How to Cite a Thesis or Dissertation in APA

In this citation guide, you will learn how to reference and cite an undergraduate thesis, master’s thesis, or doctoral dissertation. This guide will also review the differences between a thesis or dissertation that is published and one that has remained unpublished. The guidelines below come from the 7th edition of the Publication Manual of the American Psychological Association (2020a), pages 333 and 334. Please note that the association is not affiliated with this guide.

Alternatively, you can visit EasyBib.com for helpful citation tools to cite your thesis or dissertation .

Guide Overview

Citing an unpublished thesis or dissertation, citing a published dissertation or thesis from a database, citing a thesis or dissertation published online but not from a database, citing a thesis or dissertation: reference overview, what you need.

Since unpublished theses can usually only be sourced in print form from a university library, the correct citation structure includes the university name where the publisher element usually goes.

Author’s last name, F. M. (Year published). Title in sentence case [Unpublished degree type thesis or dissertation]. Name of institution.

Ames, J. H., & Doughty, L. H. (1911). The proposed plans for the Iowa State College athletic field including the design of a reinforced concrete grandstand and wall [Unpublished bachelor’s thesis]. Iowa State University.

In-text citation example:

• Parenthetical :  (Ames & Doughty, 1911)
• Narrative :  Ames & Doughty (1911)

If a thesis or dissertation has been published and is found on a database, then follow the structure below. It’s similar to the format for an unpublished dissertation/thesis, but with a few differences:

• The institution is presented in brackets after the title
• The archive or database name is included

Author’s last name, F. M. (Year published). Title in sentence case (Publication or Document No.) [Degree type thesis or dissertation, Name of institution]. Database name.

Examples 1:

Knight, K. A. (2011). Media epidemics: Viral structures in literature and new media (Accession No. 2013420395) [Doctoral dissertation, University of California, Santa Barbara]. ProQuest Dissertations Publishing.

Trotman, J.B. (2018). New insights into the biochemistry and cell biology of RNA recapping (Document No. osu1523896565730483) [Doctoral dissertation, Ohio State University]. OhioLINK Electronic Theses & Dissertations Center.

In the example given above, the dissertation is presented with a Document Number (Document No.). Sometimes called a database number or publication number, this is the identifier that is used by the database’s indexing system. If the database you are using provides you with such a number, then include it directly after the work’s title in parentheses.

If you are interested in learning more about how to handle works that were accessed via academic research databases, see Section 9.3 of the Publication Manual.

In-text citation examples :

• Parenthetical citation : (Trotman, 2018)
• Narrative citation : Trotman (2018)

Author’s last name, F. M. (Year Published). Title in sentence case [Degree type thesis or dissertation, Name of institution]. Name of archive or collection. URL

Kim, O. (2019). Soviet tableau: cinema and history under late socialism [Doctoral dissertation, University of Pittsburgh]. Institutional Repository at the University of Pittsburgh. https://d-scholarship.pitt.edu/37669/7/Olga%20Kim%20Final%20ETD.pdf

Stiles, T. W. (2001). Doing science: Teachers’ authentic experiences at the Lone Star Dinosaur Field Institute [Master’s thesis, Texas A&M University]. OAKTrust. https://hdl.handle.net/1969.1/ETD-TAMU-2001-THESIS-S745

It is important to note that not every thesis or dissertation published online will be associated with a specific archive or collection. If the work is published on a private website, provide only the URL as the source element.

In-text citation examples:

• Parenthetical citation : (Kim, 2019)
• Narrative citation : Kim (2019)
• Parenthetical citation : (Stiles, 2001)
• Narrative citation : Stiles (2001)

We hope that the information provided here will serve as an effective guide for your research. If you’re looking for even more citation info, visit EasyBib.com for a comprehensive collection of educational materials covering multiple source types.

If you’re citing a variety of different sources, consider taking the EasyBib citation generator for a spin. It can help you cite easily and offers citation forms for several different kinds of sources.

To start things off, let’s take a look at the different types of literature that are classified under Chapter 10.6 of the Publication Manual :

• Undergraduate thesis
• Master’s thesis
• Doctoral dissertation

You will need to know which type you are citing. You’ll also need to know if it is published or unpublished .

When you decide to cite a dissertation or thesis, you’ll need to look for the following information to use in your citation:

• Author’s last name, and first and middle initials
• Year published
• Title of thesis or dissertation
• If it is unpublished
• Publication or document number (if applicable; for published work)
• Degree type (bachelor’s, master’s, doctoral)
• Thesis or dissertation
• Name of institution awarding degree
• DOI (https://doi.org/xxxxx) or URL (if applicable)

Since theses and dissertations are directly linked to educational degrees, it is necessary to list the name of the associated institution; i.e., the college, university, or school that is awarding the associated degree.

To get an idea of the proper form, take a look at the examples below. There are three outlined scenarios:

• Unpublished thesis or dissertation
• Published thesis or dissertation from a database
• Thesis or dissertation published online but not from a database

APA 7th Direct Quotes

APA Direct Quote

If a source has multiple authors, follow these guidelines.

Two  authors in a parenthetical citation:  Use an ampersand (&) between the two last names. ​ 

Two authors in the narrative:   Use  and  between the two last names. ​ 

Three or more authors:  Only cite the first author, followed by  et al.

If directly quoting, include the author, year of publication, and page number for the reference. Introduce the quote with a phrase like  according to  or state the author's last name.

• According to Smith (2017), "First-year college students struggle with the lack of sleep, good eating habits, and APA style" (p. 23).
• According to Jones and Brown (2017), "Citing in correct APA style can be challenging" (p. 25).
• Smith (2017) discovered "first-year college students struggle with lack of sleep, good eating habits, and APA style" (p. 23); what does that mean for college health officers, librarians, and teachers?

If you do not name the author in the sentence, list it with the date and page numbers after the quotation.

• She said, "First-year college students struggle with lack of sleep, good eating habits, and APA style" (Roberts, 2017, p. 199), and listed several solutions.

No page numbers . If the work does not have a page number, then provide an "address" to find the quoted text using one of the following methods:

• Supply a heading or section name (this can be abbreviated).                                                                    "Librarians are the keepers of information" (Johnson & Minchew, 2022, Reference Section)
• Supply a paragraph number (for unnumbered paragraphs count them accordingly).                                  "Reference is not a mute topic" (Johnson & Minchew, 2022, para. 1).
• Supply a heading or section name and a paragraph number.                                                                      "Research is a complex undertaking. Proper technique wields the best possible results" (Johnson & Minchew, 2022, Research section, para. 3).

Audiovisual work . When providing a quote directly from an audiovisual work ( audioBooks, films, podcast, TV programs, YouTube video ), place a time stamp for the beginning of the quote in lieu of a page number.

     "Books open the path to understanding and expanding our minds" (Johnson, 2022, 7:11).

• Annotated Sample Student Paper Here's a sample paper provided by APA. For every style rule, there is a comment highlighted in the paper that tells you where to find the discussion of the rule in the APA Style Manual.

APA follows an author and date of publication model for citing sources in your research paper and are presented as either narrative or parenthetical citations.  The formatting does not vary due to format type, however it may deviate from the norm due to factors such as: number of authors, organization instead of individual author, lack of author, or lack of date.  By providing the standard author and date within your paper, the reader will be able to link the information presented easily to the full citation provided in the reference list.

View examples and explanations on this page or visit the In Text Quick View for more examples.

APA encourages paraphrasing over using direct quotes.  Use direct quotes when:

• Reproducing an exact definition
• Author has said something memorably or succinctly
• When you want to respond to exact wording

When creating a citation for a direct quote, provide author, year and page number for both narrative and parenthetical citations.

Ex.  University of Southern California (2020) "direct quote from author" (p. 4)  OR  "direct quote from author" (University of Southern California, 2020, p. 4).

How to cite specific parts of a source:

Author named in text:

Social historian Richard Sennett (1980) names the tendency to come to terms with difficult experiences a "purification process" whereby "threatening or painful dissonances are warded off to preserve intact a clear and articulated image of oneself and one's place in the world" (p. 11).

Author named in parentheses:

The tendency to come to terms with difficult experiences is referred to as a "purification process" whereby "threatening or painful dissonances are warded off to preserve intact a clear and articulated image of oneself and one's place in the world" (Sennett, 1980, p. 11).

These examples © Duke University Libraries http://library.duke.edu/research/citing/within/apa.html

More than one way to cite:

Flynn (1999) stated in her treatise In a recent treatise on services (Flynn, 1999) In a 1999 treatise, Flynn stated

Subsequent references to same study in same paragraph:

In her treatise on services, Flynn (1999) stated her evaluative methods…Flynn also described

One work, multiple authors

When a work has two authors, always cite both authors' names in your text:

        Significant findings in a study of Los Angeles (McCroskey & O'Keefe, 2000)

When a citation has 3 or more authors, include the last name of the first author, followed by et al. (not italicized), and the year.

        (Nishimoto et al., 1998)

For narrative citations, use the word "and" to separate authors, for parenthetical citations, use an ampersand:

         McCroskey and O'Keefe (2000) studied Los Angeles...          (McCroskey & O'Keefe, 2000)

Groups as authors

First narrative citation: National Association of Social Workers (NASW, 1987)

Subsequent narrative citation: NASW (1987)

First text citation: (National Association of Social Workers [NASW], 1987)

Subsequent text citation: (NASW, 1987)

Works with no authors

Cite the work in your text using the first few words of the reference list entry (usually the title). Put double quotation marks around the title of an article or chapter, and italicize the title of a periodical, book, brochure or report:

The policy stated in the article (“Services for Disabled Children,” 1992)

The policy stated in the book Access to Services for Children (1995)

Specific parts of a source

Indicate the page, chapter, figure, table, or equation at the appropriate point in your text. Give page numbers for quotations, and use the abbreviations for the words page and chapter:

(Aranda & Knight, 1997, p. 344)

(Ell & Castaneda, 1998, chap. 5)

Personal communications

This format applies to emails, messages from nonarchived discussion groups, electronic bulletin boards, personal interviews, telephone conversations, etc. Do not list personal communications in your reference list as they are not recoverable by your reader. In your text, provide initials and surname of communicator and as exact a date as possible.

(M. Flynn, personal communication, September 20, 1999)

Sometimes you'll have multiple works by the same author in the same year. For instance, you may reference a number of tax documents from the same year, which would all be cited with (Internal Revenue Service, 2012).  So how do you differentiate?

In those instances, differentiate sources with a letter after the year. From the example above, the 990 form might be (Internal Revenue Service, 2012a) and the 1040 form would be (Internal Revenue Service, 2012b).  Just make sure the letters stay consistent in your reference list!

Sometimes, you will use a source that you didn't yourself read.  In those cases, the original source came from a secondary source you did read.  APA states that you should use secondary sources sparingly and may occur when "the original work is out of print, unavailable, or available only in a language that you do not understand."

When using secondary sources, indicate it by included "as cited in" as part of your in-text citation

Citing Dissertations & Theses in APA Format

Dissertations & Theses

Dissertations and theses are formatted the same way in APA 7th edition. Theses are generally the culminating work for a master's or undergraduate degree and dissertations are often original research completed by doctoral students. Here are examples of a dissertation & a thesis, and how they would be formatted: 

Examples: 

Dissertation found in Proquest Dissertations and Theses Global:

7th ed Citing Direct Quotations

Citations for direct quotations.

A direct quotation is a verbatim reproduction from another work. The APA recommends paraphrasing when possible. The format of the quotation and the in-text citation depends on the length of the quotation. The in-text citation will include the author, year, and page number(s). The page number format is different for single pages, a page range, and non-consecutive (discontinuous) pages. The APA formats direct quotations into short quotations (fewer than 40 words), and block quotations (40 words or more). 

Page Numbers

No Page Numbers? Check out the APA Style's section on Direct Quotation of Material Without Page Numbers This link opens in a new window . You can use section names, paragraph numbers, time stamps (for audiovisual works), and more. 

Short Quotations

Short quotations contain fewer than 40 words. To incorporate this type of quotation into your work enclose the words in quotation marks. Do not add an ellipsis unless one is used in source. Add a full in-text citation in the same sentence.

Parenthetical Citation

General Format

A parenthetical citation can be either immediately following the quotation or at the end of the sentence.

Text "quote" (Author, Year, Page).

Text "quote" (Author, Year, Page) more text.

For Example

Mental health care for veterans and active duty military needs to be greatly improved. One tool that is used is the Combat Exposure Scale (CES) this is a "seven-item self-report measure that assesses wartime stressors experienced by combatants" (Lawhorne-Scott et al., 2012, p. 36).

Narrative Citation

A narrative citation typically includes the author and year before the quotations and the page number(s) after the quotation.

Author (Year) text "quote" (Page).

However if the quote begins the sentence, the author will follow in a narrative form with the year and date in parentheses afterwards.

"Quote" text Author (Year, Page) more text.

Chen et al. (2019) noted that "an increased patient–nurse ratio would induce nurses’ intention to leave their job" (p. 12).

"Workforce staffing and scheduling for clinical units in healthcare system is a formidable challenge" wrote Sedeh (2018, p. 1) in their review of nurse staffing in emergency room departments.

Block Quotations

Block quotations contain 40 words or more. To incorporate this type of quotation into your work you will need to begin the quotation on a new line, indent the left margin for the entire quotation, and double-space the quotation. Add a full in-text citation either in the narrative while including the page numbers at the end after the quotation's final punctuation, or a parenthetical citation after the last punctuation.

A parenthetical citation is placed after the quote's final punctuation.

The symptoms of anxiety can be debilitating:

A narrative citation typically includes the author and year before the block quotation and the page number(s) immediately after the quotation's last punctuation.

Chen et al. (2019) detail how hospitals are in the business of saving lives and those in charge have a lot to take into account when planning their nurse-patient ratios:

A direct quotation reproduces word-for-word material taken directly from another author’s work, or from your own previously published work.

If the quotation is fewer than 40 words , incorporate it into your paragraph and enclose it in double quotation marks. 

David Copperfield starts with "Whether I shall turn out to be the hero of my own life, or whether that station will be held by anybody else, these pages must show" (Dickens, 1869, p. 1).

If the quotation comprises 40 or more words , include it in an indented, freestanding block of text, without quotation marks. Make it double spaced .

Whether I shall turn out to be the hero of my own life, or whether that station will be held by anybody else, these pages must show. To beginmy life with the beginning of my life, I record that I was born (as I have been informed and believe) on a Friday, at twelve o’clock at night. It was remarked that the clock began to strike, and I began to cry, simultaneously. (Dickens, 1896, p. 1)

• Include the author, year, and specific page number for that quotation.
• For material without page numbers, give the paragraph number or a time stamp.
• Include a complete reference in the reference list.

(Smith, 2003, p. 105)

(Brown, 1999, pp. 49-50)

Smith (2003) has argued that "......" (p. 105)

As Brown (1999) found "......" (pp. 49-50) 

(Anderson, 2019, 2:17)

Anderson (2019) noted that "...." (2:17)

Direct quotes that are less than 40 words

Parenthetical reference.

• Can be added either directly after the quote or at the end of the sentence.
• Ensure it is the same sentence as the quote.

Mindfulness has a range of meanings as it "has become a trend word conveying a diversity of understandings dependent on context" (Crane, 2017, p. 586).

Mindfulness has a range of meanings as it "has become a trend word conveying a diversity of understandings dependent on context" (Crane, 2017, p. 586) and can encompass...

Narrative reference

• Add the author in the sentence, followed by the year in brackets. Include the page number in brackets after the quote.

As Crane (2017) said, "Mindfulness has become a trend word conveying a diversity of understandings dependent on context" (p. 586).

As Crane (2017) said, "Mindfulness has become a trend word conveying a diversity of understandings dependent on context" (p. 586) and can encompass....

Quotes with more than 40 words (block quotes)

• Include at the end of the quote.

Whether I shall turn out to be the hero of my own life, or whether that station will be held by anybody else, these pages must show. To begin my life with the beginning of my life, I record that I was born (as I have been informed and believe) on a Friday, at twelve o’clock at night. It was remarked that the clock began to strike, and I began to cry, simultaneously. (Dickens, 1896, p. 1)

• Include the author last name in the sentence, followed by the year in brackets before the block quote.
• Add the page number in brackets at the end of the block quote.

As Dickens (1896) famously began "David Copperfield":

Whether I shall turn out to be the hero of my own life, or whether that station will be held by anybody else, these pages must show. To begin my life with the beginning of my life, I record that I was born (as I have been informed and believe) on a Friday, at twelve o’clock at night. It was remarked that the clock began to strike, and I began to cry, simultaneously. (p. 1)

• Add a time stamp in place of a page number when quoting from audiovisual works such as videos, songs, TV shows.

(Yates, 2019, 1:14)

(Henderson, 2017, 2:30:14)

For works without a page number, you can add:-

• paragraph number (manually count if not listed) eg. (Kennedy, 2019, para.8)
• heading or section name eg. (Harris, 2018, Behaviour Therapy section)
• act, scene and line(s) for plays eg. (Wilde, 1895/1997, 1.1.6-8) (means Act 1.Scene 1.Line(s) 6-8)
• canonically numbered sections for religious or classical works eg. (Genesis 15:6) (include book, chapter, verse, line or canto in place of page number)

• Use 'p.' for a single page number ( Example: p. 15) and 'pp.' for multiple page numbers ( Example: pp. 125-126).
• If citing a source without page numbers, cite the paragraph number ( Example: para. 4) or other identifying information ( Example:  Slide 7, Table 2, Results section).  
• You can cite your information as part of the sentence (called a narrative citation) or at the end in parentheses (known as a parenthetical citation).
• If you have two or more authors, use the word 'and' for narrative citations and '&' for parenthetical citations 
• If you have three or more authors, use 'et al.' after the first authors last name to indicated there are additional authors. 
• If you are quoting sources with embedded citations, include them in the quote but you do not need to cite the embedded citations in your reference page (only the source your are quoting).  
• If you are quoting material with quotations marks, use double quotation marks to indicate the quote and change the quotations marks in the quote to a single quotation mark.

Single Author:  Simmons (2019) points out, "Even with airtight routines and procedures in place, you will have students who engage in inappropriate behaviors" (p. 46). 

Two Authors:  Orben and Przybylski (2019) noted that “until they are displaced by a new technological innovation, digital screens will remain a fixture of human experience” (p. 694).

Three or more Authors: Larson et al. (2018) stated, "another potential alternative might involve a creative merger of electronic media and outdoor time to promote nature connection" (p. 982). 

Narrative Direct Quotation With an Embedded Source:  Larson et al. (2018) points out, "However, though they did not assess broader outdoor time, Kellert et al. (2017) found no discernible differences among boys’ and girls’ nature-based recreation" (p. 968). 

Note: Larson et al. would be cited in your reference page but not Kellert et al. as that is the embedded source. 

 Parenthetical Direct  Quotation With Page Numbers 

When citing multiple authors after a quotation, the ampersand symbol '&' is used instead of the word 'and'.

In-Text Citation Basics

Author/Date Citation Method

APA publications use the author/date in text citation system to briefly identify sources to readers.  Each in-text citation is listed alphabetically in the reference list.  All in-text citations referenced in the body of work musr appear in the reference list and vice versa.

The author-date method includes the author's surname and the the publication year.  Do not include suffixes such as Jr., Esq., etc.

(Jones, 2009)

The author/date method is also used with direct quotes.  Another component is added in this format:

(Jones, 2009, p.19)

When multiple pages are referenced, use pp.

(Jones, 2009, pp.19-21)

Variations of author/date within a sentence

Here are some examples of how the author/date citation method are formatted within different parts of a sentence. Please note the author, publication date, and study are entirely fictional (see APA, p.174).

Beginning of a sentence:

Jones (2009) completed a study on the effects of dark chocolate on heart disease.

Middle of a sentence:

In 2009, Jones's study on the effects of dark chocolate and heart disease revealed...

End of a sentence:

The study revealed that participants who ate dark chocolate bars every day did not develop heart disease (Jones, 2009).

Citing a specific part of source (chapter, tables, figures, or equations)

When citing a particular part of a source, it is important to indicate the page, chapter, figure, table, or equation.  Remember to always give page numbers for direct quotations (see APA, section 6.19, p. 179). 

Correct abbreviations continue to be used (see APA, sections 4.22 - 4.30).

(National Chocolate Lovers Association, 2007, p.17)

(Jones, 2009, Chapter 8)

Paraphrasing

Paraphrasing is great because it allows you to use your own words and your own voice.  It demonstrates that you truly understand what the author is saying. Word of caution: Avoid changing the author's meaning and/or plagiarizing the author.  Looking up certain words within the thesaurus is not paraphrasing.  It is also important to cite the author while paraphrasing.

Here is an example of paraphrasing:

Original citation:

"With rates of childhood obesity climbing over the last decade, some parents and policy-makers have thought to consider whether the availability of endless soda and junk food in school vending machines might be contributing to the problem—and if banning those foods in schools might help solve it" (Price, 2012).

Paraphrase:

Price discusses the possibility that the availability of unhealthy, sugary snacks and drinks in school vending machines has contributed to the rising epidemic of obesity in children.  In an effort to eliminate the source of the problem, some of have proposed implementing a ban (2012).

Direct Quotes: the Short and Long

Direct quotations are sometimes necessary to truly convey the author's meaning to the reader.  When directly quoting an author(s),  (a) the quote must be relevant to your argument, (b) it needs to smoothly transition between what comes first and move to what comes later, (c), it must fit logically and make grammatical sense, and (d) it should be no longer than absolutely necessary.

When reproducing an author's word directly, it is extremely important to quote and cite.  Direct quotations with citation prevents plagiarism and gives the author credit for his/her work. The parenthetical cite should always contain the author's surname, the publication year of the work, and the page citation or paragraph number (for nonpaginated material).

Direct quotations can vary in length.  Quotes fewer than 40 words should be incorporated into the text of the paragraph.  Quotes comprised of 40 or more words, need to be formatted in block quotes.  (see APA, section 6.03, pp.170 - 173; and APA Style Blog , "How to Cite Direct Quotations" or APA Style Blog , "You Can Quote Me on This").

Short, direct quotes (less than 40 words):

Author and quote separated

Bell and Shank (2007) identify that "[a]t least one survey identified library instruction as the type of collaboration mentioned most frequently by librarians" (p.67).

Article retrieved online (see APA, section 6.05, p.171-172)

Price (2012) notes "[t]he results aren't huge, but apparently these laws have a real—and positive—effect on students' health" (para.4).

Author and quote together

"Design is designed in many ways.  By one definition it is the conscious examination of objects and processes to determine how they can be made better" (Bell & Shank, 2007, p. 23).

" The books, sold in the United States, share a piece of a foreign culture, while profits are put back into the country the story came from" (Anthony, 2012, para. 2).

Long, block quotes (40 words or more):

Formatting rules:

• Indent the block quote five spaces or half an inch. • Do not use quotation marks. • Double space the quote unless your school has a rule about single spacing block quotes. • Do not include any additional lines or spaces before or after the block quote. • Notice that in block quotes, the period goes before the parentheses, not after.

Michelli (2007) uses the coffee chain, Starbucks, as example on how to become extraordinary.  He discusses in detail various principles he discovered during his research on the renowned company.  One of the principles focuses on "making it your own."  He writes,

Like most companies, Starbucks has wrestled with ways to invite its partners to fully engage their passions and talents everyday in every interaction at wor.  Simultaneously, the leadership has to ensure that individual partners' differences are blending into a generally uniform experience for customers.  Finding a balance between these two important, yet somtimes divergent, leadership responsibilities can be awkward.  Yet through its principle of Make It Your Own, Starbucks has succeeded in creating a unique model that encourages partners at all levels to pour their creative energy and dedication into everything they do. (p. 20)

This principle does not only apply to businesses; it can be part of anyone's personal beliefs.

If you are quoting someone word-for-word or using someone else's ideas or statistics in your writing, you will need to reference it within the body of your work. Work the author’s surname or organisation’s name, the year of publication and the page number into the paragraph you are writing. The purpose is to give basic details so your reader can get more information from the list at the end.

Example 1: 'In the food and beverage industry, it is estimated that 25 percent of employees steal regardless of the controls in place' (Walker 2011, p. 222). Example 2: Walker (2011, p. 222) states that 'in the food and beverage industry, it is estimated that 25 percent of employees steal regardless of the controls in place'. Example 3: In his 2011 text, Walker states that 'in the food and beverage industry, it is estimated that 25 percent of employees steal regardless of the controls in place' (p. 222). Note that page numbers are only necessary for in text citations when direct quotes or precise information is used. Direct quotations  

•    should be used sparingly in an assignment
•    can be used if you need to record exact words or phrases
•    are useful if you find some writing which expresses exactly what you want to say very well
•    can be a phrase, a short sentence, or longer

Small quotations  (less than 30 words)are included in your writing with the text in single quote marks: The pearl has been 'a particularly potent literary device' (Joyce & Addison 1992, p. 15) in many cultures from ancient times. If the quotation is longer than 30 words, set it out like this: The post-war years were not a time of great innovation.  As Ewing (2001, p. 167) states:    To get back to normal, which meant to order and stability, was the general longing and fashion voiced this conservative mood in a series of smooth, well-balanced lines, embodied in clothes of notable elegance, carefully designed, well-made and flattering. OR The post-war years were not a time of great innovation:      To get back to normal, which meant to order and stability, was the general longing and fashion voiced this conservative mood in a series of smooth, well-balanced lines, embodied in clothes of notable elegance, carefully designed, well-made and flattering.  (Ewing 2001, p. 167) Points to remember for longer quotes:  

• place a colon (:) at the end of your writing before the quote
• leave a space of one line before and after the quotation
• do not use quotation marks around the quotation
• use a smaller font for the quote, e.g. if your assignment is in 12, use 10 for the quotation
• indent the quote
• if your assignment is in double spacing, keep the quote in single spacing

Citing Someone Else's Quotation

Sometimes an author will cite another author and you may want to use this in your assignment.  Care needs to be taken with quotations and citations taken out of context.  It is a good idea to try to track down the original work.  If you are not able to find the original work, you may still use a quotation from or a reference to the cited work, making sure that you acknowledge both of the authors.

Original text:

'Although Barnes sees the mods as a male-dominated youth culture (Barnes, 1991: p.8), Garber and McRobbie argue that the mods were the first 'softer' working-class subculture, in which girls could participate more openly and directly (Garber & Mc Robbie, 1979: p.226).'

In-text citation:

Some writers disagree with the idea that the mods were a male dominated subculture (Garber & McRobbie 1979, p. 226 in Jenss 2005, p. 192).

Garber & McRobbie (1979 p. 226 in Jenss 2005, p. 192) claim that the mods were one of the first youth subcultures in which girls could participate more fully.

Reference list:

Jenss, H. 2005, 'Sixties dress only!', in A. Palmer & H. Clark (eds), Old clothes, new looks: second hand fashion, Berg Publishers, Oxford.

Personal Communications

References to personal communications such as letters, emails, interviews, or phone conversations can be included in assignments. The in-text citation should have the author's surname followed by their initials, then the abbreviation pers. comm. and the date. These citations should  not be included in the Reference List/Bibliography.

The patient valued the knowledge and experience of other cancer patients more than medical information ( Wilson, P. 2013, pers. comm., September 10).

When interviewed, Susan Jones said she halted her information seeking because of fearful and contradictory information (Jones, S. 2013, pers. comm., September 28).

Information From More Than One Source

If you include the authors in the sentence, they are listed in chronological order by year of publication in brackets.

If the author's names are not included in the sentence, they are enclosed together in one set of brackets and presented chronologically, starting with the first published. A semi-colon is inserted after each citation of the author and year of publication.

Morrow & Young (1996), Irish & Parsons (2016) and Elish-Piper (2017) all stress the importance of parent participation in children's literacy development. 

Previous research has found that parents play a key role in their children's literacy development and school success (Morrow & Young, 1996; Irish & Parsons, 2016; Elish-Piper, 2017).

Using Abbreviations

If you are referring numerous times to an organisation with a long title, you may use the relevant acronym or initialism. The first time you refer to the organisation, include both the full title and, in parentheses (round brackets), the acronym or initialism. Thereafter, the acronym or initialism will suffice. Both acronyms and initialisms are written without full stops .

Example in text :

The Royal Society for the Prevention of Cruelty to Animals (RSPCA) has a policy on removing injured animals. The RSPCA is permitted to enter a property at any time following a report of complaint (RSPCA 2006).

In the reference list, both the long title and the acronym or initialism must be included. For example:

Royal Society for the Prevention of Cruelty to Animals (RSPCA) 2006, Policy statement on removal of animals at risk , RSPCA, Brisbane.

Israel-Gaza war

The Israel-Gaza war has gone on for six months, and tensions have spilled into the surrounding region .

The war: On Oct. 7, Hamas militants launched an unprecedented cross-border attack on Israel that included the taking of civilian hostages at a music festival . (See photos and videos of how the deadly assault unfolded ). Israel declared war on Hamas in response, launching a ground invasion that fueled the biggest displacement in the region since Israel’s creation in 1948 .

Gaza crisis: In the Gaza Strip, Israel has waged one of this century’s most destructive wars , killing tens of thousands and plunging at least half of the population into “ famine-like conditions. ” For months, Israel has resisted pressure from Western allies to allow more humanitarian aid into the enclave .

U.S. involvement: Despite tensions between Israeli Prime Minister Benjamin Netanyahu and some U.S. politicians , including President Biden, the United States supports Israel with weapons , funds aid packages , and has vetoed or abstained from the United Nations’ cease-fire resolutions.

History: The roots of the Israeli-Palestinian conflict and mistrust are deep and complex, predating the establishment of the state of Israel in 1948 . Read more on the history of the Gaza Strip .

Title: tango 2: aligning diffusion-based text-to-audio generations through direct preference optimization.

Abstract: Generative multimodal content is increasingly prevalent in much of the content creation arena, as it has the potential to allow artists and media personnel to create pre-production mockups by quickly bringing their ideas to life. The generation of audio from text prompts is an important aspect of such processes in the music and film industry. Many of the recent diffusion-based text-to-audio models focus on training increasingly sophisticated diffusion models on a large set of datasets of prompt-audio pairs. These models do not explicitly focus on the presence of concepts or events and their temporal ordering in the output audio with respect to the input prompt. Our hypothesis is focusing on how these aspects of audio generation could improve audio generation performance in the presence of limited data. As such, in this work, using an existing text-to-audio model Tango, we synthetically create a preference dataset where each prompt has a winner audio output and some loser audio outputs for the diffusion model to learn from. The loser outputs, in theory, have some concepts from the prompt missing or in an incorrect order. We fine-tune the publicly available Tango text-to-audio model using diffusion-DPO (direct preference optimization) loss on our preference dataset and show that it leads to improved audio output over Tango and AudioLDM2, in terms of both automatic- and manual-evaluation metrics.

arXivLabs is a framework that allows collaborators to develop and share new arXiv features directly on our website.

Both individuals and organizations that work with arXivLabs have embraced and accepted our values of openness, community, excellence, and user data privacy. arXiv is committed to these values and only works with partners that adhere to them.
