Typography
Section titles and ordinals
Section ordinals in the body text are set in Roman numerals.
Section titles are titlecased according to the output of
se titlecase
. Section titles are not all-caps or small-caps.Section titles do not have trailing periods.
Chapter titles omit the word
Chapter
, unless the word used is a stylistic choice for prose style purposes. Chapters with unique identifiers (i.e. notChapter
, but something unique to the style of the book, likeBook
orStave
) do include that unique identifier in the title, wrapped in<span epub:type="label">
.In special cases it may be desirable to retain
Chapter
for clarity. For example, Frankenstein has “Chapter” in titles to differentiate them from the “Letter” sections.
Italics
Using both italics and quotes (outside of the context of quoted dialog) is usually not necessary. Either one or the other is used, with rare exceptions.
Words and phrases that require emphasis are italicized with the
<em>
element.Strong emphasis, like shouting, may be set in small caps with the
<strong>
element.When a short phrase within a longer clause is italicized, trailing punctuation that may belong to the containing clause is not italicized.
When an entire clause is italicized, trailing punctuation is italicized, unless that trailing punctuation is a comma at the end of dialog.
Words written to be read as sounds are italicized with
<i>
.A person's internal thoughts, if they are italicized in the source, are formatted with
<q>
, styled with italics. If the thoughts are quoted, they are left as quoted.
Italicizing individual letters
Individual letters that are used in context as a phoneme are italicized with an
<i epub:type="z3998:phoneme">
element. They are sentence-cased and not followed by periods.Plural phonemes are formed with
’s
, to aid in clarity.
Graphemes are italicized with an
<i epub:type="z3998:grapheme">
element.When a word is being spelled out, the individual letters of the word are set as graphemes.
Individual letters that are not graphemes or phonemes (for example letters that might be referring to names, the shapes of the letters themselves, musical notes or keys, or concepts) are not italicized.
The ordinal
nth
is set with an italicizedn
, without a hyphen.
Italicizing non-English words and phrases
Non-English words and phrases that are not in Merriam-Webster are italicized, unless they are in a non-Roman script like Chinese or Japanese.
Non-English words that are proper names, or are in proper names, are not italicized, unless the name itself would be italicized according to the rules for italicizing or quoting names and titles. If words in the name might be mispronounced in English pronunciation, they are wrapped in a
<span xml:lang="LANGUAGE">
element to assist screen readers with pronunciation. Most proper names of people or places do not require this, but occasionally there may be some that do.If certain non-English words are used so frequently in the text that italicizing them at each instance would be distracting to the reader, then only the first instance is italicized. Subsequent instances are wrapped in a
<span xml:lang="LANGUAGE">
element.Words and phrases that are originally non-English in origin, but that can now be found in Merriam-Webster’s basic online search results, are not italicized. “Basic online search results” means that results from other dictionaries that may appear alongside basic search results, including results from the unabridged or legal dictionaries, do not fall under this rule and may still be obscure enough to be italicized.
Inline-level italics are set using the
<i>
element with anxml:lang
attribute corresponding to the correct IETF language tag.Block-level italics are set using an
xml:lang
attribute on the closest encompassing block element, with the style offont-style: italic
.In this example, note the additional namespace declaration, and that we target only
<blockquote>
elements that have the language tag. This is because there can be other elements, e.g.<span>
, that have a language tag but should not be italicized.Words that are in a non-English “alien” language (i.e. one that is made up, like in a science fiction or fantasy work) are italicized and given an IETF language tag in a custom namespace. Custom namespaces begin consist of
x-TAG
, whereTAG
is a custom descriptor of 8 characters or less.Words that are in an unknown language have their
xml:lang
attribute set tound
.Some phrases that are not English in origin but that that are common in English prose, and which begin in a word that could be confused with an English word, are always italicized to prevent confusion. An incomplete list follows:
sic
a posteriori
a priori
a fortiori
ad absurdum
ad hominem
ad infinitum
ad interim
ad nauseam
in absentia
in camera
in loco parentis
in situ
in statu quo
in toto
in vitro
inter alia
more suo
Italicizing or quoting newly-used English words
When introducing new terms, non-English or technical terms are italicized, but terms composed of common English are set in quotation marks.
English neologisms in works where a special vocabulary is a regular part of the narrative are not italicized. For example science fiction works may necessarily contain made-up English technology words, and those are not italicized.
Italics in names and titles
Place names, like pubs, bars, or buildings, are not quoted.
The names of publications, music, and art that can stand alone are italicized; additionally, the names of transport vessels are italicized. These include, but are not limited to:
Periodicals like magazines, newspapers, and journals.
Publications like books, novels, plays, and pamphlets, except “holy texts,” like the Bible or books within the Bible.
Long poems and ballads, like the Iliad, that are book-length.
Long musical compositions or audio, like operas, music albums, or radio shows.
Long visual art, like films or a TV show series.
Visual art, like paintings or sculptures.
Transport vessels, like ships.
The names of short publications, music, or art, that cannot stand alone and are typically part of a larger collection or work, are quoted. These include, but are not limited to:
Short musical compositions or audio, like pop songs, arias, or an episode in a radio series.
Short prose like novellas, short stories, or short (i.e. not epic) poems.
Chapter titles in a prose work.
Essays or individual articles in a newspaper or journal.
Short visual art, like short films or episodes in a TV series.
Examples
Taxonomy
Binomial names (generic, specific, and subspecific) are italicized with a
<i>
element having thez3998:taxonomy
semantic inflection.Genus, tribe, subfamily, family, order, class, phylum or division, and kingdom names are capitalized but not italicized.
If a taxonomic name is the same as the common name, it is not italicized.
The second part of the binomial name follows the capitalization style of the source text. Modern usage requires lowercase, but older texts may set it in uppercase.
Exceptions
Epigraphs, bridgeheads, and some other types of heading matter are set in italics by default. Text that in a Roman-set context would be italicized (like non-English words or phrases, or titles of books) are thus set in Roman in that heading matter, to contrast against the default italics. However, if due to this rule the entire block would be set in Roman instead of italics, thus lending the block an unexpected appearance, then the contrasting Roman is discarded and the default italics are preserved.
Capitalization
In general, capitalization follows modern English style. Some very old works frequently capitalize nouns that today are no longer capitalized. These archaic capitalizations are removed, unless doing so would change the meaning of the work.
Titlecasing, or the capitalization of titles, follows the formula used in the
se titlecase
tool.Text in all caps is almost never correct typography. Instead, such text is changed to the correct case and surround with a semantically-meaningful element like
<em>
(for emphasis),<strong>
(for strong emphasis, like shouting) or<b>
(for unsemantic formatting required by the text).<strong>
and<b>
are styled in small-caps by default in Standard Ebooks.When something is addressed as an apostrophe,
O
is capitalized.Names followed by a generational suffix, like
Junior
orSenior
, have the suffix uppercased if the suffix is part of the person's name.Occasionally,
junior
orsenior
may be used to refer to a younger or elder person having the same last name, but not necessarily the same first name. In these cases, the suffix is lowercased as it is not part of their name, but rather describing their generational relation.
Indentation
Paragraphs that directly follow another paragraph are indented by 1em.
The first line of body text in a section, or any text following a visible break in text flow (like a header, a scene break, a figure etc.), is not indented, with the exception of block quotations.
Body text following a block quotation is indented only if the text begins a new semantic paragraph. Otherwise, if the body text following a block quotation is semantically part of the paragraph preceding the block quotation, it is not indented. Such non-indented paragraphs have
class="continued"
, which removes the default indentation.
Headers
Titles or subtitles that are entirely non-English-language are not italicized. However, they do have an
xml:lang
attribute to assist screen readers in pronunciation. Titles or subtitles that are in English but contain non-English components have those components italicized according to the general rules for italics.
Chapter headers
Epigraphs in chapters have the quote source set in small caps, without a leading em dash and without a trailing period.
Ligatures
Ligatures are two or more letters that are combined into a single letter, usually for stylistic purposes. In general they are not used in modern English spelling, and are replaced with their expanded characters.
Words in non-English languages like French may use ligatures to differentiate words or pronunciations. In these cases, ligatures are retained.
Punctuation and spacing
Sentences are single-spaced.
Periods and commas are placed within quotation marks; i.e. American-style punctuation is used, not logical (AKA “British” or “new”) style.
If dialog ends in a semicolon, the semicolon is placed within the closing quotation mark. Otherwise, semicolons always go outside of quotation marks.
Ampersands are preceded by a no-break space (U+00A0).
Some older works include spaces in common contractions; these spaces are removed.
Quotation marks
“Curly” or typographer’s quotes, both single and double, are always used instead of straight quotes. This is known as “American-style” quotation, which is different from British-style quotation which is also commonly found in both older and modern books.
Quotation marks that are directly side-by-side are separated by a hair space ( or U+200A) character.
Words with missing letters represent the missing letters with a right single quotation mark (
’
or U+2019) character to indicate elision.Elision is not to be confused with a glottal stop, which may sometimes occur in non-English languages like Hawaiian. Glottal stops that are not elided letters are represented with a turned comma (
ʻ
or U+02BB), not the similar-looking left single quotation mark (‘
or U+2018).Rarely, in older texts some common last names are rendered using a left single quotation mark (
‘
or U+2018) instead of a superscriptc
. This is a matter of typography, and is not the actual spelling of such names. These names are changed to their equivalent modern spelling.
Ditto marks are set with the right double quotation mark glyph (
”
or U+201D), This is not to be confused with the ditto mark glyph (〃
or U+3003), which is for non-Latin scripts only, or the quotation mark glyph ("
or U+0022).Some idiomatic phrases are not set with scare quotes:
... to a T.
Ellipses
The ellipsis glyph (
…
or U+2026) is used for ellipses, instead of consecutive or spaced periods.When ellipses are used as suspension points (for example, to indicate dialog that pauses or trails off), the ellipses are not preceded by a comma.
Ellipses used to indicate missing words in a quotation require keeping surrounding punctuation, including commas, as that punctuation is in the original quotation.
A word joiner (U+2060), followed by a hair space ( or U+200A) glyph, followed by another word joiner (U+2060), are located before all ellipses that do not begin a paragraph, and that are not directly preceded by
“
.A regular space is located after all ellipses that do not end a paragraph and that are not followed by punctuation.
A hair space ( or U+200A) glyph is located between an ellipsis and any punctuation that follows directly after the ellipsis, unless that punctuation is a quotation mark, in which case there is no space at all between the ellipsis and the quotation mark.
Dashes
There are many kinds of dashes, and the run-of-the-mill hyphen is often not the correct dash to use. In particular, hyphens are not used for things like date ranges, phone numbers, or negative numbers.
Dashes of all types do not have white space around them.
Figure dashes (
‒
or U+2012) are used to indicate a dash in numbers that aren’t a range, like phone numbers.Hyphens (
-
or U+002D) are used to join words, including double-barrel names, or to separate syllables in a word. The Unicode hyphen (U+2010) is not used.Minus sign glyphs (
−
or U+2212) are used to indicate negative numbers, and are used in mathematical equations instead of hyphens to represent the “subtraction” operator.En dashes (
–
or U+2013) are used to indicate a numeric or date range; to indicate a relationship where two concepts are connected by the word “to,” for example a distance between locations or a range between numbers; or to indicate a connection in location between two places. En dashes are preceded and followed by the invisible word joiner glyph (U+2060).Non-break hyphens (
‑
or U+2011) are used when a single word is stretched out by a speaker for prosodic effect.
Em dashes
Em dashes (—
or U+2014) are typically used to offset parenthetical phrases.
Em dashes are preceded by the invisible word joiner glyph (U+2060).
Interruption in dialog is set by a single em dash, not two em dashes or a two-em dash.
Partially-obscured words
A partially-obscured word is a word that the author chooses to not divulge by consistently obscuring some or all of it. This is not the same as an interruption in dialog, which may interrupt a word, but not obscure it in the same stylistic sense.
Em dashes are used for partially-obscured years and totally-obscured days of the month.
A regular hyphen is used in partially-obscured years where only the last number is obscured, and in partially-obscured days of the month.
A non-breaking hyphen (
‑
or U+2011) is used when a single letter is obscured in a word.A two-em dash (
⸺
or U+2E3A) preceded by a word joiner glyph (U+2060) is used in partially obscured words.If both the start and end of a partially-obscured word are visible, a word joiner is placed on both sides of the two-em-dash.
A three-em dash (
⸻
or U+2E3B) is used for completely obscured words.
Numbers, measurements, and math
Coordinates are set with the prime (
′
or U+2032) or double prime (″
or U+2033) glyphs, not single or double quotes.Ordinals for Arabic numbers are as follows:
st
,nd
,rd
,th
.Numbers in a non-mathematical context are spelled out in the following cases:
If they are from 0–100.
If they are whole numbers from 0–100 and are made greater by being paired with words like
hundred
,thousand
,million
, and so on.If they begin a sentence.
If they are simple fractions.
If a series of numbers is close together in a sentence, and one would be spelled out but another wouldn’t, spell out all numbers within that context to maintain visual consistency.
The plural form of spelled-out numbers is formed without an apostrophe. However the possessive or contracted form does include an apostrophe.
Numbers of four or more digits should include commas at every 3rd decimal place.
Roman numerals
Roman numerals are set using uppercase ASCII, not the Unicode Roman numeral glyphs.
Roman numerals have the semantic inflection of
z3998:roman
.Roman numerals are not followed by trailing periods, except for grammatical reasons.
Roman numerals are not followed by ordinal indicators.
Fractions
Fractions are set in their appropriate Unicode glyph, if a glyph available; for example,
½
,¼
,¾
and U+00BC–U+00BE and U+2150–U+2189.If a fraction doesn’t have a corresponding Unicode glyph, it is composed using the fraction slash Unicode glyph (
⁄
or U+2044) and superscript/subscript Unicode numbers. See this Wikipedia entry for more details.There is no space between a whole number and its fraction.
Measurements
Dimension measurements are set using the Unicode multiplication glyph (
×
or U+00D7), not the ASCII letterx
orX
.Feet and inches in shorthand are set using the prime (
′
or U+2032) or double prime (″
or U+2033) glyphs (not single or double quotes), with a no-break space (U+00A0) separating consecutive feet and inch measurements.When forming a compound of a number and unit of measurement in which the measurement is abbreviated, the number and unit of measurement are separated with a no-break space (U+00A0), not a dash. For exceptions in money, see 8.8.8.
Punctuation in abbreviated measurements
See here for general abbreviation rules that also apply to measurements.
Abbreviated SI units are set in lowercase without periods. They are not initialisms.
Abbreviated English, Imperial, or US customary units that are one word are set in lowercase with a trailing period. They are not initialisms.
The one exception is
G
(i.e.G-force
), which is an initialism that is set without a period.Abbreviated English, Imperial, or US customary units that are more than one word (like
hp
forhorse power
ormph
formiles per hour
) are set in lowercase without periods. They are not initialisms.
Math
In works that are not math-oriented or that don’t have a significant amount of mathematical equations, equations are set using regular HTML and Unicode.
Operators and operands in mathematical equations are separated by a space.
Operators like subtraction (
−
or U+2212), multiplication (×
or U+00D7), and equivalence (≡
or U+2261) are set using their corresponding Unicode glyphs, not a hyphen orx
. Almost all mathematical operators have a corresponding special Unicode glyph.Simple in-line variables are set individually with the
<var>
tag.
In works that are math-oriented or that have a significant amount of math, all variables, equations, and other mathematical objects are set using MathML.
When MathML is used in a file, the
m
namespace is declared at the top of the file and used for all subsequent MathML code, as follows:This namespace is declared and used even if there is just a single MathML equation in a file.
When possible, Content MathML is provided in an additional
<m:annotation-xml>
element. (This may not always be possible depending on the complexity of the work.)Each
<m:math>
element has analttext
attribute.The
alttext
attribute describes the contents in the element in plain-text Unicode according to the rules in this specification.Operators in the
alttext
attribute are surrounded by a single space.
When using Presentation MathML,
<m:mrow>
is used to group subexpressions, but only when necessary. Many elements in MathML, like<m:math>
and<m:mtd>
, imply<m:mrow>
, and redundant elements are not desirable. See this section of the MathML spec for more details.If a Presentation MathML expression contains a function, the invisible Unicode function application glyph (U+2061) is used as an operator between the function name and its operand. This element looks exactly like the following, including the comment for readability:
<m:mo><!--hidden U+2061 function application--></m:mo>
. (Note that the preceding element contains an invisible Unicode character! It can be revealed with these unicode-names
tool.)Expressions grouped by parenthesis or brackets are wrapped in an
<m:mrow>
element, and fence characters are set using the<m:mo fence="true">
element. Separators are set using the<m:mo separator="true">
element.<m:mfenced>
, which used to imply both fences and separators, is deprecated in the MathML spec and thus is not used.If a MathML variable includes an overline, it is set by combining the variable’s normal Unicode glyph and the Unicode overline glyph,
‾
(U+203E), in a<m:mover>
element. However in thealttext
attribute, the Unicode combining overline,◌̅
(U+0305), is used to represent the overline in Unicode.
Ratios are expressed with the Unicode ratio character (
∶
or U+2236) surrounded by spaces, not a colon. The ratio character is also used for logical comparisons in non-mathematical contexts, like analogies in running prose.
Money
Typographically-correct symbols are used for currency symbols.
Currency symbols are not abbreviations.
£sd shorthand
£sd shorthand is a way of denoting pre-decimal currencies (pounds, shillings, and pence) common in England and other parts of the world until the 1970s.
There is no white space between a number and an £sd currency symbol.
Abbreviated currencies used in £sd shorthand are wrapped in
<abbr>
elements.Abbreviated currencies used in £sd shorthand are followed by periods.
Dates
Years with 4 digits are set without commas, but years with 5 digits or more include commas at every 3rd decimal place.
Latinisms
Latinisms that can be found in a modern dictionary are not italicized, with some exceptions. Examples of Latinisms that are not italicized include
e.g.
,i.e.
,ad hoc
,viz.
,ibid.
,etc.
.Exception:
inst.
, the abbreviation ofinstante mense
, is not italicized.
Whole passages of Latin language and Latinisms that aren’t found in a modern dictionary are italicized.
&c.
is not used, and is replaced withetc.
.For
Ibid.
, see Endnotes.Latinisms that are abbreviations are set in lowercase with periods between words and no spaces between them, except
BC
,AD
,BCE
, andCE
, which are set without periods, in small caps, and wrapped with<abbr epub:type="se:era">
:
Initials and abbreviations
Acronyms (terms made up of initials and pronounced as one word, like
NASA
,SCUBA
, orNATO
) are set in small caps, without periods, and are wrapped in an<abbr epub:type="z3998:acronym">
element with corresponding CSS.Initialisms (terms made up of initials in which each initial is pronounced separately, like
M.P.
,P.S.
, orU.S.S.R.
) are set with periods and without spaces (with some exceptions that follow) and are wrapped in an<abbr epub:type="z3998:initialism">
element.When an abbreviation that is not an acronym contains a terminal period, its
<abbr>
element has the additionaleoc
class (End of Clause) if the terminal period is also the last period in clause. Such sentences do not have two consecutive periods.Initials of people’s names are each separated by periods and spaces. The group of initials is wrapped in an
<abbr epub:type="z3998:*-name">
element. The correct semantic is selected fromz3998:personal-name
(a complete personal name including last name),z3998:given-name
(a person's given, or first, name(s), and/or middle name), orz3998:surname
(a person's last name). If it’s unclear whether a name is a first or last name,z3998:personal-name
is used as a catchall.Academic degrees are wrapped in an
<abbr epub:type="z3998:name-title">
element. Degrees that consist of initials are set with a period between each initial. Degrees that consist of initials followed by abbreviated words are set with a hair space before the word.Some degrees are exceptions:
LL.D.
does not have a period inLL
, because it indicates the pluralLegum
.
Postal codes and abbreviated US states are set in all caps, without periods or spaces, and are wrapped in an
<abbr epub:type="z3998:place">
element.Abbreviations that are abbreviations of a single word, and that are not acronyms or initialisms (like
Mr.
,Mrs.
, orlbs.
) are set with<abbr>
.Abbreviations ending in a lowercase letter are set without spaces between the letters, and have a trailing period.
Abbreviations without lowercase letters are set without spaces and without a trailing period.
Abbreviations that describes the next word, like
Mr.
,Mrs.
,Mt.
, andSt.
, are set with a no-break space (U+00A0) between the abbreviation and its target.
Compass points are separated by periods and spaces. The group of points are wrapped in an
<abbr epub:type="se:compass">
element.
Exceptions
The following are not abbreviations, and are set without periods or spaces.
A1
BB
, when referring to a BB gun or its projectiles.OK
SOS
SS
, when referring to collars of SS.
The following are initialisms, but are set without periods or spaces:
TV
, i.e.television
.AC
andDC
, when referring to electrical current.G
, when used in the sense ofG-force
. Also see 8.8.7.4.2.Stock ticker symbols.
The following are abbreviations, but are not initialisms. Unlike almost all other abbreviations, they are in all caps and only have a period at the end.
MS.
(manuscript)MSS.
(manuscripts)M.
(Monsieur)MM.
(Messieurs)
A.B.C.
, when used in the sense of the alphabet, is not an abbreviation, and is set with periods between the letters. But other uses, likeA.B.C. shops
, are abbreviations. (The abbreviation inA.B.C. shop
stands for “Australian Broadcasting Corporation.”)Company names and brand marks which may be abbreviations, but are stylized without periods by the brand, are kept in the style preferred by the brand.
The abbreviations
1D
,2D
,3D
, and4D
, meaning first, second, third, and fourth dimensions, are abbreviations but do not have a trailing period.The words
recto
andverso
are sometimes abbreviated with an initial and a superscripto
. They are regular abbreviations, set without periods, and theo
is superscripted with<sup>
.
Times
Times in a.m. and p.m. format are set in lowercase, with periods, and without spaces.
a.m.
andp.m.
are wrapped in an<abbr>
element.
Times as digits
Digits in times are separated by a colon, not a period or comma.
Times written in digits followed by
a.m.
orp.m.
are set with a no-break space (U+00A0) between the digit anda.m.
orp.m.
.
Times as words
Words in a spelled-out time are separated by spaces, unless they appear before a noun, where they are separated by a hyphen.
Times written in words followed by
a.m.
orp.m.
are set with a regular space between the time anda.m.
orp.m.
.Military times that are spelled out (for example, in dialog) are set with dashes. Leading zeros are spelled out as
oh
.
Chemicals and compounds
Molecular compounds are set in Roman, without spaces, and wrapped in an
<abbr epub:type="se:compound">
element.Elements in a molecular compound are capitalized according to their listing in the periodic table.
Amounts of an element in a molecular compound are set in subscript with a
<sub>
element.
Temperatures
The minus sign glyph (
−
or U+2212), not the hyphen glyph, is used to indicate negative numbers.Either the degree glyph (
°
or U+00B0) or the worddegrees
is acceptable. Works that use both are normalized to use the dominant method.
Abbreviated units of temperature
Units of temperature measurement, like Fahrenheit or Celsius, may be abbreviated to
F
orC
.Units of temperature measurement do not have trailing periods.
If an abbreviated unit of temperature measurement is preceded by a number, the unit of measurement is first preceded by a hair space ( or U+200A).
Abbreviated units of measurement are set in small caps.
Abbreviated units of measurement are wrapped in an
<abbr epub:type="se:temperature">
element.
Scansion
Scansion is the representation of the metrical stresses in lines of verse.
When scansion marks are next to, instead of above, letters,
×
(U+00d7) indicates an unstressed syllable and/
(U+002f) indicates a stressed syllable. They are separated from each other with no-break spaces (U+00A0).When scansion marks are above letters, a combining breve,
◌̆
(U+0306), is used to indicate an unstressed syllable and a combining vertical line above,◌̍
(U+030D), is used to indicate a stressed syllable. Vertical lines are always above letters, not next to them. Indicating unstressed symbols is optional.Lines of poetry listed on a single line (like in a quotation) are separated by a space, then a forward slash, then a space. Capitalization is preserved for each line.
Legal cases and terms
Legal cases are set in italics.
Either
versus
orv.
are acceptable in the name of a legal case; if usingv.
, a period follows thev.
, and it is wrapped in an<abbr>
element.
Morse code
Any Morse code that appears in a book is changed to fit Standard Ebooks’ format.
American Morse Code
Middle dot glyphs (
·
or U+00B7) are used for the short mark or dot.En dash (
–
or U+2013) are used for the longer mark or short dash.Em dashes (
—
or U+2014) are used for the long dash (the letter L).If two en dashes are placed next to each other, a hair space ( or U+200A) is placed between them to keep the glyphs from merging into a longer dash.
Only in American Morse Code, there are internal gaps used between glyphs in the letters C, O, R, or Z. No-break spaces (U+00A0) are used for these gaps.
En spaces (U+2002) are used between letters.
Em spaces (U+2003) are used between words.
Citations
Citations are wrapped in a
<cite>
element.Citations that are the source of a quote are preceded by a space and an em dash, within the
<cite>
element.Citations within a
<blockquote>
element have the<cite>
element as the last direct child of the<blockquote>
parent.
Verses and Chapters of the Bible
Citations of passages from the Bible include the name of the book, followed by the chapter number and the verse number. The chapter and the verse numbers are separated by a colon.
All chapter and verse numbers are written in Arabic numerals. Similarly, if a book being cited is a “numbered” book, the number is also written in Arabic numerals.
If an entire chapter, instead of a particular verse, is being cited, then the citation includes the name of the book followed by the chapter number.
If a continuous range of verses is being cited, an en dash (
–
or U+2013) is placed between the verse numbers indicating the beginning and the end of the range.Ranges may also span multiple chapters within the same book:
If a discontinuous group of verses in the same chapter is being cited, each distinct verse number is separated by a comma followed by a space.
If there are multiple citations of the same book, each citation is separated by a semicolon followed by a space, and the name of the book is omitted after the first citation.
Non-Latin Scripts and Transliterations
Greek script is set in italics. All other scripts are not set in italics unless specially required by the text.
Greek
Rough breathing marks are set using their precomposed character, if available; for example,
Ἁ
