the same way, use a {{tl|DEFAULTSORT}} tag, which looks like <nowiki>{{DEFAULTSORT:Smith, John}}</nowiki>. All categories will then sort under "Smith" unless a [[WP:SORTKEY|sorting key]] is used for them (see below).

:For individual cases use a [[WP:SORTKEY|sorting key]]: Expand the category notation to include the desired sorting key after a pipe sign (syntax is similar to [[Wikipedia:piped link]], but the effect is different). For example, an article categorized by <code><nowiki>[[Category:Proper category|Sorting key]]</nowiki></code> would appear under S within the category.

Note: the current text at the end of the section "See more details at [[WP:SORTKEY]]." could then be removed as the link would already be provided.--[[User:DB1729|DB1729]] ([[User talk:DB1729|talk]]) 02:54, 2 June 2021 (UTC)
