In general, most persons' names should be stated in full when they first appear in your prose and surnames along given thereafter. Common sense sometimes dictates exceptions to this rule. Very famous persons, such as Cervantes and Shakespeare, may be referred to by their surnames only. When you state someone's name fully, write the name as it appears in your source or in a reference work, including any suffixes, accent marks, and initials.
Example
Henry Louis Gates, Jr.
Do not change the name Henry Louis Gates, Jr., to Henry Louis Gates, for example or drop hyphens or omit accents in a name. In subsequent uses, you may refer to a person by the surname only--Gates (unless, of course, you refer to two or more persons with the same surname).
Suffixes with Personal Names
When you cite a person's name in full in the main text of your written work, use a suffix that is an essential part of the name--like those that indicate generation such as Jr. in English or a roman numeral. Do not place a comma before numbered suffixes. Place a comma before suffixes like Jr. and Sr.
Example
Henry Louis Gates, Jr.
In your prose, add a comma after suffixes like Jr. and Sr. if words follow; the suffix is parenthetical.
Example
On 20 January 2021, Joseph Robinette Biden, Jr., became the forty-sixth president of the United States.
To indicate possession with a name ending in a suffix, reword to avoid forming a possessive.
Example (incorrect)
Martin Luther King, Jr.'s, legacy endures.
Martin Luther King, Jr.,'s legacy endures.
Example (correct)
Martin Luther King, Jr., has an enduring legacy.
Given Names and Personal Initials
Capitalize given names of persons and the initials that stand for them. A period and a space follow each initial unless the name is entirely reduced to initials.
Example
Octavia E. Butler
JFK
George R. R. Martin
V. S. Naipaul
J. R. R. Tolkien
When a given name is hyphenated, retain the hyphen when using initials alone.
Example
Jean-Paul Sartre
J.-P. Sartre
Names of Fictional Characters
Refer to fictional characters in your text in the same way that the work of fiction does. You need not always use their full names, and you may retain titles as appropriate.
Example
Dr. Jekyll
Harry Potter (or Harry)
Madame Defarge
Names of Organizations and Groups
Capitalize the names of all types of groups and organizations--companies, institutions, learned societies, and so on--according to the rules for styling titles of English-language works. Do not capitalize initial articles with names of groups and organizations.
Example
To conduct the study, the Pew Research Center enlisted a team of statisticians.
Our teacher gave a speech before the Fondo de Cultura Economica.
Bulmer spent twelve hours a day at the Bibliotheque Nationale.
The institution houses the largest archive of the Grateful Dead's live performances.
Will you attend the Conference Internationale Emile Zola et la Naturalisme a travers le Monde?
A conference sponsored by the Zentralverband der Deutschen Geographen will take place in the fall.
Retain internal capitals in the names of organizations and corporations.
Example
YouTube
Abbreviating the name of an organization is acceptable in some contexts, in particular if you repeat the name frequently in your prose. Always spell out the name in full and identify how you are going to abbreviate it at the first mention. Avoid abbreviating the name of an organization if you use the name only a few times.
Example
The University of North Texas (UNT) is a research university recognized for its scholarship in many fields. The division of research at UNT collaborates with the office of the provost on innovative research projects and grants.
Names of Literary Periods and Cultural Movements
Capitalize the name of a literary period, cultural movement, or school of thought only when it could be confused with a generic term. By convention, the words school and movement in such names are not capitalized. Also capitalize any proper nouns in such names.
Example
Frankfurt school
Harlem Renaissance
modernism
New Criticism
Romanticism
Whenever you use the title of a source in your writing, take the title from an authoritative location in the work--for example, from the title page of a book and not from the cover. Copy the title without reproducing any unusual typography, such as capitalization or lowercasing of all letters. Standardize capitalization of the title and add a colon between the title and the subtitle.
Example
Othermindedness: The Emergence of Network Culture
Capitalizing Titles in English
When you copy an English-language title or subtitle or write the title of your own research project, use title-style capitalization: capitalize the first word, the last word, and all principle words, including those that follow hyphens in compound terms. Therefore, capitalize the following parts of speech:
nouns (The Flowers of Europe)
pronouns (Save Our Children; Some Like it Hot)
verbs (America Watches Television; What is Literature?)
adjectives (The Ugly Duckling)
adverbs (Only Slightly Corrupt; Go Down, Moses)
subordinating conjunctions (e.g., after, although, as, as if, as soon as, because, before, if, that, unless, until, when, where, while, as in Life As I Find It)
Do not capitalize the following parts of speech when they fall in the middle of a title:
prepositions (e.g., against, as, between, in, of, to, according to; as in The Artist as Critic)
coordinating conjunctions (and, but, for, nor, or, so, yet; as in Romeo and Juliet)
the to infinitives (How to Play Chess)
articles (a, an, the; as in Under the Bamboo Tree)
But capitalize an article at the start of a subtitle.
Example
"Building Libraries in Exile: The English Convents and Their Book Collections in the Seventeenth Century"
Do not capitalize the word following a hyphenated prefix if the dictionary shows the prefix and the word combined without a hyphen.
Example
Theodore Dwight Weld and the America Anti-slavery Society
When an untitled poem is known by its first line or when a short untitled message can be identified by its full text, the line or full text is used in place of the title, transcribed exactly as it appears in the source.
Example
Gertrude Stein's poem "The house was just twinkling in the moon light" is a love letter to Alice B. Toklas.
The tweet "Avoiding plagiarism: it's easy with the MLA's free online guidelines," by MLA style (@mlastyle), garnered considerable attention.
Most titles should be italicized or enclosed in quotation marks. In general, italicized the titles of long-form works, which are often but not always self-contained and independent of other works (e.g., novels, movies), and titles of works that contain other works (e.g., anthologies, television and streaming series). Use quotation marks for titles of short-form works (e.g., poems, short stories, songs) and works contained in other works (e.g., an essay in an edited collection, an episode of a television or streaming series).
Italicized Titles (see the document below)
Italicized titles of works contained in a larger work
When a work that is normally italicized (such as a novel, play, or serialized graphic narrative) appears in a larger work (Ten Plays, Internet Shakespeare Editions, and Eightball in the examples below), both titles appear in italics.
Example
Euripides's play The Trojan Women appears in the collection Ten Plays, translated by Paul Roche.
Did you use the edition of Shakespeare's Hamlet found on the Internet Shakespeare Editions website?
The graphic narrative David Boring was serialized in three issues of Daniel Clowes's comic book Eightball.
Titles in Quotation Marks (see the document below)
With some exceptions, titles in the following categories are capitalized like titles but are not italicized or enclosed in quotation marks (see the document below).
When a titles appears within a title, the internal title should be clearly distinguished from the surrounding title. How you mark that distinction depends on the way the surrounding title is styled in accordance with guidelines earlier: in quotation marks, in italics, or, at the beginning of your paper, unstyled (see the document below).
In discussions where few numbers appear, spell out those numbers that can be written in a word or two.
Example
one
two-thirds
one hundred
thirty-six
two thousand
ninety-nine
three million
twenty-one
Use numerals when more than two words are needed. Numbers not spelled out are most commonly represented by arabic numerals (1, 2, 3).
Example
2 1/2
101
137
1, 275
Number-heavy contexts
In discussions where numbers appear frequently, such as reports of experimental data, use numerals for all numbers that precede units of measurement and to express ratios.
30 inches
5 kilograms
In such contexts, express related numbers in the same style. Thus, use numerals for numbers usually spelled out if they appear alongside numbers that must be expressed as numerals.

forty-five percent
one hundred percent
thirty-five dollars
two thousand dollars
ten million dollars
sixty-eight cents
Use numerals with symbols when more than three words would be required.
Example
$5.35
$970
48.5%
In discussions involving frequent use of numbers, use numerals with symbols (e.g., $, %). Do not combine spelled forms of numbers with symbols.

Example
threes
sixes
forties
Add an s to numerals to form the plural.
Example
1990s
747s
At the start of a sentence
Spell out a number that appears at the beginning of a sentence. It is often better to reward the sentence so that the number does not appear at the beginning.
Example (incorrect)
1960 was the beginning of a transformative decade in the United States.
Example (acceptable)
Nineteen sixty was the beginning of a transformative decade in the United States.
Example (preferred)
A transformative decade began in 1960 in the United States.
Spell out a number that appears at the beginning of a sentence even when it is paired with a related numeral that is not spelled out. However, it is often better to reword the sentence so that the number does not appear at the beginning.
Example (incorrect)
250 out of 638 delegates favored the rule change.
Example (acceptable)
Two hundred and fifty out of 638 delegates favored the rule change.
Example (preferred)
The rule change was favored by 250 out of 638 delegates.
