Part of the Style and How-to Series

This Manual of Style has the simple purpose of making things look alike — it is a style guide. The following rules don't claim to be the last word. One way is often as good as another, but if everyone does it the same way, the Ireland Information Guide will be easier to read and easier to use, not to mention easier to write and easier to edit. In this regard the following quote from the authoritative The Chicago Manual of Style deserves notice:

Rules and regulations such as these, in the nature of the case, cannot be endowed with the fixity of rock-ribbed law. They are meant for the average case, and must be applied with a certain degree of elasticity.

Clear, informative and unbiased writing is always more important than presentation and formatting. Writers are not required to follow all or any of these rules: the joy of wiki editing is that perfection is not required. Copy-editing Ireland Information Guide users will refer to this manual when weeding, and pages will be gradually made to conform with this guide.

Please see Ireland Information Guide:How to edit a page for information on how to use all the different forms of markup — there is much more available than just bold or italic. This article concentrates on when to use them, although the examples usually also show the markup.

Please see Ireland Information Guide:Guide to Layout for some simple suggestions on laying out an article. For event articles, it may be a good idea to understand News Style as a convention for organising materials in a straightforward way; basically, from top to bottom in order of relevance.

Article names

See Ireland Information Guide:Naming conventions for choosing a name for your article. Bold article titles using '''three apostrophes''' — do not self-link to bold the title. Avoid putting links inside the bold title.

Links

Free links

The use of so-called "free links" to other topics, for example, [[George W. Bush]], is encouraged. Use the links for all words and terms that are relevant to your article.

Don't overdo it. Do not link every occurrence of a word; simply linking the first time the word appears will usually be enough. For dates like 25 March, wikify every time so that the date preference of the reader will be used.

Don't link words in article titles; find alternative ways to include and then link those words.

See also Ireland Information Guide:Make only links relevant to the context

Links that follow the Ireland Information Guide naming conventions are much more likely to lead to existing articles, and, if there is not yet an article about that subject, good links will make the creation of a correctly-named article much easier for later writers.

It is possible to link words that are not exactly the same as the linked article title, [[English language|English]] for example. Make sure however that it is still clear what the link refers to without having to follow the link. When making plurals, do [[language]]s. This is clearer to read in wiki form than [[language|languages]] -- and easier to type.

Try to link accurately. If an article you want to link doesn't yet exist, do a quick search to find out if that is really the case; the article may have a slightly different name than you expect.

Never use "click here" as the text for a link (since Ireland Information Guide articles could be printed) - it conveys no information at all. The text of the link should be the subject to which the link leads.

External links

Ireland Information Guide is not a link collection and an article with only links is actively discouraged, but it is appropriate to reference more detailed material from the World Wide Web. This is particularly the case when you have used a web site as an important source of information.

The syntax for referencing a URL is simple. Just enclose it in single brackets:

 [URL optional-text-after-space]

The URL must begin with http:// or another common protocol, such as ftp:// or news://.

In addition, putting URLs in plain text with no markup will make a link

Example: http://www.Ireland Information Guide.org produces: http://www.Ireland Information Guide.org

See also Ireland Information Guide:External links.

Link titles

You can add a title to an external link by supplying a text after the URL separated by a space and enclosing the whole thing in square brackets. For example, this is a bare URL:

http://en.Ireland Information Guide.org which appears as http://en.Ireland Information Guide.org

Now a title has been added:

[http://en.Ireland Information Guide.org an open-content encyclopedia] which appears as Information Guide.org an open-content encyclopedia (http://en.Ireland)

Some URLs are ugly and uninformative; then it is better if not the URL but a meaningful title is displayed. For example:

European Space Agency website (http://www.esa.int/export/esaCP/index.html)

is much more reader-friendly than

http://www.esa.int/export/esaCP/index.html

and if the URL is displayed, make it as simple as gives the desired page, e.g. remove index.html

The "printable version" of a page displays all URLs in full, including those given a title, so no information is lost.

URLs as footnotes

Without the optional text, an external reference appears as a footnote: For example,

[http://en.Ireland Information Guide.org/]

is displayed like this:

Information Guide.org/ (http://en.Ireland)

Position in article

In most cases, it is preferable to group external links together at the bottom of the article in bullet point format under the heading:

==External links==

• [http://
  
• [http://

As with other top-level headers, two equal signs should be used to markup the external links header (see Headings elsewhere in the article).

It is also possible to include an inline URL reference within the body of an article. For example:

One good example of a cooperative online community is the [http://en.Ireland Information Guide.org Ireland Information Guide, an open-content encyclopedia].

is displayed like this:

One good example of a cooperative online community is the Information Guide.org Ireland Information Guide, an open-content encyclopedia (http://en.Ireland).

This is discouraged in most situations.

Foreign-language sites

Under most circumstances, it is not particularly useful to list URLs to webpages in languages other than English under External links. However, if you feel it is necessary, include the URL but indicate what language the site is in parentheses after the listing. For example:

• El País (http://www.elpais.es/), newspaper from Madrid (in Spanish)

Note: At present, without brackets, URLs are presented as is:

• http://en.Ireland Information Guide.org/
  • http://en.Ireland Information Guide.org/

But this feature may disappear in a future release and in cases where you wish to display the URL because it is intrinsically valuable information, it is better to use the short form of the URL (host name) as the optional text:

• Information Guide.org/ en.Ireland Information Guide.org (http://en.Ireland)
  • [http://en.Ireland Information Guide.org/ en.Ireland Information Guide.org]

File type

If the link is not to an HTML file, but to a file which must be opened in an external program, such as a PDF or Microsoft Word document, a remark about that is useful to help the user decide whether opening or first downloading is preferred.

File size

If the link is to a large file (in the case of html: including the images) a note about that is useful. Someone with a slow connection may decide not to use it.

Headings

Use the == style markup for headings, not ''' (bold). Example:

==This is a heading==

which produces

Note that when ==This is a heading== is used, no blank line under the headline is needed. Extra blank lines should be removed, since formatting is an issue for the Ireland Information Guide style sheet, not the way you write your article.

If you mark headings this way, then a table of contents is automatically generated from the headings in an article, sections can be automatically numbered for users with that preference set and words within properly marked headings are given greater weight in searches. Headings also help readers by breaking up the text and outlining the article.

• Capitalize the first word and any proper nouns in headings, but leave the rest (including ordinary nouns) lower case.
• Avoid links within headings. Depending on settings, some users may not see them clearly. It is much better to put the appropriate link in the first sentence under the header.
• Overuse of sub-headings should be avoided, as it can make the article look cluttered. Short paragraphs and single sentences generally do not warrant their own sub-heading.
• In circumstances where there is not enough text to justify a sub-heading, it may be preferable to use bolded text or bullet points within a section instead of using sub-headings.

For more information, see Ireland Information Guide:Manual of Style (headings).

Capitalization

Job titles

Job titles such as president, king, or emperor are capitalized when used as a title (followed by a name), thus it is "President Bush", not "president Bush". When used generically, they should be in lower case: "Bush is the American president." However if one is using the correct formal name of an office, it is treated as a proper noun. Hence: "Bush was President of the United States", in contrast to "Bush was the U.S. president". Similarly "Louis XVI was the French king" but "Louis XVI was King of France", King of France being a title in that context. The same goes for historical offices: "Maximilian was Mexican emperor from X to Y". "Maximilian was Emperor of Mexico from X to Y". (Reference: Chicago Manual of Style 14th ed., par. 7.16; The Guardian Manual of Style (http://www.guardian.co.uk/styleguide/page/0,5817,184841,00.html), "Titles" keyword.) Exceptions may apply for specific offices; feel free to add them here.

Remember in the case of prime minister, both letters are capitalised or lower-cased together, except, obviously, when it starts a sentence. Again, when being used generically (i.e., when talking generally about prime ministers) the office is lower-cased. When reference is made to a specific office, upper case is generally used. So "there are many prime ministers around the world." but "The British Prime Minister Tony Blair, said today . . . " (However to complicate matters, some Manuals of Style, while saying "The British Prime Minister", recommend "British prime minister". A good rule of thumb is whether a definite article (the) or an indefinite article (a) is used. If the is used, capitalisation often follows. If a is used, the lowercase is preferred.)

British versus American casing

Remember also, American English tends to lowercase most titles except in the most formal settings, while British English uses capitals far more widely, with all words of a title being capitalised except for prepositions, articles and conjunctions. Many manuals endorse forms of English frowned upon by teachers of British English, who criticise what is sometimes called the 'Americanisation of English'. Cultural clashes over grammar, spelling and capitalisation/capitalization are a common experience on Ireland Information Guide. Remember that millions of people may have been taught to use a different form of English than yours, including different spellings, grammatical constructions or capitalisation. If possible, as with spelling, use capitalization rules appropriate to the cultural and linguistic context. In other words, do not enforce American capitalization rules on pages to do with British topics. Neither should one rigidly enforce British capitalisation rules on pages that are concerned with American topics. In addition, one should remember that sub-categories of English also exist; for example, within British English, there are Indian English and Hiberno-English.

Religions, deities, philosophies, doctrines and their adherents

Names of religions should be capitalised, thus Islam, Tibetan Buddhism, Judaism. Mormonism requires special care — see Ireland Information Guide:Naming_conventions_(Mormonism). Followers of a religious faith should also be capitalised thus Christian, Muslim, Jew. Whenever a faith is used as an adjective it should also be capitalised: Jewish calendar, Islamic architecture, etc.

As per the Chicago Manual of Style, deities in both monotheistic and polytheistic religions should be capitalized — i.e. God, Allah, Freya. This also applies to transcendent ideas in the Platonic sense — Good and Truth. Similarly, alternative and descriptive names for deities should be capitalized — the Lord, the Supreme Being, the Messiah. Pronouns referring to deities, or in the extreme case "who" or "whom", or nouns (other than names) referring to any material or abstract representation of any deity, human or otherwise, should not be capitalized, however.

However, philosophies, doctrines, and systems of economic thought should not be capitalised, unless the name is derived from a proper noun. Adherents of such systems, and any derived adjectives also follow this rule. Thus we have existentialism, communism, and modernist, but Luddite, Marxism, and Jeffersonian. Lowercase republican refers to a system of political thought, uppercase Republican refers to a specific Republican Party (each party name being a proper noun); similarly, lowercase fascist refers generically to the ideology, whereas uppercase Fascist refers specifically to the Mussolini's Italian Fascist Party. Capitalisation of Nazi and Nazism is preferred (reflecting the etymology), but the trend is perhaps towards lower-casing.

Names of species (animals, plants, etc)

There has been extensive discussion on Talk:WikiProject Tree of Life about the capitalisation of the common names of animals and plants. Ireland Information Guide:Naming conventions (capitalization) gives what seems in practice to be the current convention; however contrary views can be found inIreland Information Guide:Naming conventions (fauna), while Ireland Information Guide:Naming conventions sits on the fence. The majority view, with some good-natured grumbling still going on, is that in species names, all words, except those linked to a preceding word by a hyphen, are capitalised in all occurrences (including article titles). In practice this rule is universally applied to birds (e.g. Barn Owl, almost universally to other animals (e.g. Northern Elephant Seal, and increasingly applied to plants (e.g. Scots Pine. However, the common names of higher taxa (genera, families etc) are not capitalised; so we would write, "The Wavy-leafed Soap Plant is the commonest of the soap plants". Note that this is the exact opposite of the universally accepted rule with the systematic (Latin) names, where species names are not capitalised but the names of all higher taxa are: the Wavy-leafed Soap Plant has the systematic name Chlorogalum pomeridianum (genus Chlorogalum, species pomeridianum) and is a member of the family Agavaceae.

Contractions

In general, we prefer formal writing. Therefore, contractions -- such as don't, can't, won't, and so on -- are discouraged, except when you are quoting directly.

Punctuation

In most cases, simply follow the usual rules of English punctuation. A few points where the Ireland Information Guide may differ from usual usage follow.

Quotation marks

With quotation marks, we suggest splitting the difference between American and British usage.

Although it is not a rigid rule, it is probably best to use the "double quotes" for most quotations, as they are easier to read on the screen, and use 'single quotes' for "quotations 'within' quotations". This is the American style.

Note however the following problem with single quotes: if a word appears in an article with single quotes, such as 'abcd', the Ireland Information Guide:Searching facility will find it only if you search for the word with quotes (when trying this out with the example mentioned, remember that this article is in the Ireland Information Guide namespace). Since this is rarely desirable, this problem is an additional reason to use double quotes, for which this problem does not arise. It may even be a reason to use double quotes for quotations within quotations as well.

When punctuating quoted passages, put punctuation where it belongs, inside or outside the quotation marks, depending on the meaning, and not rigidly within the quotation marks. This is the British style (Fowler has good guidelines for this). For example, "Stop!" has the punctuation inside the quotation marks. However, when using "scare quotes", the comma goes outside.

Another example:

Arthur said the situation was "deplorable". (we're quoting only part of a sentence)

Arthur said, "The situation is deplorable." (full sentence is quoted)

Keep in mind that if you're quoting several paragraphs, there should be quotes at the beginning of each paragraph, but only at the end of the last paragraph.

For uniformity and to avoid complications use straight quotation marks and apostrophes:

' "

not curved (smart) ones or grave accents:

‘ ’ “ ” `

The grave accent (`) is also used as a diacritical mark to indicate a glottal stop; however, the straight quote should be used for this purpose as well (e.g., Hawai'i, not Hawai`i). If you are pasting text from Microsoft Word, remember to turn off the smart quotes feature, unmark this feature in AutoEdit and "AutoEdit during typing"! [1] (http://www.ucar.edu/communications/thisweek/announcements/post/ascii.html)

Spaces after periods

There are no current guidelines on whether to use one or two spaces after a period but it is not important as the difference only shows up in the edit box. The page itself will only display one space (unless you use   to force it otherwise). See Ireland Information Guide talk:Manual of Style (spaces after a period) for a discussion on this.

Commas

As stated by Turabian, Chicago Manual of Style, Strunk and White, and other authoritative sources, when a conjunction joins the last two elements in a series of three or more elements, a comma is used before the conjunction: "The wires were brown, blue, and green." The reason for the final serial comma is to prevent the last two elements from being confused as a unit. Consider its utility in this sentence: "The author would like to thank her parents, Sinead O'Connor and Pope John-Paul II."

Dashes

The use of dashes on Ireland Information Guide is often under dispute. Please read Ireland Information Guide:Manual of Style (dashes) and its talk page for details.

Scientific style

• See Ireland Information Guide:Technical terms and definitions
• For units of measure use SI units, see also Ireland Information Guide:Manual of Style (dates and numbers) Note that the Ireland Information Guide Style for very large numbers is 10,000 or scientific notation and not the SI notation 10 000 with a space.
• In articles about chemicals and chemistry, use IUPAC names for chemicals wherever possible, except in article titles, where the common name should be used if different, followed by mention of the IUPAC name.
• In periodic table groups, use the new IUPAC names: (these use Arabic numerals, not Roman numerals or letters).
• For mathematics and mathematical formulae, see Ireland Information Guide:WikiProject Mathematics

Sections

Introduction

All articles should have the title or subject in bold in the first line and sometimes also in italic if that word of phrase is normally in italic too; see Ireland Information Guide:Manual of Style (titles). The title or subject can almost always be made part of the first sentence, but some articles simply have names.

• The Pythagorean theorem is named for and attributed to the 6th century BC Greek philosopher and mathematician Pythagoras
  • The '''Pythagorean theorem''' is named for and attributed to the 6th century BC Greek philosopher and mathematician Pythagoras
• Tom and Jerry -- Pairing of names from Pierce Egan's Life in London
  • '''Tom and Jerry''' -- Pairing of names from Pierce Egan's ''Life in London''

If the subject of the article has more than one name, each new form of the name should be in bold on its first appearance.

• Sodium hydroxide (NaOH), also known as caustic soda or lye
  • '''Sodium hydroxide''' (Na[[oxygen|O]]H), also known as '''caustic soda''' or '''lye'''

It is preferable to make the context clear in the first few words. For example,

• In quantum physics, the Heisenberg Uncertainty Principle
  • In quantum physics, the '''Heisenberg Uncertainty Principle'''

Lead section

The lead section is the section before the first headline. It is shown above the table of contents (for pages with more than three headlines). The appropriate lead length depends on the length of the article, but should be no longer than three paragraphs in any case. See Ireland Information Guide:Lead section for more details.

"See also" and "Related topics" sections

When articles are short and don't have headings, informal references to related articles that have not been linked from free links in the text are best handled by See also:

''See also'': Internet troll, flaming

which produces

If the article is divided into sections and See also refers to a particular section only, this form should also be used, placed at the bottom of the section.

When an article is divided into sections and the See also refers to the entire article, not just a section, it should be a heading of level 2 so that it appears in the table of contents. It should be placed at the bottom of the article, but before External links. Again, do not add any links to the "See also" section that are already present in the text of the article. If you remove a redundant link from the see also section of an article, it's probably an explicit cross reference, so consider making the link in bold in the main text instead.

example

==See also==

• Internet troll
• flaming

Which appears as:

Another equally valid form is:

or more specifically:

Sometimes it is useful to have an explicit cross-reference in the text, for example, when a long section of text has been moved somewhere else, or there is a major article on a subtopic. In these cases, make the link bold so that its significance is easier to recognize. Example:

The legal situation with regard to circumcision varies from country to country (see Legal status of circumcision).

(See Ireland Information Guide:Section).

Simple tabulation

Any line that starts with a blank space becomes a fixed font width and can be used for simple tabulation. See English plural for many examples.

 foo     bar     baz
 alpha   beta    gamma

A line that starts with a blank space with nothing else on it forms a blank line which may be just what you want or not if you are one of those typists who put two spaces after a period. You can cause a blank line unknowingly if those blanks are "wrapped" to the beginning of the next line.

Usage and spelling

For the English Ireland Information Guide, there is no preference among the major national varieties of English (American, British, Canadian, and others). However, there is a certain etiquette generally accepted on Ireland Information Guide:

• Each article should have uniform spelling and not a haphazard mix of different spellings (it can be jarring to the reader). In particular, for individual words and word-endings. For example, don't use center (American) in one place and fibre (British) in another.
• Proper names should retain their original spellings. For example, United States Department of Defense and Australian Defence Force.
• Articles which focus on a topic specific to a particular English-speaking country should generally aim to conform to the spelling of that country (for instance the British "Labour Party"). A reference to "the American labour movement" (with a U) or to "Anglicization" (with a Z) may be jarring. However, a reference to "the American labour movement" would be okay on New Labour.
• When referring to the United States, please use "U.S." so as to avoid ambiguity with "us." When referring to the United States in a long abbreviation (USA, USN, USAF), periods should not be used.
• If the spelling appears in an article name, you should make a redirect page to accommodate the other variant, as with Aeroplane and Airplane, or if possible and reasonable, a neutral word might be chosen as with Glasses.
• If the spelling appears within the article text, also consider a consistent synonym such as focus or middle rather than center/centre
• If an article is predominantly written in one type of English, aim to conform to that type rather than provoking conflict by changing to another. (Sometimes, this can happen quite innocently, so please don't be too quick to make accusations!)
• Consult Ireland Information Guide articles such as English plural and American and British English differences.
• If all else fails, consider following the spelling style preferred by the first major contributor (i.e., not a stub) to the article who used a word with variant spellings in the article or the title.
• If a word or phrase is generally regarded as correct, then prefer it to an alternative that is often regarded as incorrect. Thus "alternative meaning" should be used rather than "alternate meaning" since dictionaries often discourage or do not even recognize the latter. For example, the American Heritage Dictionary "Usage Note" at alternative simply says: "Alternative should not be confused with alternate."

Words as words

Italicize words when they are being referenced in a sentence, rather than used normally. Similarly for letters.

• The term panning is derived from panorama, a word originally coined in 1787
  • The term ''panning'' is derived from ''panorama'', a word originally coined in 1787
• The letter E is the most common letter in English.

Pictures

Main article: Ireland Information Guide:Picture tutorial

Articles with a single picture are encouraged to have that picture at the top of the article, right-aligned, but this is not a hard and fast rule. Portraits with the head looking to the right should be left-aligned (looking into the article). Please put the image at the top of the article, before the text begins.

The current image markup language is more or less this:

[[Image:picture.jpg|thumb|Blah blah caption]]

Captions

Photos and other graphics should have captions unless they are "self-captioning" as in reproductions of album or book covers, or when the graphic is an unambiguous depiction of the subject of the article. For example, in a biography article, it's presumed that the portrait is that of the person in the article, thus a caption is not necessary (unless more than one person is in the picture).

See Ireland Information Guide:Captions for tips on writing captions.

Identity

This is perhaps one area where Ireland Information Guide users' flexibility and plurality are an asset, and where one would not wish all pages to look exactly alike. Nevertheless, here are some guidelines:

• When writing an article about specific people or specific groups always use the terminology which those individuals or organizations use, self identification.
• Use the most specific terminology available, thus if someone is of Ethiopian descent one would describe them as Ethiopian, not African.
• If this is objectionable often a more general name is more neutral or more accurate. For example: List of African-American composers is acceptable, but List of composers of African descent, in this case, is more useful.
• Almost always use terms as adjectives rather than nouns, thus, black people, not blacks, gay people, not gays, adults with disabilities etc.
• Do not assume that any one term is the most inclusive or accurate.

Sexuality

Avoid homosexuality and thus heterosexuality, use alternatives such as gay/lesbian/bisexual/straight/same-sex/different-sex. Avoid the use of queer (or any term) as being most inclusive. (c.f. APA Style Guide (http://www.apastyle.org/sexuality.html))

Miscellaneous notes

When all else fails

If you are faced with a fine point, please use other resources, such as The Chicago Manual of Style (from the University of Chicago Press) or Fowler's Modern English Usage (from the Oxford University Press). Where this page differs from the other sources, the usage on this page should be preferred, but please feel free to add to this page or to carry on a discussion on Ireland Information Guide_talk:Manual of Style.

Even simpler is simply to look at an article that you like and open it for editing to see how the writers and editors have put it together. You can then close the window without saving changes if you like, but look around while you're there. Almost every article can be improved. Maybe you could add some markup to make it fit this style better.

Don't get fancy

It's easier for you and whoever follows you if you don't try to get too fancy with your markup. Even with markup as suggested here, you shouldn't assume that any markup you put in is guaranteed to have a certain appearance when it is displayed.

It is easier to display the Ireland Information Guide, easier to edit or add to its articles, if we don't make the markup any more complex than is necessary to display the information in a useful and comprehensible way. A useful encyclopedia is the first goal, but ease of editing and maintaining that encyclopedia is right behind it.

Among other things, this means use HTML markup sparingly and only with good reason.

Formatting issues

Formatting issues such as font size, blank space and color are issues for the Ireland Information Guide site-wide style sheet and should not be dealt with in articles except in special cases. If for example you feel that headline fonts are too large or there should be spaces underneath headlines, these are issues for the style sheet, not article markup.
