RfC: some italicisation questions regarding catalogues, sets, collections and types of creative works

The following discussion is closed. Please do not modify it. Subsequent comments should be made on the appropriate discussion page. No further edits should be made to this discussion.


The first four of the questions below derive from a prior discussion at Talk:New Schubert Edition#Italics, the fifth was added after it turned up at Wikipedia:Featured article candidates' /Meine Seel erhebt den Herren, BWV 10/archive1:

  1. Catalogues indicated by a name that is not an actual book title:
    1. Hoboken catalogue or Hoboken catalogue?
    2. Deutsch catalogue or Deutsch catalogue (see, for instance, lead paragraph of Schubert Thematic Catalogue)?
  2. Articles about a set of works belonging to the same genre, by a single author or composer:
    1. Shakespeare's sonnets or Shakespeare's sonnets?
    2. Bach's first cantata cycle or Bach's first cantata cycle?
  3. Articles about a particular collected edition of a composer or author:
    1. Neue Mozart-Ausgabe or Neue Mozart-Ausgabe?
    2. Complete Works of Voltaire or Complete Works of Voltaire?
  4. Abbreviations of German expressions (see also somewhat related, i.e. for English titles of creative works, unresolved issue at Wikipedia talk:Manual of Style/Abbreviations#italicization of acronyms/initialisms for otherwise italicized titles):
    1. NSA
      or NSA?
    2. BWV or BWV?
  5. Interpretation of
    WP:NCM#Key signature, catalogue number, opus number, and other additions to a composition's article title
    :
    1. German Magnificat, BWV 10 (like Italian Concerto, BWV 971
      )?

--Francis Schonken (talk) 10:29, 6 June 2017 (UTC)

Baedeker

I'd like to introduce a sixth question for the RfC (sorry for the late addition, just came across it now and seems to fit in the group of issues we're addressing here):


  1. Baedeker
    1. Baedeker's
      or Baedeker's?
    2. Baedeker Guides
      or
      Baedeker Guides?

--Francis Schonken (talk) 08:17, 8 June 2017 (UTC)

Not closely related - neither are titles of creative works, abbreviated or otherwise; neither should have italic. Batternut (talk) 21:58, 8 June 2017 (UTC)

Annex

Appending another question:


  1. Regarding the common German word for an annex (to a catalogue etc.), and its abbreviation:
    1. Anhang or Anhang?
    2. Anh. or Anh.?

--Francis Schonken (talk) 12:50, 8 June 2017 (UTC)

Input

  • imho, no italics for cases 1–4, italics for case 5. --Francis Schonken (talk) 10:29, 6 June 2017 (UTC)
For added question #6: I'd write Baedeker's and Baedeker Guides. --Francis Schonken (talk) 08:17, 8 June 2017 (UTC)
For added question #7: no italics in either case imho. --Francis Schonken (talk) 12:50, 8 June 2017 (UTC)

Batternut (talk) 10:38, 7 June 2017 (UTC)

  • I truly am at a loss on this one. Compare:
  1. Bach-Werke-Verzeichnis (abbreviated as BWV)
  2. Deutsch catalogue
    (abbreviated as D or D.)
  3. Händel-Werke-Verzeichnis (abbreviated as HWV)
  4. Köchel catalogue (abbreviated as K. or KV)
  5. Ryom-Verzeichnis (abbreviated as RV)
It's all over the place! there's no pattern or consistency of any kind. (I failed to find an italic title with an italic abbreviation to complete the set of four, but I wouldn't be at all surprised if there were one.)
There are multiple issues here, including:
  1. Italicisation or not of the names of authoritative catalogues such as those
  2. Italicisation or not of non-English words and titles
I suggest selecting model examples and seeking individual consensus on each of them. FWIW, and IMAO:
  1. Johann Sebastian Bachs Werke: Herausgegeben von der Bach-Gesellschaft zu Leipzig. An identified publication, so italics
  2. Bach-Werke-Verzeichnis. Plainface. It's a catalogue
  3. BWV
    . Plainface. Standard abbreviation for that catalogue.
  4. As for Anhang and Anh. - ptooey! (and then some!) to the academic discussion about italics or not. I happen know what "ein Anhang" is, but that is utterly irrelevant. If a reader finds Anhang or Anh. in an article in English Wiki, there is nothing to tell them what it means. Narky Blert (talk) 23:59, 11 June 2017 (UTC)
  • Man, if there was ever a job for SMcCandlish, this is it. Tony1 too, while we're at it. EEng 23:56, 17 June 2017 (UTC)
  • Looks like easy stuff to me:
    1. If it's not actually a title of a work or abbreviation of one, just a conventional name, appellation, description, quote of first line, on-the-fly translation, etc., used as a surrogate name (sometimes in absence of there even being a real one), or something like a series or a library collection, it does not get stylized, either in italics or quotation marks. The guidelines already cover this in more general terms: We specify what gets italics, what gets quotation marks, and if it's not on the list, it doesn't get either. We even already mention some of these things specifically as not stylized, but we need not list every conceivable non-stylized thing, since that would be a never-ending list, and applying any stylization to content is the exception not the rule. Much of the point of MoS being a concise guideline with examples and skipping most of the obvious, rather than a massive, "cover everything anyone may ever wonder about" work like The Chicago Manual of Style or New Hart's Rules, is to extrapolate logically from what is specified, with the common reader in mind. To respond to the specific examples: neither "Hoboken catalogue" or "Deutsch catalogue" appear to be titles of works (they'd be capitalized if they were, for one thing), but are names of categorization systems; these do not take stylization.
    2. A set, series, group, or franchise of works isn't a work; thus, no stylization. The guidelines already cover this under franchises and sets/series of books.
    3. A collected edition that is published as a book is a book and thus italicized (just as a greatest hits album is an album, and a graphic novel collecting 20 issues of a comic is a book, and so is a book of an artist's paintings all of which get italics themselves as stand-alone works of visual art, etc., etc.) Don't overthink it; there is no "only one thing in the chain of works can be italicized" rule. If I write a novel, a second novel, a short story, and a poem, and they're all eventually published in a collected-works volume, that volume's and the two novels' titles get italics, the shorter works get quotation marks. There is nothing actually complicated about this.
    4. Abbreviations of italicized titles are also italicized: "J. R. R. Tolkien's LotR takes longer to read than it does to watch all the Star Trek movies, from ST:TMP onward." "A citation to Enc. Brit. isn't a very good one here, because that's a tertiary source." Etc. The guidelines cover this already, too. The fact that the BVW is "a catalogue" is irrelevant. The next volume on your shelf may be a cook book, and the one after that a romance novel. They all get italics. In the proposal below, I address the library collection as "a catalogue" (short version: not italicized, since not a book or other comparable published work). Don't get confused by words having multiple meanings. Even "book" has multiple meanings. If I divide my novel into three big chapters called "Book 1", etc., these are not italicized as books, but given quotation marks as chapters, even if they have subchapters (= more quotation marks).
    5. "Baedeker" used as a common noun (to refer to any of their publications in general), as a genericized trademark (to refer casually to travel guides even more generally), and as the company name: these take no stylization. An exact title of one of those publications is italicized, and so would be Baedeker when used as an abbreviation of a specific one or ones ("I have two London travel guides on me: Frommer's from 2015, and a much older Baedeker" – here "Baedeker" is a stand-in for the full title, Baedeker London). It looks to me like "Baekeder's" is just wrong in many cases; the possessive does not appear to be used in the titles of them since a long time ago. Modern ones appear to be titled things like Baedeker London. Also, the article List of Baedeker Guides has incorrect style, applying italics to the series name Baedeker Guides (see point above about series/sets/franchises of publications).
    6. Anhang and Anh.: Use italics, as non-English (and really should be in a {{

  • Re. #1: so,
    • Hoboken catalogue
    • Deutsch catalogue
(neither italicised). Seems logical. That's all I retain from that answer, the rest of the wordiness seemed rather confusing than helpful. --Francis Schonken (talk) 11:37, 30 July 2017 (UTC)
  • Re. #2, "... no stylization. The guidelines already cover this under franchises and sets/series of books" – unhelpful simplification: the "guidelines" indicate that the names of some franchises (sets/series) are italicised. Without examples such statement doesn't help in any direction.
  • Re. #3, "A collected edition that is published as a book ... thus italicized ... eventually published in a collected-works volume (&c)" – the question is not about collected editions published in a single book or volume, but collected editions set up as a franchise, set and/or series in multiple volumes (with different editors for separate volumes, and individual volumes often published over a period of several decades). Now according to reply #3 the names of these collected editions should be italicised without exception, while they should never be italicised according to reply #2. Doesn't help a step in any direction.

Don't see a reason why Anh. would be italicised in any of these cases. That's not how it's done in relevant literature. Not ever. --Francis Schonken (talk) 10:12, 30 July 2017 (UTC)

Proposed addition to
Wikipedia:Manual of Style/Titles#Series titles


Similarly when referring to a particular edition of a (set of) work(s), rather than to the creative work(s) contained in it:

  • Italicised when quoting the actual title of the edition, as published (
    Franz Schubert's Werke: Kritisch durchgesehene Gesammtausgabe
    )
  • Not italicised when referring to the edition by a common short title, abbreviation or custom (as in: not as printed in the edition) translation ()

--Francis Schonken (talk) 10:12, 7 June 2017 (UTC)

Proposed change for Wikipedia:Manual of Style/Abbreviations#Latin abbreviations

I'd replace the section by the following:


==Italicisation==

===Latin===

In normal usage, abbreviations of Latin words and phrases should be italicised, except AD, c., e.g., etc. and i.e., which have become ordinary parts of the English language. The expansions of Latin abbreviations should still be italicised, as with most foreign words and phrases (Anno Domini, circa, exempli gratia, et cetera, id est). These are not normally used in article prose.

Do not use &c. in the place of etc.

===Catalogues===

Catalogues may be separately published lists (e.g. Fritz Hennenberg. Das Kantatenschaffen von Gottfried Heinrich Stölzel. Leipzig, 1976) or more generally the content of a collection (e.g. the catalogue of the Music Division of the Library of Congress). In either case, an abbreviation referring to the catalogue is not italicized (e.g. HennenbergS or H. for the first example, and US-Wc for the second). This also applies when the abbreviated reference to the catalogue is an initialism derived from an actual book title, e.g. BWV not BWV when referring to the Bach-Werke-Verzeichnis


Consequently, change the lead sentence of Wikipedia:Manual of Style/Text formatting#Names and titles to: "Italics should be used for the following types of names and titles, and abbreviations thereof (apart from the exceptions mentioned at Wikipedia:Manual of Style/Abbreviations#Italicisation):" --Francis Schonken (talk) 09:37, 8 June 2017 (UTC)

  • I doubt you'll get any buy-in on this without specifying exactly what the changes are and what the rationale for each is, especially to the "Latin" section. I'm skeptical many will open the original in another window and compare it with your proposed wording side-by-side.

    I have to oppose the proposed "Catalogues" material, on the merits. The guideline already covers this: If it's an abbreviation of an italicized title, it gets italicized. This is addressed above and at the related Wikipedia talk:Manual of Style/Abbreviations#italicization of acronyms/initialisms for otherwise italicized titles discussion, by more than one respondent. You're proposing to erase one form of general consistency to impose another very narrow sort that virtually no one cares about. The one would you would undo affects orders of magnitude more articles, so it would be a net loss in consistency. It can be frustrating when lots of consistency in one direction causes minor, orthogonal inconsistency elsewhere, and someone subjectively really wants the narrow case to be consistent, but that's life. The fact is that a book and a library's collection are radically different things; one takes italics, one does not. It's pure accident that in a certain context both are called "catalogues" by some people.

    Minor quibbles: We do not borrow odd conventions of one style of bibliographic citation (a form of structured data presentation) and apply them to normal English sentences; the "." after Hennenberg's name, and again between his work's title and the location/date information, is ungrammatical in prose; a comma is called for in both cases. Also, for a lengthy construction, "e.g." should be followed by a comma. Some insist on always using one after "e.g." or "i.e.", but it can usually be dropped if what follows is only one or two words. It shouldn't be dropped before a long clause, or material containing its own clause-separating punctuation.

Mathematics variables section is wrong and needs updating

It's actually been wrong the entire time. It is supposing that plain typographic italics should be used for maths variables and that {{var}} a.k.a. <var> markup is reserved for programming variables, but this is completely incorrect and has been the entire time WP has existed.

  • "The <var> element represents a variable. This could be an actual variable in a mathematical expression or programming context, an identifier representing a constant, a symbol identifying a physical quantity, a function parameter, or just be a term used as a placeholder in prose." HTML 5.1, 2nd ed.,
    W3C
    , 3 October 2017 (the new version, written by a consortium of 100+ organizations)
  • "The var element represents a variable. This could be an actual variable in a mathematical expression or programming context, an identifier representing a constant, a symbol identifying a physical quantity, a function parameter, or just be a term used as a placeholder in prose." HTML5: A vocabulary and associated APIs for HTML and XHTML, W3C, 28 October 2014 (the currently broadly deployed version of same)
  • "The var element represents a variable. This could be an actual variable in a mathematical expression or programming context, an identifier representing a constant, a symbol identifying a physical quantity, a function parameter, or just be a term used as a placeholder in prose." HTML Living Standard, WHATWG, 6 October 2017 (the version written by a consortium consisting of Mozilla, Apple, and Opera – for once in total agreement with W3C)
  • "VAR: Indicates an instance of a variable or program argument." [ HTML 4.01 Specification, W3C 24 December 1999 (the formerly broadly deployed version); note that it does not say "an instance of a program variable or argument".

So, the only thing that's changed since HTML4 in the 1990s is explicit recognition of use for non-maths, non-code placeholders in running prose.  — SMcCandlish ¢ >ʌⱷ҅ʌ<  00:37, 7 October 2017 (UTC)

So what difference does this actually make in the rendered page? If the answer is "not much", if this is just HTML arcanery, I'll bow out and let you figure it out.
The reason that I ask is that there's this {{math}} template that I personally really dislike (see how ugly the results are at e (mathematical constant)). My main complaint is that it forces everything into serif, which I find really jarring in running sans-serif text. (I would withdraw this objection if we could just display math articles entirely in serif, which really would be better for math articles, but of course that isn't going to happen.) --Trovatore (talk) 05:46, 30 October 2017 (UTC)
Serif is less ambiguous because sans-serif fonts often don't distinguish between uppercase I (the first-person pronoun), lowercase L, the digit 1, and a vertical bar |, all of which can appear near each other in mathematics formatting. More to the point, serif is the choice of the <math> formatting, which is unavoidable for complex expressions. If we want to match its formatting for simple expressions using html markup instead of <math>, the only choice is {{math}} (with an italic variable name inside) or {{mvar}} (which combines {{math}} with the italic markup). Straight italics are wrong, because they produce a visual appearance far from the appearance of the same variables inside <math>, and {{var}} is wrong for exactly the same reason. Compare <math>x</math>: ; {{mvar|x}}: x; {{math|''x''}}: x; ''x'': x; {{var|x}}: x. The <math> and {{mvar}} options produce a curly x (although still different enough to me that I prefer using <math> everywhere to mixing the two); the italic and var options produce a straight one (at least in my rendering preferences). There's no point arguing that variables should be sans-serif to match the body text, when <math> is both unavoidable for formatting complex formulas and unchangeably serif. —David Eppstein (talk) 06:20, 30 October 2017 (UTC)
Well, but it was decided long ago that <math> should not appear in running text. I agree that serif is less ambiguous; I would actually prefer to use it for Wikipedia as a whole, but as I say that's not going to happen.
Given that, probably it's best just not to do math in running text, to the extent it can reasonably be avoided. When it can't, though, I would prefer to use sans (and in cases of ambiguity, figure something out case-by-case to avoid it). The results of {{math}} are just too jarring.
Note that it's far from unprecedented to use sans for math — the LaTeX Beamer class does it by default, and this has not prevented it from being the de-facto standard for slide preparation in academic math. --Trovatore (talk) 06:27, 30 October 2017 (UTC)
Re "it was decided" — enough things have changed since then (in particular, <math> is now merely not-very-good as opposed to the horribly mis-sized and pixelated atrocity that it used to be), so I don't think that decision is so relevant any more. And in fact, revisiting old formatting decisions is exactly what we're doing here, so saying that we decided it and shouldn't revisit that decision is not very helpful. As for beamer: sure, but it uses the same sans-serif fonts throughout, so there's no problem with body text variables looking nothing like the same variables in display formulas. —David Eppstein (talk) 06:45, 30 October 2017 (UTC)
In my view, a difference between the appearance of variables in running text versus how they appear in displayed formulas is acceptable, or at least more acceptable than the clash of typefaces within running text itself. --Trovatore (talk) 06:49, 30 October 2017 (UTC)
(
WP:CREEP that doesn't even match what people are doing. That includes conscientious maths editors, who created {{Mvar}} – they obviously want to use var markup, and it's just that MOS:ITALICS hasn't kept up with them. Someone put this "no var for math" nonsense in MOS:ITALICS, long ago, for idiosyncratic reasons. I'd bet it was "I use LaTex a lot, and it doesn't have var markup, ergo force everyone to use LaTex style so I don't have to do anything different"; not a good reason, since LaTex and HTML have different semantics, and no one actually has to follow MoS when writing, they just shouldn't interfere with people bring text into compliance with MoS later.

Haven't really looked into <math>...</math> (embedded LaTex) markup in any detail; I don't know if it supports any variable-specific markup at all, or just italics. Finding out will take some research; I don't use LaTex myself much, and doing searches on things like "variables in LaTex" brings up page after page about variables within not displayed by LaTex (i.e., variables used in LaTex commands, as macros etc, not variables in the math content being marked up).

You can certainly change fonts within LaTeX markup. For instance, to achieve sans-serif, you can use \mathsf: <math>\mathsf{x}</math> produces . The thing you have to realize, though, is that in mathematical notation changing the font of something also usually changes its meaning. One can have mathematical formulas with variables that are each the same letter but in a different font, and what that means is that they are actually different variables from each other, and the font usually tells you something about what type of object the variable stands for. So mixing serif and sans-serif for a single variable is a really bad idea, because to a trained mathematician it looks like you are talking about two variables but you only defined one of them and now you're using a different one and what does that even mean? —David Eppstein (talk) 07:22, 30 October 2017 (UTC)
Well, now, I think you're going a little overboard on the font/semantics connection here. Sure, there are Fraktur letters that mean different things from their roman or italic equivalents. But I do not ever recall serif-vs-sans being used distinctively in any serious mathematical work. --Trovatore (talk) 08:07, 30 October 2017 (UTC)
I've frequently seen sans used for computational complexity classes e.g. . I wouldn't be surprised if some of the works doing that also use as a variable for a set, path, or similar large object. —David Eppstein (talk) 15:52, 30 October 2017 (UTC)
Well, I'll concede the possibility that it might happen somewhere, sometime. It is certainly not common. I don't think very many readers would have much trouble matching up e in running text with in a displayed formula, and it just looks so much better in running sans text. --Trovatore (talk) 17:51, 30 October 2017 (UTC)
Regardless, it's good that var markup is font-agnostic, including inside {{Math}}. When it comes to LaTex, what I'd been getting at, however, was that I don't know if it has any dedicated markup for variables as a class; I knew already that it had non-semantically defined ways to change font display (e.g. imposing/removing italics, or serif, or both).  — SMcCandlish ¢ >ʌⱷ҅ʌ<  07:46, 30 October 2017 (UTC)
I am pleased to see a discussion taking place on how to format mathematical expressions. My main comments are
* All variables should be in italic.
* All mathematical constants (including e, i and pi) should be roman (upright).
* Standard operators (eg sin, cos, ln, and the differential operator d) should be roman (upright).
If we can agree on these simple rules, from the
International System of Quantities, we will have achieved something IMO. Dondervogel 2 (talk
) 13:49, 30 October 2017 (UTC)
No way you're going to get agreement on upright constants. If the ISO recommends that, it only detracts from their credibility by making clear that they haven't taken seriously the concerns of actual mathematicians. —David Eppstein (talk) 15:54, 30 October 2017 (UTC)
On this one I agree with David. ISO messed up big time on this one. Not that there was ever any need for an ISO recommendation on math styling; they should have just stayed out of it period. --Trovatore (talk) 17:54, 30 October 2017 (UTC)
Two questions
  1. I always assumed that the purpose of using an upright e for the mathematical constant was to distinguish it from a variable e. How do mathematician's make this distinction?
  2. Leaving mathematical constants aside, can we agree on the other two points (all variables in italics and standard operators upright)?
Dondervogel 2 (talk) 18:02, 30 October 2017 (UTC)
There is no important distinction to be made between variables and constants.* They are both letters that stand for values. In the form you mean it, a constant is a value that has become commonplace in the mathematical literature while a variable is a value that's defined on a one-time basis in an individual document, but that's it. In particular, mathematics variables are not the same as programming variables: they generally have a single value (just like a constant) rather than taking different values at different times. Distinctions between types of values (scalar/vector/matrix or element/set/family of sets) are generally much more important, so that's what variations in formatting should be used for. The answer to "how do you tell Euler's constant e from some other usage of e" is: don't use both meanings in a single document, and if it's not otherwise clear say what you mean.
* There is an important distinction between variables of known value, variables of unknown value (to be solved for), and variables of indeterminate value (arbitrary elements of a given set), but it's not the same distinction as the one between Euler's constant and locally-defined values that we're talking about here. Also, it's fluid, so you can't strictly assign each letter to one class or another. For instance if you're solving two equations in two unknowns by Gaussian elimination, you start with two unknown-value variables, but sometime in the middle one of the values becomes known and should be treated as such in computing the value of the other variable.
As for Stanton's question about whether LaTeX notation includes semantic markup: not really. An example from a much longer rant I wrote a while back: "xRy" could be (1) multiplication of three real numbers, (2) multiplication of a row vector, matrix, and column vector, (3) a string of terminals (lower case) and nonterminals (upper case) in a derivation from a context free grammar, (4) applying the prefix operator R to the argument y, and then another prefix operator x to the result, (5) a binary relation R on two elements x and y, (6) something else I haven't thought of. It's important that mathematical notation be easy to type and flexible enough to cover new circumstances beyond the imagination of the creator of the formatting system, and the designers of LaTeX didn't consider the cumbersomness of semantic markup worthwhile. In practice, mathematical documents will often define LaTeX macros for semantic constructs that need repeated formatting in a certain way, but that's not possible here, because there's no way to have macro definitions in our articles and have them be understood by our math formula rendering pipeline. —David Eppstein (talk) 18:17, 30 October 2017 (UTC)

To Dondervogel's second question: No. The differential d should be in italics. That is the tradition in mathematics, and I see no warrant to futz with it on the grounds of what some silly standards body thinks would tidy things up. --Trovatore (talk) 18:45, 30 October 2017 (UTC)
I think we can agree on the operators sin, cos, exp, etc being upright, but it's because that's how one formats multi-letter operators in general, and has nothing to do with how standard they are. (This one is something LaTeX has semantic markup for: \operatorname.) —David Eppstein (talk) 19:23, 30 October 2017 (UTC)
Yes, without needing to specify the rationale, I agree, those are traditionally roman. However I don't see any need for guidance on those, because in practice no one puts them in italics, except maybe just out of laziness inside <math>, and in that case they are unlikely to object when someone cleans it up. --Trovatore (talk) 19:31, 30 October 2017 (UTC)

I am not willing to read completely this entire discussion, but I want emphasize some points that seem to not appear in this discussion.

  • The opening post asserts implicitly that the only right way for writing mathematics is the way that fulfill some meta-logic (of HTML or other). I do not agree with this view: correct meta-rules have to be preferred only when they allow the rendering that is desired by the writer.
  • The choice between serif and sanserif for math variables and constants is not only done for aesthetic reasons, and the rules of readability for mathematics are not identical with the rules of readability for pure prose: when the same variable is rendered differently in different places of the same paragraph, it requires some effort for the reader to understand that the two renderings denote the same thing. This is not a difficulty for an expert, but this may be confusing for the layman (math is difficult enough by itself, no need to increase the difficulty without good reasons). Should we explain in every math article that ag (produced with {{var}}) or ag (simple italic) is the same as ag ({{math}}), ag ({{mvar}}) and (<math>)?
  • Considering that one cannot avoid <math> for some formulas, one can see from the preceding example, that the only way to have a unique shape for all variables is to use only <math>. Nevertheless, as <math> produces a bad alignment and a smaller font, it is a good compromise to use of {{mvar}} or {{math}} for inline formulas. However, for formulas containing exponents or indices, the bad alignment and the smaller font of <math> becomes an advantage (also it is easier to write in this case).

My conclusion: {{math}} and {{mvar}} should be preferred to {{var}} and simple italics for simple inline formulas (including isolated variables), and <math> should be preferred in the other cases.

IMO, the section on math variables should be updated in this way. By the way it should be noted that this section is misleading by using {{xt}}, which produces a serif font. I'll fix this. D.Lazard (talk) 09:18, 1 November 2017 (UTC) D.Lazard (talk) 09:18, 1 November 2017 (UTC)

I'm happier with the format of the maths being different from text, I don't think of English and maths or chemistry or anything like that as being the same language and prefer to be able to spot the maths in the text and pick it out easily.
By the way as well one can also use {{tmath}} for variables instead of {{mvar}} and it'll generate a proper <math>...</math> round the name and format the numbers properly as in {{tmath|x2}} gives . It can't be used easily in general instead of the math tag as it doesn't handle = nicely but it can do the simple things one wants inline. I would have hesitated to say this before because <

"The opening post asserts implicitly that the only right way for writing mathematics is the way that fulfill some meta-logic" – I implied no such thing at all. I have little care whether people prefer <math>...</math> (LaTex) markup, or plain-or-templated) wikitext (i.e. HTML) markup. If they are using HTML, then the MoS's current wording saying to use bare italics instead of the semantic <var>...</var> (wiki template: {{var}}) markup is provably incorrect, based on a misreading of (or not actually reading at all) the HTML specs.  — SMcCandlish ¢ >ʌⱷ҅ʌ<  17:32, 1 November 2017 (UTC)

Need clarification on italicizing foreign words vis-a-vis foreign song titles (
MOS:ETY

MOS:ETY says to italicize foreign words. However, what about song titles that are in a foreign language? Normally, they go in quotation marks for English song titles, but does that go for foreign song titles too? Do you italicize foreign songs and put them in quotation marks too? – Illegitimate Barrister (talkcontribs

Which is why the lang-x templates family should not force italics. Terms like "Bayerische Staatsoper" or "Bist du bei mir" don't need them. If needed (Im Westen nichts Neues, amuse-bouche, festina lente), italics can be applied in the usual manner. This was recently discussed at Template talk:Lang-de#Restoring italics and many times before elsewhere, mostly resulting in forced italics by those templates. -- Michael Bednarek (talk) 02:56, 28 October 2017 (UTC)
The fix for that is to add a |italic=no parameter. Ideally this would all be done in a meta-template; it really doesn't make much sense that every Template:Lang-xx is a completely separate thing with individually coded parameters.  — SMcCandlish ¢ >ʌⱷ҅ʌ<  04:04, 28 October 2017 (UTC)
Pending the outcome of the proposed template upgrade (see subtopic below), this will work:
Code: {{lang-es|<nowiki />''casa''<nowiki />}}
Output: [casa] Error: {{Lang-xx}}: text has italic markup (help)
A blecherous kludge, but it works. How it works: by turning off the italics started by the template, then giving the non-English term, then turning italics on again after it, which the template immediately turns back off. Uses the <nowiki /> trick to prevent the template's '' and the input's '' from being concatenated into '''' which parses as boldface plus a stray '.
A less MediaWiki-ish and more HTML/CSS-ish variant of this approach: {{lang-es|1=<span style="font-style:normal">casa</span>}}Spanish: casa.

Use of boldface for redirected terms / terms being defined

At the Heisenbug article, an editor and I have a small disagreement. There are several terms that are redirected to that article: bohrbug, mandelbug, hindenbug and schrödinbug. The MOS seems to state that, even though they're not in the lede sentence, that because they are redirects they can (or even should) be bold. There is wording in the MOS:BOLD section that seems to imply that they can be bold in both the lede section and when they are first encountered in the prose. What is the case? Should they be bold at all? Should they be bold when they are encountered in the prose. Should they be bold in both locations? Should they be bold everywhere? Walter Görlitz (talk) 15:30, 6 October 2017 (UTC)

Bold at first occurrence in the prose whether in the lead or not. Not boldfaced after that. MOS:BOLD isn't unclear about this at all: "The most common use of boldface is to highlight the first occurrence of the title word/phrase of the article (and often its synonyms) in the lead section, as well as terms that are redirected to the article or its sub-sections." There's no relationship between "that are redirected" and "in the lead section". I suppose this could be clarified by splitting this into two sentences. I'll try that in next edit.  — SMcCandlish ¢ >ʌⱷ҅ʌ<  00:07, 7 October 2017 (UTC)

Amending the discussion heading to something more meaningful - hope you don't mind.
@SMcCandlish: what is your reference for the "real" rules, as they may differ from what is actually said here? Who makes these rules, anyway?
Furthermore:
  • Neither version addresses the basic reason for which the terms had been boldfaced in this instance: they are terms being defined. This seems to be a common convention, not merely on Wikipedia. Indeed, I had always assumed this common convention was the underlying reason behind boldfacing the subject of the article in the first sentence of the text of most articles.
  • One of the points refers to following the "principle of least astonishment" for redirect targets. By boldfacing the terms we would be following this principle, just the same as we would be if all the terms we were applying it to were at the start of the section. Indeed, by insisting that the terms must not be in bold, you guys are going against this principle. Indeed I'm inclined to say that, because they aren't all in one place at the start of the section, it is more important to make them stand out.
  • Note also the message at the top of this and other MoS pages: "It is a generally accepted standard that editors should attempt to follow, though it is best treated with common sense, and occasional exceptions may apply."
  • This is only an issue because the terms are briefly mentioned in the lead as well as here. Why should such a small detail of the content of the lead dictate the formatting elsewhere in the article?
  • If these terms being defined shouldn't be boldfaced, how should they be formatted? Previously they were in italics; now they have no formatting applied to them at all. This doesn't seem right to me.

) instructions to centralize the advice on something in one place and cross-reference it from other pages where the matter comes up. At MoS pages, we also sometimes update line-items to better reflect off-WP practice that has shifted, as reflected in newer editions of mainstream style guides (doesn't come up often, since formal written English changes slowly).
The article Provenance is probably a good example. The sometimes-synonymous term provenience is bolded in the lead, since it redirects there. In the "Archaeology, anthropology, and paleontology" subsection, provenience is italicized in a words-as-words construction, but not boldfaced again. The related term find spot is boldfaced because it has not appeared in the article before, and it redirects there.  — SMcCandlish ¢ >ʌⱷ҅ʌ<  00:14, 9 October 2017 (UTC)

More of a
WP:RFD it would be deleted. There are often cases where a particular person who's not independently notable is a redir to an article (e.g. on a band, or on the company they started, or the book they wrote, or whatever) when the topic is more notable than the person. Bolding can make sense in such a case if there's a 1:1 correlation between the person and the subject (e.g. author:book, founder:company), or when all the relevant persons redirect there (guitarist, singer, bassist, drummer : band), or when the person has a section at the article (5th Duke of Fooville : List of Dukes of Fooville). But it's not good to bold someone's name in the middle of a paragraph with other people in it when the topic of the target article is not intimately connected to that particular individual and the section isn't all about him/her either.  — SMcCandlish ¢

Spacecraft names (once more)

I woulk like to raise, once again, the question of the naming of spacecraft to suggest that the passage on italicizing the names of spacecraft be clarified. A recent discussion at Talk:Gaia (Spacecraft) concerned whether the name of that spacecraft (and other unmanned spacecraft) should be italicized.

  • If we decide to reflect current Wikipedia practice, actual usage in Wikipedia has
    Cassini-Huygens
    are all italicized.
  • Alternatively, it could reflect the practice of the sponsoring organizations which tend to avoid Italics (ESA does not use italics for Hipparcos and Gaia; NASA does not use itallics for Magellan and Voyager 1).
  • We might look at other authoritative sources on this issue.
  • The Chicago Manual of Style (14th ed.) has "Names of specific ships,… spacecraft, and artificial satellites are italicized.…
    Project Apollo
    ."

Comment is welcome.--SteveMcCluskey (talk) 15:13, 11 December 2017 (UTC)

To give this discussion more focus, I suggest the following specific edit:
  • Spacecraft and satellites (including fictional): the Space Shuttle Challenger, Gaia satellite, USS Enterprise NCC-1701, Constitution-class starships (When they have different names, distinguish the name of the spacecraft from the name of the mission or series: the Eagle was the Apollo 11 lunar lander but Voyager 2).
--SteveMcCluskey (talk) 22:04, 11 December 2017 (UTC)
For clarity, the current wording is:
  • Spacecraft (often fictional): the Space Shuttle Challenger, USS Enterprise NCC-1701, Constitution-class starships (but distinguish the craft from the mission: The Eagle was the Apollo 11 lunar lander).
There is no reason for the dispute to have erupted, since the idea that a style variance would apply simply because a human isn't on board is weird nonsense. The
USS Maine (ACR-1)
sank over a century ago and has no one on board now, but isn't de-italicized. However, if adding an example of an unmanned craft will forestall pointless squabbles like this from arising in the future, them I'm all for it. However, "Spacecraft and satellites" is poor wording. Artificial satellites are spacecraft, and the Moon is a satellite. So just stick with the original "Spacecraft (often fictional)" wording; the simple act of adding an unmanned artificial satellite to the list of examples with get the point across without any further wording change in that part. The proposed clarifications to "distinguish the craft from the mission" seem reasonable, but the examples need to parse better, and we don't need all that verbiage. The combined rewrite I would support (also being clearer than just "distinguish"):
Spacecraft (including fictional): the Space Shuttle Challenger, Gaia satellite, USS Enterprise NCC-1701, Constitution-class starships. Do not italicize a mission, series, or class except where it coincides with a craft's name: the Eagle was the Apollo 11 lunar lander; Voyager 2 was the subject of the Voyager 2 mission.

Avoidance of brow-beating emphasis

I quite often come across blog/editorial/advocacy/marketing-style misuse of emphasis in constructions like "This is an intentional omission, and thus not

MOS:ITALICS
, as a counterpoint to the extant material that reads:

  • "Emphasis may be used to draw attention to an important word or phrase within a sentence, when the point or thrust of the sentence may otherwise not be apparent to readers, or to stress a contrast: Gellner accepts that knowledge must be knowledge of something."

In short, not every contrast should be stressed, but too may editors are not getting it.

Indeed, just saying that gives us draft text to use. Proposed insertion:

  • "Not every contrast should be stressed; do not brow-beat readers with material like Haplography is unintentional omission of a duplicate letter."

Abuse of emphasis in this manner is already something that can be argued against on several grounds (

MOS:TONE; and others, depending on the context), but it's an argument that is tiresome to have to re-present again and again, especially when fans of this informal and condescending writing style will wikilawyer to retain it ("There's no rule that I can't do it, and I like it better with the italics"). So, let's just have a clear MoS line-item we can cite. PS: It will also be consistent with the related item at WP:Manual of Style/Abbreviations#Expanded forms, to not do things like "NASA (National Aeronautics and Space Administration)".

More clarity may be needed re titles of works in foreign languages

This MOS page currently says:

Text in non-Latin scripts (such as Greek, Cyrillic or Chinese) should neither be italicized as non-English nor bolded, even where this is technically feasible; the difference of script suffices to distinguish it on the page. However, titles of major works that should be italicized are italicized in Latin, Greek, Cyrillic, and Hebrew scripts (but not in Chinese,[4] Japanese,[5] or Korean).[6]

This guidance provides help with Latin, Greek, Cyrillic, and Hebrew scripts and with Chinese, Japanese, and Korean writing. Conspicuous by their absence are Arabic, Devanagari, Thai, and other scripts aside from the seven that are mentioned. Is there MOS-level guidance somewhere else regarding these other scripts? For a practical application of this guidance, see {{Infobox book}}, which uses {{lang}}, which automatically italicizes certain languages and scripts. Some discussion is in progress at Template talk:Lang.

The simple fix is to change this to say "titles of major works that should be italicized are italicized in scripts that support that feature (including Latin, Greek, Cyrillic, and Hebrew); do not apply italic markup to scripts that do not (including Chinese, Japanese, and Korean)".

The word "magazine" as part of a title

At

the project have silently gone back and forth between "The Ring magazine" and "The Ring magazine
. Which of these is best practice on WP? Also, grammar-wise, I tend to go with something like this:

"... has held the Ring magazine title since..."

However, should it be this instead:

"... has held The Ring magazine title since..."?

I'm not sure why, but the latter looks clunky to me. Mac Dreamstate (talk) 21:03, 15 February 2018 (UTC)

@Mac Dreamstate: It reduces the "sea of blue" effect to use shorter link text when doing so won't be confusing, so I would lean toward "The Ring magazine". And it's normal English to drop a The from a title when it would be grammatically awkward ("Jones was a New York Times reporter for seven years before taking an editorial job the The Wall Street Journal"). It's similarly okay to lower-case a the when it's part of the grammatical structure of the surrounding sentence (i.e., would be there even if the work title didn't start with The). Not doing so can even be confusing and misleading. If three fans of The Lord of the Rings on a webboard were bashing the Shannara series as derivative, one could write of them that "According to the Lord of the Rings fans ...", where "the ... fans" means "the specific fans we just mentioned, who might be in the minority"), while "According to The Lord of the Rings fans ..." would imply a broad consensus among fans of The Lord of the Rings. Contrived example, but I've seen cases like this come up, and the one you illustrate seems to be one, because "the ... title" is the unit under discussion. It could have been "the WWE title" or something else. The "... has held The Ring magazine title" construction is confusing and seems to refer to the publication title of the magazine (i.e., it seems to imply trademark ownership), due to the ambiguity of the word "title".  — SMcCandlish ¢ 😼  08:34, 20 June 2018 (UTC)

Text formatting of references

Forgive me if this is in the wrong place. It's my understanding that references use minimal text formatting, namely that we italicize book titles and suchlike. In (what barely passes for) a discussion at Talk:P versus NP problem#MOS:BOLD it has been suggested that parts of some reference titles be bolded, even though the original authors do not use boldface. Could somebody please weigh in there before I pull all of my hair out? Cheers. nagualdesign 19:25, 23 June 2018 (UTC)

My feeling is that it is usually a mistake for authors to include mathematical formulas in their titles. But when they do, it is even more of a mistake to quote that title without properly formatting the formula as a formula. Look, both this comment and your rampage at P versus NP problem appear to be based on a misunderstanding of how mathematical notation works. The size, position with respect to the baseline, font style, and case of letters that are part of mathematical notation are all meaningful, as meaningful as which letter it is. When you change those formatting details based on aesthetics rather than based on the mathematics, you break the meaning of the formula. It is as if you were writing English but you thought that how a letter was oriented was just an aesthetic decision, so you mixed up all your d's, b's, and p's, and swapped your n's and u's for each other. It is wrong and you need to learn that it is wrong before you continue editing any more mathematical articles. —David Eppstein (talk) 19:51, 23 June 2018 (UTC)

"Five-letter rule"? I thought the rule was to lowercase words with a single unaccented syllable, and capitalize anything with multiple syllables or where the single syllable is accented.

MOS:NOBOLD explicitly forbids using boldface in expansions of acronyms. I'm sure boldface should never be partially applied to words, e.g. in expansions of portmanteaus. I'm not sure about italics though. wumbolo ^^^
