Using In-text Citation

Include an in-text citation when you refer to, summarize, paraphrase, or quote from another source. For every in-text citation in your paper, there must be a corresponding entry in your reference list.

APA in-text citation style uses the author's last name and the year of publication, for example: (Field, 2005). For direct quotations, include the page number as well, for example: (Field, 2005, p. 14). For sources such as websites and e-books that have no page numbers , use a paragraph number, for example: (Field, 2005, para. 1). More information on direct quotation of sources without pagination is given on the APA Style and Grammar Guidelines web page.

Example paragraph with in-text citation

A few researchers in the linguistics field have developed training programs designed to improve native speakers' ability to understand accented speech (Derwing et al., 2002; Thomas, 2004). Their training techniques are based on the research described above indicating that comprehension improves with exposure to non-native speech.   Derwing et al. (2002) conducted their training with students preparing to be social workers, but note that other professionals who work with non-native speakers could benefit from a similar program.

Thomas, H. K. (2004).  Training strategies for improving listeners' comprehension of foreign-accented speech  (Doctoral dissertation). University of Colorado, Boulder.

Citing Web Pages In Text

Cite web pages in text as you would any other source, using the author and date if known. Keep in mind that the author may be an organization rather than a person. For sources with no author, use the title in place of an author.

For sources with no date use n.d. (for no date) in place of the year: (Smith, n.d.). For more information on citations for sources with no date or other missing information see the page on missing reference information on the APA Style and Grammar Guidelines web page. 

Below are examples of using in-text citation with web pages.

Web page with author:

General Guidelines

In-text references should immediately follow the title, word, or phrase to which they are directly relevant, rather than appearing at the end of long clauses or sentences. In-text references should always precede punctuation marks. Below are examples of using in-text citation.

Author's name in parentheses:

One study found that the most important element in comprehending non-native speech is familiarity with the topic (Gass & Varonis, 1984).

Author's name part of narrative:

Gass and Varonis (1984) found that the most important element in comprehending non-native speech is familiarity with the topic.

Group as author: First citation: (American Psychological Association [APA], 2015) Subsequent citation: (APA, 2015)

Multiple works: (separate each work with semi-colons)

Research shows that listening to a particular accent improves comprehension of accented speech in general (Gass & Varonis, 1984; Krech Thomas, 2004).

Direct quote: (include page number and place quotation marks around the direct quote)

One study found that “the listener's familiarity with the topic of discourse greatly facilitates the interpretation of the entire message” (Gass & Varonis, 1984, p. 85).

Gass and Varonis (1984) found that “the listener’s familiarity with the topic of discourse greatly facilitates the interpretation of the entire message” (p. 85).

Note:  For direct quotations of more than 40 words , display the quote as an indented block of text without quotation marks and include the authors’ names, year, and page number in parentheses at the end of the quote. For example:

This suggests that familiarity with nonnative speech in general, although it is clearly not as important a variable as topic familiarity, may indeed have some effect. That is, prior experience with nonnative speech, such as that gained by listening to the reading, facilitates comprehension. (Gass & Varonis, 1984, p. 77)

Works by Multiple Authors

APA style has specific rules for citing works by multiple authors. Use the following guidelines to determine how to correctly cite works by multiple authors in text. For more information on citing works by multiple authors see the APA Style and Grammar Guidelines page on in-text citation .

Note: When using multiple authors' names as part of your narrative, rather than in parentheses, always spell out the word and. For multiple authors' names within a parenthetic citation, use &.

One author: (Field, 2005)

Two authors: (Gass & Varonis, 1984)

Three or more authors:   (Tremblay et al., 2010)

There are two basic ways to cite someone's work in text.

In narrative citations , the authors are part of the sentence - you are referring to them by name. For example:

Becker (2013) defined gamification as giving the mechanics of principles of a game to other activities.

Cho and Castañeda (2019) noted that game-like activities are frequently used in language classes that adopt mobile and computer technologies.

In parenthetical citations , the authors are not mentioned in the sentence, just the content of their work. Place the citation at the end of the sentence or clause where you have used their information. The author's names are placed in the brackets (parentheses) with the rest of the citation details:

Gamification involves giving the mechanics or principles of a game to another activity (Becker, 2013).

Increasingly, game-like activities are frequently used in language classes that adopt mobile and computer technologies (Cho & Castañeda, 2019).

Using references in text

For APA, you use the authors' surnames only and the year in text. If you are using a direct quote, you will also need to use a page number.

Narrative citations:

If an in-text citation has the authors' names as part of the sentence (that is, outside of brackets) place the year and page numbers in brackets immediately after the name, and use 'and' between the authors' names:  Jones and Smith (2020, p. 29)

Parenthetical citations:

If an in-text citation has the authors' names in brackets use "&" between the authors' names :  (Jones & Smith, 2020, p. 29).

Note: Some lecturers want page numbers for all citations, while some only want page numbers with direct quotes. Check with your lecturer to see what you need to do for your assignment. If the direct quote starts on one page and finishes on another, include the page range (Jones & Smith, 2020, pp. 29-30).

1 author

Smith (2020) found that "the mice disappeared within minutes" (p. 29).

The author stated "the mice disappeared within minutes" (Smith, 2020, p. 29).

Jones and Smith (2020) found that "the mice disappeared within minutes" (p. 29).

The authors stated "the mice disappeared within minutes" (Jones & Smith, 2020, p. 29).

For 3 or more authors , use the first author and "et al." for all in-text citations

Green et al.'s (2019) findings indicated that the intervention was not based on evidence from clinical trials.

It appears the intervention was not based on evidence from clinical trials (Green et al., 2019).

If you cite more than one work in the same set of brackets in text , your citations will go in the same order in which they will appear in your reference list (i.e. alphabetical order, then oldest to newest for works by the same author) and be separated by a semi-colon. E.g.:

• (Corbin, 2015; James & Waterson, 2017; Smith et al., 2016).
• (Corbin, 2015; 2018)
• (Queensland Health, 2017a; 2017b)
• Use only the   surnames   of your authors   in text   (e.g., Smith & Brown, 2014) - however, if you have two authors with the same surname who have published in the same year, then you will need to use their initials to distinguish between the two of them (e.g., K. Smith, 2014; N. Smith, 2014).   Otherwise, do not use initials in text .

If your author isn't an "author".

Whoever is in the "author" position of the refence in the references list is treated like an author in text. So, for example, if you had an edited book and the editors of the book were in the "author" position at the beginning of the reference, you would treat them exactly the same way as you would an author - do not include any other information. The same applies for works where the "author" is an illustrator, producer, composer, etc.

• Summarising
• Paraphrasing

It is always a good idea to keep direct quotes to a minimum. Quoting doesn't showcase your writing ability - all it shows is that you can read (plus, lecturers hate reading assignments with a lot of quotes).

You should only use direct quotes if the exact wording is important , otherwise it is better to paraphrase.

If you feel a direct quote is appropriate, try to keep only the most important part of the quote and avoid letting it take up the entire sentence - always start or end the sentence with your own words to tie the quote back into your assignment. Long quotes (more than 40 words) are called "block quotes" and are rarely used in most subject areas (they mostly belong in Literature, History or similar subjects). Each referencing style has rules for setting out a block quote. Check with your style guide .

It has been observed that "pink fairy armadillos seem to be extremely susceptible to stress" (Superina, 2011, p. 6).

NB! Most referencing styles will require a page number to tell readers where to find the original quote.

It is a type of paraphrasing, and you will be using this frequently in your assignments, but note that summarising another person's work or argument isn't showing how you make connections or understand implications. This is preferred to quoting, but where possible try to go beyond simply summarising another person's information without "adding value".

And, remember, the words must be your own words . If you use the exact wording from the original at any time, those words must be treated as a direct quote.

All information must be cited, even if it is in your own words.

Superina (2011) observed a captive pink fairy armadillo, and noticed any variation in its environment could cause great stress.

NB! Some lecturers and citation styles want page numbers for everything you cite, others only want page numbers for direct quotes. Check with your lecturer.

Paraphrasing often involves commenting about the information at the same time, and this is where you can really show your understanding of the topic. You should try to do this within every paragraph in the body of your assignment.

When paraphrasing, it is important to remember that using a thesaurus to change every other word isn't really paraphrasing. It's patchwriting , and it's a kind of plagiarism (as you are not creating original work).

Use your own voice! You sound like you when you write - you have a distinctive style that is all your own, and when your "tone" suddenly changes for a section of your assignment, it looks highly suspicious. Your lecturer starts to wonder if you really wrote that part yourself. Make sure you have genuinely thought about how *you* would write this information, and that the paraphrasing really is in your own words.

Always cite your sources! Even if you have drawn from three different papers to write this one sentence, which is completely in your own words, you still have to cite your sources for that sentence (oh, and excellent work, by the way).

Captive pink fairy armadillos do not respond well to changes in their environment and can be easily stressed (Superina, 2011).

NB! Some lecturers and citation styles want page numbers for all citations, others only want them for direct quotes. Check with your lecturer.

Excerpt from "The Big Fake Essay"

You can read the entire Big Fake Essay on the Writing Guide. It includes more details about academic writing and the formatting of essays.

• The Big Fake Essay
• Academic Writing Workshop

When you have multiple authors with the same surname who published in the same year:

If your authors have different initials, then include the initials:

As A. Smith (2016) noted...

...which was confirmed by J.G. Smith's (2016) study.

(A. Smith, 2016; J. G. Smith, 2016).

If your authors have the same initials, then include the name:

As Adam Smith noted...

...which was confirmed by Amy Smith's (2016) study.

(Adam Smith, 2016; Amy Smith, 2016).

Note: In your reference list, you would include the author's first name in [square brackets] after their initials:

Smith, A. [Adam]. (2016)...

Smith, A. [Amy]. (2016)...

When you have multiple works by the same author in the same year:

In your reference list, you will have arranged the works alphabetically by title (see the page on Reference Lists for more information). This decides which reference is "a", "b", "c", and so on. You cite them in text accordingly:

Asthma is the most common disease affecting the Queensland population (Queensland Health, 2017b). However, many people do not know how to manage their asthma symptoms (Queensland Health, 2017a).

When you have multiple works by the same author in different years:

Asthma is the most common disease affecting the Queensland population (Queensland Health, 2017, 2018). 

When you do not have an author, and your reference list entry begins with the title:

Use the title in place of the author's name, and place it in "quotation marks" if it is the title of an article or book chapter, or in italics if the title would go in italics in your reference list:

During the 2017 presidential inauguration, there were some moments of awkwardness ("Mrs. Obama Says ‘Lovely Frame’", 2018).

Note: You do not need to use the entire title, but a reasonable portion so that it does not end too abruptly - "Mrs. Obama Says" would be too abrupt, but the full title "Mrs. Obama Says 'Lovely Frame' in Box During Awkward Handoff" is unecessarily long. You should also use title case for titles when referring to them in the text of your work.

If there are no page numbers, you can include any of the following in the in-text citation:

• "On Australia Day 1938 William Cooper ... joined forces with Jack Patten and William Ferguson ... to hold a Day of Mourning to draw attention to the losses suffered by Aboriginal people at the hands of the whiteman" (National Museum of Australia, n.d., para. 4).
• "in 1957 news of a report by the Western Australian government provided the catalyst for a reform movement" (National Museum of Australia, n.d., The catalyst for change section, para. 1)
• "By the end of this year of intense activity over 100,000 signatures had been collected" (National Museum of Australia, n.d., "petition gathering", para. 1).

When you are citing a classical work, like the Bible or the Quran:

References to works of scripture or other classical works are treated differently to regular citations. See the APA Blog's entry for more details:

Happy Holiday Citing: Citation of Classical Works . (Please note, this document is from the 6th edition of APA).

In text citation:

If the name of the organisation first appears in a narrative citation, include the abbreviation before the year in brackets, separated with a comma. Use the official acronym/abreviation if you can find it. Otherwise check with your lecturer for permission to create your own acronyms.

Australian Bureau of Statistics (ABS, 2013) shows that...

The Queensland Department of Education (DoE, 2020) encourages students to... (please note, Queensland isn't part of the department's name, it is used in the sentence to provide clarity)

If the name of the organisation first appears in a citation in brackets, include the abbreviation in square brackets.

(Australian Bureau of Statistics [ABS], 2013)

(Department of Education [DoE], 2020)

In the second and subsequent citations, only include the abbreviation or acronym

ABS  (2013) found that ...

DoE (2020) instructs teachers to...

This is disputed ( ABS , 2013).

Resources are designed to support "emotional learning pedagogy" (DoE, 2020)

In the reference list:

Use the full name of the organisation in the reference list.

Australian Institute of Health and Welfare. (2017).  Australia's welfare 2017 . https://www.aihw.gov.au/reports/australias-welfare/australias-welfare-2017/contents/table-of-contents

Department of Education. (2020, April 22). Respectful relationships education program . Queensland Government. https://education.qld.gov.au/curriculum/stages-of-schooling/respectful-relationships

Academically, it is better to find the original source and reference that.

If you do have to quote a secondary source:

• In the text you must cite the original author of the quote and the year the original quote was written as well as the source you read it in. If you do not know the year the original citation was written, omit the year.
• In the reference list you only list the source that you actually read.

Wembley (1997, as cited in Olsen, 1999) argues that impending fuel shortages ...

Wembley claimed that "fuel shortages are likely" (1997, as cited in Olsen, 1999, pp. 10-12).

Some have noted that fuel shortages are probable in the future (Wembley, 1997, as cited in Olsen, 1999).

What Is In-Text Citation?

In APA, in-text citations are inserted in the text of your research paper to briefly document the source of your information. Brief in-text citations point the reader to more complete information in the Reference list.

When using APA format, follow the author-date method of in-text citation. In the author-date method, the writer includes the author and date within the body of the paper and includes a corresponding reference in the Reference list. This method allows the reader to identify sources used in the paper by reviewing the author and date within the text of the paper, and then easily locate the corresponding reference in the alphabetical Reference list.

Create an in-text citation whenever you quote another work, or whenever you paraphrase another work in your own words.

In-text Citations Have Two Formats

• Parenthetical - the author name and publication date (or equivalent information) appear in parentheses. For example: Falsely balanced news coverage can distort the public's perception of expert consensus on an issue (Burnside, 2016).
• Narrative - the author name appears in running text and the date appears in parentheses immediately after the author name. For example: Burnside (2016) noted the dangers of falsely balanced news coverage.

If you are referring to an idea from another work (paraphrasing or summarizing) but NOT directly quoting the material, you only have to make reference to the author and year of publication and not the page number in your in-text reference.

If you are directly quoting or borrowing from another work, you should include the page number at the end of the parenthetical citation. For example, (Burnside, 2016, p. 199).

In-Text Citation Styles

The table below shows several examples of parenthetical and narrative citations.

Paraphrasing and Quoting: What Is the Difference?

There are two ways to integrate sources into your assignment:

• Paraphrasing  is used to show that you understand what the author wrote. You must reword the passage, expressing the ideas in your own words, and not just change a few words here and there. Make sure to also include an in-text citation.
• Quoting is copying a selection from someone else's work, phrasing it exactly as it was originally written. When quoting, place quotation marks (" ") around the selected passage to show where the quote begins and where it ends. Make sure to include an in-text citation.

Signal Phrases

If you refer to the author's name in a sentence, you do not have to include the name again as part of your in-text citation; instead, include the date after the name and the page number (if there is one) at the end of the quotation or the paraphrased section. For example:

Hunt (2011) explains that mother-infant attachment has been a leading topic of developmental research since John Bowlby found that "children raised in institutions were deficient in emotional and personality development" (p. 358).

Short Quotations

If a quotation consists of fewer than 40 words , treat it as a short quotation:

• Incorporate the quote into the text and enclose it within double quotation marks.
• Include the author, year of publication, and page number for the reference.
• For example, Smith (2019) demonstrated how to "..." (p. 112).
• For example, "..." (Smith, 2019, p. 112).

Long (Block) Quotations

If a quotation contains 40 words or more , treat it as a long (block) quotation:

• Do not use quotation marks to enclose a block quotation.
• Start a block quotation on a new line and indent the whole block 0.5 inches from the left margin.
• If there are additional paragraphs within the quotation, indent the first line of each subsequent paragraph an additional 0.5 inches.
• Double-space the entire block quotation; do not add extra space before or after it.
• Either (1) cite the source in parentheses after the quotation's final punctuation, or (2) cite the author and year in the narrative before the quotation and place only the page number in parentheses after the quotation's final punctuation. Do NOT add a period after the closing parenthesis in either case.
• See section 8.27 in the Publication Manual for examples of the block quotation.

Direct Quotation Without Page Numbers

When you quote from electronic sources that do not provide page numbers (e.g., webpages, websites, some e-books), provide readers with another way of locating the quoted passage. Use any of the following approaches that will best help readers find the quotation:

• Provide a heading or a section name.
• Provide a paragraph number (count the paragraphs manually if they are not numbered).
• Provide a heading or section name in combination with a paragraph number.

In-Text Citation for More than One Source

If you would like to cite more than one source within the same in-text citation, simply record the in-text citations as normal and separate them with a semi-colon. List the sources alphabetically by author's last name or first word used from the title if no author is given, in the same order they would appear in the Reference list. For example:

(Jones, 2015; Smith, 2014). 

( Beckworth, 2016;  "Nursing,"  2015).

In-text Citation Introduction

What is an in-text citation.

In APA Style, an in-text citation tells the reader where you got any and all information that did not come from inside your own head.  This is more obvious when you are directly quoting from a source, but it is also needed when you have summarized or paraphrased from a source and even if you got an idea from somewhere else.  In order to avoid plagiarism, it is extremely important that you cite all the words and ideas that you got from somewhere else. To learn more about plagiarism and how to avoid it, see Ethically Use Sources   and Plagiarism guidance from APA.

When citing sources in an APA Style paper, APA uses the author-date citation system. In this system, the writer includes the author and date within the body of the paper and includes a corresponding reference in the reference list. This citation system allows the reader to identify sources used in the paper by reviewing the author and date within the text of the paper, and then easily locate the corresponding reference in the alphabetical reference list. 

 There are two types of in-text citations that are used within the body of an APA paper to help the reader locate the corresponding reference in the reference list. T he two types of in-text citations are  parenthetical citations and narrative citations . A narrative citation is a type of citation where the author's name is used within the text of the sentence; whereas, a parenthetical citation is a type of citation where the author and date are in parentheses at the end of the sentence.   

How do I create narrative or parenthetical citations?

In  APA Style, cite your sources by putting the information about the source in parentheses at the end of a sentence or in the text of your paper as opposed to a footnote where the source information is at the bottom of the page or an endnote where it goes at the end of your paper.  There are slight differences depending on which style you are using.

Give the author’s last name and the publication year.

Only use page numbers or paragraph numbers for a direct quote.

Make sure the source information in parentheses matches with your reference in the reference list. 

The punctuation for the sentence goes AFTER the parentheses.

For a quote less than forty words  put quotation marks around the quoted words. For sources with designated page numbers - if the author and date are introduced in the sentence as a narrative citation, then add the page number in parentheses at the end of the quote. If the source does not have designated page numbers, then add the paragraph number, heading, or a combination of both the heading and paragraph number. If the author and date are not introduced as part of the text, then include the author and date with the page or paragraph number. The period should come after the parentheses.

If your quote is more than forty words , set it off in a block text by beginning the block quote on a new line, indent 0.5 inches (one-half), and do not add quotation marks around the block quote.  At the end of the quote put the period after the last word of the sentence followed by the parentheses. For more information, see Block Quote .

Basic In-Text Citation Styles

The basic in-text citation style for adding sources to the body of an APA style paper is to add the author and the date. There are a number of ways that can be done to aid in the readability and flow of the paper. However, the basic style for different authors types are listed in the table below.

Copyright 2020 by the American Psychological Association.  * Define the abbreviation for a group author only once in the text, choosing either the parenthetical or narrative citation. Once introduced, use only the abbreviation for all mentions of the group author in the text of your paper.

In-text Citation Examples

There are a number of ways that parenthetical and narrative citations can be added to the body of an APA style paper. Using variety helps with the readability and flow of the paper. The following table provides a few examples of common ways parenthetical and narrative citations are used for quotes and paraphrases.

Missing Citation Information

Q: I’m using a section of a website for one of my sources. How do I find out who the author is?

A: Here are a few places you will often find authors and dates of webpages:

• Bottom of the page (scroll all the way down) - but be wary of a copyright date that is the same on every page (it's better to use n.d. for "no date" in that case).
• In the “Contact” or “About Us” sections
• Go to the root or home page.
• Keep in mind that the author could be an organization rather than a person.

Example for navigating to the root or home page:

If you are at this page: https://identify.whatbird.com/obj/617/overview/Green-tailed_Towhee.aspx

Try going to this page: https://identify.whatbird.com/

Q: What if I still cannot find an author or a date?

A: If you still cannot find an author, cite the resource by its title in your references list. For your in-text citation, you will use a shortened version of the title instead of the author’s last name.

See the Purdue OWL example for "Unknown Author" here.

For a source with an unknown date, use the abbreviation “n.d.” instead of the date. (It stands for “no date.”)

Q: What if my source has no page numbers (like an electronic source)?

A: If you are directly quoting a source that is lacking page numbers, try to use some other identifier to help your reader find your original source. Heading titles, section titles, and paragraph numbers can help you identify the section of your source which you quoted.

If your source has no section or heading titles, count the paragraphs from the top to where your quote is, and use that as a paragraph number for your in-text citation. If the source is quite long, it will (hopefully) have headings, which you can use to point to a section, and then count the paragraphs down from that section to the location of your quotation.

For example:

According to Smith (1980), "The engineers’ most productive month of the year was April." (Seasonal Affective Disorder section, para. 4).

For more information, see the following source:

Purdue OWL - Sources Without Page Numbers

Formatting & Basic Rules

Q: What if we are writing the paper as a group (multiple authors)? How do we format the title page in this case?

A: Put all of the authors’ names on one line, in order by contribution, separated by commas, with the last author preceded by the word “and.” Or just use the word "and" in between if there are only two names.

Source and example at: APA Student Title Page Guide

Q: What if I include an image in my paper? How should I present the image and cite the source?

A: Any image you include should have a figure number and title below the image. If you did not take the photo yourself, you must include a citation for the image in a caption beneath the image.

For information on how to cite an image, see: https://libguides.scf.edu/c.php?g=847004&p=6077102

For more information on using Figures, Tables, and Graphs – see the following sources:

Purdue OWL APA Tables & Figures

Publication Manual of the American Psychological Association (7th ed.) pp.195 - 250

Q: What is common knowledge information and why don’t I need to cite it?

A: Common knowledge means that the information is generally known by professionals in the field of research you are conducting. You don’t need to cite it because you could find this same piece of information in a number of sources, therefore it is not a unique idea to any one source. This is a "gray area" of citation that falls upon the discretion of the writer. The Purdue OWL APA Guide recommends finding the information in at least five different sources before deciding it is common knowledge. When in doubt, cite the source.

For more information on Common Knowledge practices, see the following sources:

Purdue OWL - Common Knowledge & Attribution

What is Common Knowledge?

Paraphrasing & Quoting

Q: What is the difference between paraphrasing and quoting?

A: Quoting is when you take a portion of your source and copy it exactly word-for-word into your paper. In this case, you are taking the author’s language and tone along with his/her ideas. Quoting is best for cases when the author's phrasing is the best way to convey the idea to your reader.

Paraphrasing is when you describe someone else’s ideas using your own unique language and tone. Paraphrasing is the best way to keep the paper’s tone your own. Even though you are using your own language to convey the idea, the idea is still the author’s and must be cited.

For more info, see: Purdue Guide to Quoting, Paraphrasing, and Summarizing

Q: How should I format quotations?

A: If the quotation is less than 40 words long , you can simply put quotation marks around the quote. Often times, writers will use a signal phrase to identify the author and year to begin the quote, then put the page number of the source at the end of the sentence. If you do not identify the author and year in the signal phrase, then you will need to include them at the end-of-sentence citation as you would normally do.

According to Smith (1980), "The engineers’ most productive month of the year was April." (p. 86).

If the quotation is more than 40 words long , you will need to create a block-quotation. To do this, start the quotation on a new line and left-indent it by half an inch. In this case, you will not need quotation marks. The quote will still be double-spaced and have an in-text citation at the end.

Smith’s (1980) study found that:

Seasonal affective disorder decreased the productivity of 86% of the engineers at the lab. My hypothesis is that the decreased levels of sunlight and increased indoor living caused a lack of motivation on the part of the engineers and therefore their productivity decreased. Furthermore, the engineers’ most productive month of the year was April, probably due to the fact that April is the first significantly warm month after several months of a cold and dreary winter. (p. 86)

Keep in mind that whenever you use a quotation in your paper, you must cite the page or range of pages it comes from.

For more information on using quotations, see: https://writingcenter.unc.edu/handouts/quotations/

Q: My professor says I am paraphrasing / quoting too much in my paper? I am citing everything; what’s the problem?

A: If you are citing everything that comes from another source, that’s great! That means you are avoiding plagiarism. However, you want the majority of your paper to be your ideas. You don’t want to just compile other peoples’ ideas. You want to analyze and make conclusions about those other peoples’ ideas. In this way, your writing adds to the conversation on a topic so that whoever reads your paper will have a better understanding of that topic, and they will be able to add their own voice to the conversation in turn. Make sure no more than 50% of your paper is ideas from other sources.

Q: If I’m paraphrasing a theory or idea somewhere in my paper that takes up an entire paragraph of text, do I have to put an in-text citation for the same source after every single sentence?

A: According to the APA Style Webpage, "A paraphrase may continue for several sentences. In such cases, cite the work being paraphrased on first mention. Once the work has been cited, it is not necessary to repeat the citation as long as the context of the writing makes it clear that the same work continues to be paraphrased."

Tricky Questions

Q: How do I cite a source within a source?

A: A "source within a source" is often referred to as a secondary source. Here are some examples:

• A book quoted in another book.
• An article paraphrased and cited in another article.
• A book paraphrased and cited in an article.
• ...And so on. Anytime a source is cited in another source, that means the source you are using counts as a secondary source for that specific piece of information.

Here is what the APA Publication Manual 7th Edition (p. 258) says about using secondary sources:

In scholarly work, a primary source reports original content; a secondary source refers to content first reported in another source. Cite secondary sources sparingly—for instance, when the original work is out of print, unavailable, or available only in a language that you do not understand. If possible, as a matter of good scholarly practice, find the primary source, read it, and cite it directly rather than citing a secondary source. For example, rather than citing an instructor’s lecture or a textbook or encyclopedia that in turn cites original research, find, read, and cite the original research directly (unless an instructor has directed you to do otherwise).

When citing a secondary source, provide a reference list entry for the secondary source that you used. In the text, identify the primary source and then write “as cited in” the secondary source that you used. If the year of publication of the primary source is known, also include it in the text.

For example, if you read a work by Lyon et al. (2014) in which Rabbitt (1982) was cited, and you were unable to read Rabbitt’s work yourself, cite Rabbitt’s work as the original source, followed by Lyon et al.’s work as the secondary source. Only Lyon et al.’s work appears in the reference list.

(Rabbitt, 1982, as cited in Lyon et al., 2014)

If the year of the primary source is unknown, omit it from the in-text citation.

Allport’s diary (as cited in Nicholson, 2003)

• Walden University "Citing a Source within a Source"

Q: How do I cite a famous quote?

A: The APA Style Blog discusses how you would cite a famous speech in a paper, so you would use the same rule for citing a quote by a famous person. In both cases, you don’t reference the speech or quote directly- instead, you find an authoritative (reliable) source where that quote or speech is located and cite that. So for example, if you found one of Dr. Martin Luther King’s speeches in a book about great 20th century speeches, you would cite that book in your reference list. The key is to find that quote in a reliable source—don’t just use some random website without some idea of who created it. (Please note that this entry from the APA Style Blog was written for APA 6th edition, so please don't use the reference citation examples given in the link above. However, the concepts described above are still the same.)

If you need to find a source on the web with the quote, we recommend using the Advanced Google Search to find it. Go into Advanced Google and type in keywords from the quote you want to cite in your paper. Then, under “Search within a site or domain,” specify either “.gov,” “.edu” or “.org.” (Stay away from “.com’s.”) This way, you can cite a reliable website published by an organization or an educational or governing entity. For example, you could go to www.winstonchurchill.org to try and find a quote by Winston Churchill, instead of a .com site. Your citation would then be the same as citing a specific page on a website (see the Purdue OWL Example for "Webpage or Piece of Online Content" for the proper citation example).

Q: How do I cite the results of an online personality test I took?

A: This one is definitely tricky. If you need to cite the results of an online test you took, do it the same as you would any other website if you took the test online. Cite it as a book if you got the test from a book, and so on. List the author as whoever issued the test -- was it an organization? Institute? Then, try to find the latest copyright date—or preferably a date that will tell you the last time the test was updated if it is online. The title is going to be whatever is listed at the top of the test or test results. Finally, put a retrieval web address for the test site, and include the date that you retrieved the test results. Here is an example for you to follow:

Enneagram Institute. (2011). Title of test. Retrieved December 3, 2011 from http://www.enneagraminstitute.com/discover.asp/

Q: How do I cite the Diagnostic and Statistical Manual of Mental Disorders (DSM)?

Being responsible while researching

When you’re writing a research paper or creating a research project, you will probably use another individual’s work to help develop your own assignment. A good researcher or scholar uses another individual’s work in a responsible way. This involves indicating that the work of other individuals is included in your project (i.e., citing), which is one way to prevent plagiarism.

Plagiarism? What is it?

The word plagiarism is derived from the Latin word, plagiare , which means “to kidnap.” The term has evolved over the years to now mean the act of taking another individual’s work and using it as your own, without acknowledging the original author (American Psychological Association, 2020 p. 21). Plagiarism can be illegal and there can be serious ramifications for plagiarizing someone else’s work. Thankfully, plagiarism can be prevented. One way it can be prevented is by including citations and references in your research project. Want to make them quickly and easily? Try the Citation Machine citation generator, which is found on our homepage.

All about citations & references

Citations and references should be included anytime you use another individual’s work in your own assignment. When including a quote, paraphrased information, images, or any other piece of information from another’s work, you need to show where you found it by including a citation and a reference. This guide explains how to make them.

APA style citations are added in the body of a research paper or project and references are added to the last page.

Citations , which are called in-text citations, are included when you’re adding information from another individual’s work into your own project. When you add text word-for-word from another source into your project, or take information from another source and place it in your own words and writing style (known as paraphrasing), you create an in-text citation. These citations are short in length and are placed in the main part of your project, directly after the borrowed information.

References are found at the end of your research project, usually on the last page. Included on this reference list page is the full information for any in-text citations found in the body of the project. These references are listed in alphabetical order by the author's last name.

An APA in-text citation includes only three items: the last name(s) of the author(s), the year the source was published, and sometimes the page or location of the information. References include more information such as the name of the author(s), the year the source was published, the full title of the source, and the URL or page range.

Why is it important to include citations & references

Including APA citations and references in your research projects is a very important component of the research process. When you include citations, you’re being a responsible researcher. You’re showing readers that you were able to find valuable, high-quality information from other sources, place them into your project where appropriate, all while acknowledging the original authors and their work.

Common ways students and scholars accidentally plagiarize

Believe it or not, there are instances when you could attempt to include in-text and full references in the appropriate places, but still accidentally plagiarize. Here are some common mistakes to be aware of:

Mistake #1 - Misquoting sources: If you plan to use a direct quote, make sure you copy it exactly as is. Sure, you can use part of the full quote or sentence, but if you decide to put quotation marks around any words, those words should match exactly what was found in the original source. Here’s a line from The Little Prince , by Antoine de Saint-Exupéry:

“Grown-ups never understand anything by themselves, and it is tiresome for children to be always and forever explaining things to them.”

Here’s an acceptable option:

“Grown-ups never understand anything by themselves,” stated de Saint-Exupéry (1943, p. 3).

Here’s a misquote:

“Grown-ups barely ever understand anything by themselves,” stated de Saint-Exupéry (1943, p. 3).

Notice the slight change in the words. The incorrect phrasing is an instance of accidental plagiarism.

Mistake #2 - Problems with paraphrasing: When we paraphrase, we restate information using our own words and writing style. It’s not acceptable to substitute words from the original source with synonyms.

Let’s use the same sentence from The Little Prince .

A correct paraphrase could be:

de Saint-Exupéry (1943) shares various ways adults frustrate children. One of the biggest being that kids have to explain everything. It’s too bad adults are unable to comprehend anything on their own (p. 3).

An incorrect paraphrase would be:

de Saint-Exupéry (1943) shares that adults never understand anything by themselves, and it is exhausting for kids to be always and forever clarifying things to them (p.3).

Notice how close the incorrect paraphrase is from the original. This is an instance of accidental plagiarism.

Make sure you quote and paraphrase properly in order to prevent accidental plagiarism.

If you’re having a difficult time paraphrasing properly, it is acceptable to paraphrase part of the text AND use a direct quote. Here’s an example:

de Saint-Exupery (1943) shares various ways adults frustrate children. One of the biggest being that kids have to explain everything, and “it is tiresome for children to be always and forever explaining things to them” (p. 3).

Information About APA

Who created it.

The American Psychological Association is an organization created for individuals in the psychology field. With close to 121,000 members, they provide educational opportunities, funding, guidance, and research information for everything psychology-related. They also have numerous high-quality databases, peer-reviewed journals, and books that revolve around mental health.

The American Psychological Association is also credited with creating their own specific citation and reference style. Today, this format is used by individuals not only in the psychology field, but many other subject areas as well. Education, economics, business, and social sciences also use APA style quite frequently. Click here for more information . This guide covers general information about the style, but is not affiliated with the American Psychological Association.

Why was this style created?

This format was first developed in 1929 to form a standardized way for researchers in science fields to document their sources. Prior to the inception of these standards and guidelines, individuals were recognizing the work of other authors by including bits and pieces of information in random order. There wasn’t a set way to format citations and references. You can probably imagine how difficult it was to understand the sources that were used for research projects!

Having a standard format for citing sources allows readers to glance at a citation or APA reference and easily locate the title, author, year published, and other critical pieces of information needed to understand a source.

The evolution of this style

The guide below is based on APA style 7th edition, which was released in 2020. In previous versions of APA format, researchers and scholars were required to include the publisher location for books and the date that an electronic resource was accessed. Both are no longer required to be included.

Details on the differences between the 6th and 7th editions is addressed later in this guide.

Citations & References

The appearance of citations & references.

The format for references varies, but most use this general format:

%%Author’s Last name, First initial. (Date published). Title . URL

Researchers and scholars must look up the proper format for the source that they’re attempting to cite. Books have a certain format, websites have a different format, periodicals have a different format, and so on. Scroll down to find the proper format for the source you’re citing or referencing.

• Journal articles

In-text citations

An APA in-text citation is included in research projects in three instances: When using a direct quote, paraphrasing information, or simply referring to a piece of information from another source.

Quite often, researchers and scholars use a small amount of text, word for word, from another source and include it in their own research projects. This is done for many reasons. Sometimes, another author’s words are so eloquently written that there isn’t a better way to rephrase it yourself. Other times, the author’s words can help prove a point or establish an understanding for something in your research project. When using another author’s exact words in your research project, include an APA in-text citation directly following it.

In addition to using the exact words from another source and placing them into your project, these citations are also added anytime you paraphrase information. Paraphrasing is when you take information from another source and rephrase it, in your own words.

When simply referring to another piece of information from another source, also include a citation directly following it.

Citations in the text are found near a direct quote, paraphrased information, or next to a mention of another source. To see examples of some narrative/ parenthetical citations in action, look at the image above, under “All About Citations & References.”

Note: *Only include the page or paragraph number when using a direct quote or paraphrase. Page numbers have a p. before the number, pp. before the page range, and para. before the paragraph number. This information is included to help the reader locate the exact portion of text themselves. It is unnecessary to include this information when you’re simply referring to another source.

Examples of APA in-text citations:

“Well, you’re about to enter the land of the free and the brave. And I don’t know how you got that stamp on your passport. The priest must know someone” (Tóibín, 2009, p. 52).

Student teachers who use technology in their lessons tend to continue using technology tools throughout their teaching careers (Kent & Giles, 2017, p. 12).

If including the author’s name in the sentence, place the year in the parentheses directly next to his or her name. Add the page number at the end, unless it’s a source without any pages or paragraph numbers (See Section 8.10 of the Publication manual for more details).

In-text citation APA example:

According to a study done by Kent and Giles (2017), student teachers who use technology in their lessons tend to continue using technology tools throughout their teaching careers.

The full references, or citations, for these sources can be found on the last part of a research project, titled the “References.”

Here’s how to create in-text citations for specific amounts of authors:

APA citation with no author

When the source lacks an author’s name, place the title, year, and page number (if available) in the text. The title should be in italics if it sits alone (such as a movie, brochure, or report). If the source is part of a whole (as many web pages and articles are), place the title in quotation marks without italics (See Section 8.14 of the Publication manual ).

Structure of an APA format citation in the text narratively, with the author's name missing:

Title of Source (Year) or “Title of Source” (Year)

Structure of an APA style format citation, in parentheses at the end of the sentence, with the author’s name missing: (Title of Source, Year) or (“Title of Source,” Year)

Structure for one author

In the text, narratively: Last name of Author (Year)...(page number).

In parentheses, at the end of the sentence: (Last name of Author, Year, page number).

Structure for two authors

Place the authors in the order they appear on the source. Only use the ampersand in the parenthetical citations (see Section 8.17 of the Publication manual ). Use ‘and’ to separate the author names if they’re in the text of the sentence.

In the text, narratively: Last name of Author 1 and Last name of Author 2 (Year)....(page number).

In parentheses, at the end of the sentence: (Last name of Author 1 & Last name of Author 2, Year, page number).

Structure for three or more authors

Only include the first listed author’s name in the first and any subsequent citations. Follow it with et al.

(Last name Author 1 et al., Year, page number)

(Agbayani et al., 2020, p. 99)

Last name of Author 1 et al. (Year)...(page).

Agbayani et al. (2020)...(p. 99)

One author, multiple works, same year

What do you do when you want to cite multiple works by an author, and the sources all written in the same year?

Include the letters ‘a’ ‘b’ ‘c’ and so on after the year in the citation.

(Jackson, 2013a)

Jackson (2013a)

Writers can even lump dates together.

Example: Jackson often studied mammals while in Africa (2013a, 2013b).

On the APA reference page, include the same letters in the full references.

Groups and organizations

Write out the full name of the group or organization in the first citation and place the abbreviation next to it in brackets. If the group or organization is cited again, only include the abbreviation. If it doesn’t have an abbreviation associated with it, write out the entire organization’s name each and every time (see Section 8.21 of the Publication manual ).

First APA citation for an organization with an abbreviation: (World Health Organization [WHO], Year)

World Health Organization (WHO, Year)

Notice in the example directly above, the name of the organization is written out in full in the text of the sentence, and the abbreviation is placed in parentheses next to it.

Subsequent APA citations in the text for an organization with an abbreviation: (WHO, Year) OR WHO (Year)

All citations in the text for an organization without an abbreviation: (Citation Machine, Year) or Citation Machine (Year)

One in-text citation, multiple works

Sometimes you’ll need to cite more than one work within an in-text citation. Follow the same format (author, year) format but place semicolons between works (p. 263).

(Obama, 2016; Monroe et al., 1820; Hoover & Coolidge, 1928)

Reference list citation components

References display the full information for all the citations found in the body of a research project.

Some things to keep in mind when it comes to the references:

• All references sit together on their own page, which is usually the last page(s) of a paper.
• Title the page ‘References’
• Place ‘References’ in the center of the page and bold it. Keep the title in the same font and size as the references. Do not italicize, underline, place the title in quotation marks, or increase the font size.
• The entire page is double spaced.
• All references are listed in alphabetical order by the first word in the reference, which is usually the author’s last name. If the source lacks an author, alphabetize the source by the title (ignore A, An, or The)
• All references have a hanging indent, meaning that the second line of text is indented in half an inch. See examples throughout this guide.
• Remember, each and every citation in the text of the paper MUST have a full reference displayed in the reference list. The citations in the text provide the reader with a quick glimpse about the sources used, but the references in the reference list provide the reader with all the information needed to seek out the source themselves.

Learn more about each component of the reference citation and how to format it in the sections that follow. See an APA sample paper reference list at the end of this entire section.

Author’s names

The names of authors are written in reverse order. Include the initials for the first and middle names. End this information with a period (see Section 9.8 of the Publication manual ).

Format: Last name, F. M.

• Angelou, M.
• Doyle, A. C.

Two or more authors

When two or more authors work together on a source, write them in the order in which they appear on the source. You can name up to 20 authors in the reference. For sources with 2 to 20 authors, place an ampersand (&) before the final author. Use this format:

Last name, F. M., & Last name, F. M.

Last name, F. M., Last name, F. M., Last name, F. M., Last name, F. M., & Last name, F. M.

Kent, A. G., Giles, R. M., Thorpe, A., Lukes, R., Bever, D. J., & He, Y.

If there are 21 or more authors listed on a source, only include the first 19 authors, add three ellipses, and then add the last author’s name.

Roberts, A., Johnson, M. C., Klein, J., Cheng, E. V., Sherman, A., Levin, K. K. , ...Lopez, G. S.

If you plan on using a free APA citation tool, like the one at CitationMachine.com, the names of the authors will format properly for you.

###No authors

If the source lacks an author, place the title in the first position in the reference (Section 9.12 of the Publication manual ). When the source’s title begins with a number (Such as 101 Dalmatians ), place the reference alphabetically as if the number was spelled out. 101 Dalmatians would be placed in the spot where ‘One hundred’ would go, but keep the numbers in their place.

Additionally, if the title begins with the words ‘A’, ‘An,’ or ‘The,’ ignore these words and place the title alphabetically according to the next word.

See the “Titles” section below for more information on formatting the title of sources.

###Corporate/Organization authors

On an APA reference page, corporate authors are always written out in full. In the text of your paper, you may have some abbreviations (such as UN for United Nations), but in the full references, always include the full names of the corporation or organization (following Section 9.11 of the official Publication manual ).

%%United Nations. (2019). Libya: $202 million needed to bring life-saving aid to half a million people hit by humanitarian crisis. https://news.un.org/en/story/2019/02/1031981

Directly after the author’s name is the date the source was published. Include the full date for newspapers and magazine articles, and only the year for journals and all other sources. If no date is found on the source, include the initials, n.d. for “no date.”

%% Narducci, M. (2017, May 19). City renames part of 11th Street Ed Snider Way to honor Flyers founder. The Philadelphia Inquirer . http://www.philly.com/

If using our APA Citation Machine, our citation generator will add the correct format for you automatically.

Giving a retrieval date is not needed unless the online content is likely to be frequently updated and changed (e.g., encyclopedia article, dictionary entry, Twitter profile, etc.).

%%Citation Machine [@CiteMachine]. (n.d.). Tweets [Twitter profile]. Twitter. Retrieved October 10, 2019, from https://twitter.com/CiteMachine

When writing out titles for books, articles, chapters, or other non-periodical sources, only capitalize the first word of the title and the first word of the subtitle. Names of people, places, organizations, and other proper nouns also have the first letter capitalized. For books and reports, italicize the title in the APA citation.

Strange case of Dr. Jekyll and Mr. Hyde.

Roots: The saga of an American family.

For articles and chapters in APA referencing, do not italicize the title.

Wake up the nation: Public libraries, policy making, and political discourse.

For newspapers, magazines, journals, newsletters, and other periodicals, capitalize the first letter in each word and italicize the title.

The Seattle Times.

A common question is whether to underline your title or place it in italics or quotation marks in the reference list. Here’s a good general rule: When a source sits alone and is not part of a larger whole, place the title in italics. If the source does not sit alone and is part of a larger whole, do not place it in italics.

Books, movies, journals, and television shows are placed in italics since they stand alone. Songs on an album, episodes of television shows, chapters in books, and articles in journals are not placed in italics since they are smaller pieces of larger wholes.

The Citation Machine citation generator will format the title in your citations automatically.

Additional information about the title

If you feel it would be helpful to include additional information about the source type, include a descriptive noun or two in brackets immediately following the title. Capitalize the first letter.

%%Kennedy, K., & Molen, G. R. (Producers), & Spielberg, S. (Director). (1993). Jurassic Park [Film]. USA: Universal.

Besides [Film], other common notations include:

• [Audio podcast]
• [Letter to the editor]
• [Television series episode]
• [Facebook page]
• [Blog post]
• [Lecture notes]
• [PowerPoint presentation]
• [Video file]

If you are using Citation Machine citing tools, additional information about the title is automatically added for you.

Publisher information

For books and reports, include the publisher name but not the location (see Section 9.29 of the Publication manual ). Older editions of the style required the city, state and/or country, but this hasn't been the case since the 7th edition was released.

It is not necessary to include the entire name of the publisher. It is acceptable to use a brief, intelligible form. However, if Books or Press are part of the publisher’s names, keep these words in the reference. Other common terms, such as Inc., Co., Publishers, and others can be omitted.

For newspapers, journals, magazines, and other periodicals, include the volume and issue number after the title. The volume number is listed first, by itself, in italics. The issue number is in parentheses immediately after it, not italicized. There is no space after the closing parenthesis and before the volume number.

%%Giannoukos, G., Besas, G., Hictour, V., & Georgas, T. (2016). A study on the role of computers in adult education. Educational Research and Reviews , 11 (9), 907-923. https://doi.org/10.5897/ERR2016.2688

After including the publisher information, end this section with a period.

Perseus Books.

Electronic source information:

For online sources, the URL or DOI (Direct Object Identifier) are included at the end of an APA citation.

DOI numbers are often created by publishers for journal articles and other periodical sources. They were created in response to the problem of broken or outdated links and URLs. When a journal article is assigned a DOI number, it is static and will never change. Because of its permanent characteristic, DOIs are the preferred type of electronic information to include in APA citations. When a DOI number is not available, include the source’s URL (see Section 9.34 in the Publication manual ).

For DOIs, include the number in this format:

http://doi.org/xxxx

For URLs, type them in this format:

http:// or https://

Other information about electronic sources:

• If the URL is longer than a line, break it up before a punctuation mark.
• Do not place a period at the end of the citation/URL.
• It is unnecessary to include retrieval dates, unless the source changes often over time (like in a Wikipedia article).
• It is not necessary to include the names of databases

If using the Citation Machine APA citation website autocite features, the online publication information will be automatically replaced by the DOI. The Citation Machine APA template will properly cite your online sources for you.

Make sure you run your completed paper through the Citation Machine Plus smart proofreader, which scans for grammar, spelling, and plagiarism. Whether it’s an adjective , verb , or pronoun out-of-place, our technology helps edits your paper for you!

Annotated bibliographies:

An APA annotated bibliography is a full bibliography that includes a small note for each reference citation. Each note should be short (1-2 paragraphs) and contain a summary or your evaluation about each source. When creating your citations on CitationMachine.net, there is a field at the bottom of each form to add your own annotations.

Follow the publication manual guidelines on paper format and writing style. Let your instructor guide other details about your annotations. Still confused? Read our guide on annotated bibliographies .

These types of projects look different depending on the style you’re using. Use the link at the top of the page to access resources related to the Modern Language Association’s style. Here’s information related to Chicago citation style .

Page formatting

Need help with the design and formatting of your paper? Look no further! This section provides the ins and outs of properly displaying the information in your APA essay.

• Times New Roman, 12-point size.
• Calibri, Arial, or Georgia, 11-point size
• Lucida, Sans Unicode, or Computer Modern, 10-point size
• Indents = Every paragraph should start with an indent.
• Margins = 1 inch around the entire document
• Spacing = Double space everything!

Arrange your pages in this order:

• Page 1 - APA Title Page (see below for information on the title page)
• Page 2 - Abstract (If your professor requests one)
• Page 3 - First page of text
• References begin on their own page. Include the list of references on the page after the text.
• Tables and figures

Keep in mind that the order above is the recommendation for papers being submitted for peer review. If you’re writing an APA style paper for a class, your professor may be more lenient about the requirements. Also, if you’re submitting your paper for a specific journal, check the requirements on the journal’s website. Each journal has different rules and procedures.

Just a little nudge to remind you about the Citation Machine Plus smart proofreader. Whether it’s a conjunction or interjection out of place, a misspelled word, or an out of place citation, we’ll offer suggestions for improvement! Don’t forget to check out our APA citation maker while you’re at it!

Running heads

In older editions of APA, running heads were required for all papers. Since the 7th edition, that’s changed.

• Student paper: No running head
• Professional paper: Include a running head

The running head displays the title of the paper and the page number on all pages of the paper. This header is found on every page of a professional paper (not a student paper), even on the title page (sometimes called an APA cover page) and reference list (taken from Section 2.8 of the Publication manual ).

It's displayed all in capital letters at the top of the page. Across from the running head, along the right margin, is the page number.

• Use the header feature in your word processor. Both Google Docs and Word have these features available.
• Use one for the recommended fonts mentioned under "Page formatting."

Title pages

A title page, sometimes called an APA cover page, graces the cover of an essay or paper. An APA title page should follow rules from Section 2.3 of the official Publication manual and include:

• Page number, which is page 1
• Use title case and bold font
• The title should be under 12 words in length
• The title should be a direct explanation of the focus of the paper. Do not include any unnecessary descriptors such as “An Analysis of…” or “A Study of…”
• Exclude any labels such as Mr., Ms., Dr, PhD...
• Name of the school or institution
• Course number and/or class name
• Name of your instructor, including their preferred honorifics (e.g., PhD, Dr., etc.)
• Paper’s due date
• If this is a professional paper, also include a running head. If this is a student paper, do not include one.

Follow the directions for the running head and page number in the section above. Below the running head, a few lines beneath, and centered in the middle of the page, should be the title. The next line below is the author’s name(s), followed by the name of the school or institution, the class or course name, your instructor’s name, and the paper’s due date.

All components on this page should be written in the same font and size as the rest of your paper. Double space the title, names, name of school or institution, and all other information on the page (except for the running head and page number).

Example - Student Title Page APA:

Example - Professional Title Page APA:

If you’re submitting your paper to a journal for publication, check the journal’s website for exact requirements. Each journal is different and some may request a different type of APA format cover page.

Looking to create an APA format title page? Head to CitationMachine.com’s homepage and choose “Title Page” at the top of the screen.

An abstract briefly but thoroughly summarizes dissertation contents. It’s found in the beginning of a professional paper, right after the title page. Abstracts are meant to help readers determine whether to continue reading the entire document. With that in mind, try to craft the lead sentence to entice the reader to continue reading.

Here are a few tips:

• Be factual and keep your opinions out. An abstract should accurately reflect the paper or dissertation and should not involve information or commentary not in the thesis.
• Communicate your main thesis. What was the examined problem or hypothesis? A reader should know this from reading your abstract.
• Keep it brief. Stick to the main points and don’t add unnecessary words or facts. It should not exceed 250 words.
• Consider your paper’s purpose. It’s important to cater your abstract to your paper type and think about what information the target audience for that paper type would want. For example, an empirical article may mention methodology or participant description. A quantitative or qualitative meta-analysis would mention the different variables considered and how information was synthesized.
• Use verbs over noun equivalents, and active voice. Example: “There was research into…” becomes “We researched…”

Formatting guidelines:

• The abstract goes after the title page.
• It should have the same font (size and type) as the rest of the paper.
• It should stick to one page.
• Double-space all page text.
• Center and bold the word “Abstract” at the top of the paper.
• Don’t indent the first line of the abstract body. The body should also be in plain text.
• For the keywords, place it on the line after the abstract and indent the first line (but not subsequent lines). The word “Keywords:” is capitalized, italicized, and followed by a colon. The actual keywords are sentence case and in plan font.
• List each keyword one after the other, and separate them by a comma.
• After the last keyword, no ending punctuation is needed.

Tables & Figures

If your paper includes a lot of numerical information or data, you may want to consider placing it into a table or a figure, rather than typing it all out. A visual figure or simple, organized table filled with numerical data is often easier for readers to digest and comprehend than tons of paragraphs filled with numbers. Chapter 7 of the Publication manual outlines formatting for tables and figures. Let's cover the basics below.

If you’d like to include a table or figure in your paper, here are a few key pieces of information to keep in mind:

• At the end of the paper after the APA reference page
• In the text after it is first mentioned
• The table first mentioned in the text should be titled ‘Table 1.’ The next table mentioned in the text is ‘Table 2,’ and so on. For figures, it would be 'Figure 1,' 'Figure 2,' and so forth.

• Even though every table and figure is numbered, also create a title for each that describes the information it contains. Capitalize all important words in the title.
• For tables, do not use any vertical lines, only use horizontal to break up information and headings.
• Single spacing is acceptable to use in tables and figures. If you prefer double spacing your information, that is okay too.
• Do not include extra information or “fluff.” Keep it simple!
• Do not include the same exact information in the paper. Only include the complete information in one area—the table or the text.
• All tables and figures must be referenced in the text. It is unacceptable to throw a table or figure into the back of the paper without first providing a brief summary or explanation of its relevance.

Publication Manual 6th Edition vs 7th Edition

The 6th edition of the Publication Manual of the American Psychological Association was released in 2009. The current 7th edition came out in the fall of 2019 and was designed to be more student focused, provide more guidance on accessibility, and address changes that have developed over the last 10 years.

Below, we’ve listed what we feel are the most relevant changes related to APA format.

Journals and DOIs

DOI stands for “digital object identifier.” Many journal articles use and have a unique DOI that should be included in a full citation.

When including a DOI in a citation, format it as a URL. Do not label it “DOI.” Articles without DOIs from databases are treated as print works. For example:

6th edition:

%%Gänsicke, B. T., Schreiber, M. R., Toloza, O., Fusillo, N. P. G., Koester, D., & Manser, C. J. (2019). Accretion of a giant planet onto a white dwarf star. Nature, 576 (7785), 61–64. doi: 10.1038/s41586-019-1789-8

7th edition:

%%Gänsicke, B. T., Schreiber, M. R., Toloza, O., Fusillo, N. P. G., Koester, D., & Manser, C. J. (2019). Accretion of a giant planet onto a white dwarf star. Nature, 576 (7785), 61–64. https://doi.org/10.1038/s41586-019-1789-8

Citing Books

There are few new guidelines when you are citing a book. First, the publisher location no longer needs to be indicated.

%%Zack, P. O. (2001). The shoals of time. Bloomington, IN: First Books Library.

%%Zack, P. O. (2001). The shoals of time. First Books Library.

Second, the format of an ebook (e.g., Kindle, etc.) no longer needs to be indicated.

%%Niven, J. (2012). Ada Blackjack: A true story of survival in the Arctic [Kindle].

%%Niven, J. (2012). Ada Blackjack: A true story of survival in the Arctic .

Lastly, books from research databases without DOIs are treated the same as print works.

When using a URL in a citation, you no longer need to include the term “Retrieved from” before URLs (except with retrieval dates). The font should be blue and underlined, or black and not underlined.

6th Edition:

%%Flood, A. (2019, December 6). Britain has closed almost 800 libraries since 2010, figures show. The Guardian . Retrieved from https://www.theguardian.com/books/2019/dec/06/britain-has-closed-almost-800-libraries-since-2010-figures-show

7th Edition:

%%Flood, A. (2019, December 6). Britain has closed almost 800 libraries since 2010, figures show. The Guardian . https://www.theguardian.com/books/2019/dec/06/britain-has-closed-almost-800-libraries-since-2010-figures-show

Within a full APA citation, you may spell out up to 20 author names. For two to 20 authors, include an ampersand (&) before the name of the last author. For sources with 21 or more authors, structure it as follows:

Structure: First 19 authors’ names, . . . Last author’s name.

7th edition example: Washington, G., Adams, J., Jefferson, T., Madison, J., Monroe, J., Adams, J. Q., Jackson, A., Van Buren, M., Harrison, W. H., Tyler, J., Polk, J. K., Taylor, Z., Filmore, M., Pierce, F., Buchanan, J., Lincoln, A., Johnson, A., Grant, U. S., Hayes, R. B., Garfield, . . . Trump, D.

When creating an in-text citation for a source with 3 or more authors, use “et al.” after the first author’s name. This helps abbreviate the mention.

6th Edition: (Honda, Johnson, Prosser, Rossi, 2019)

7th Edition: (Honda et al., 2019)

Tables and Figures

Instead of having different formats for tables and figures, both use one standardized format. Now both tables and figures have a number, a title, name of the table/figure, and a note at the bottom.

🤔 What is an APA Citation Generator?

An APA citation generator is a software tool that will automatically format academic citations in the American Psychological Association (APA) style.

It will usually request vital details about a source -- like the authors, title, and publish date -- and will output these details with the correct punctuation and layout required by the official APA style guide.

Formatted citations created by a generator can be copied into the bibliography of an academic paper as a way to give credit to the sources referenced in the main body of the paper.

👩‍🎓 Who uses an APA Citation Generator?

College-level and post-graduate students are most likely to use an APA citation generator, because APA style is the most favored style at these learning levels. Before college, in middle and high school, MLA style is more likely to be used. In other parts of the world styles such as Harvard (UK and Australia) and DIN 1505 (Europe) are used more often.

🙌 Why should I use a Citation Generator?

Like almost every other citation style, APA style can be cryptic and hard to understand when formatting citations. Citations can take an unreasonable amount of time to format manually, and it is easy to accidentally include errors. By using a citation generator to do this work you will:

• Save a considerable amount of time
• Ensure that your citations are consistent and formatted correctly
• Be rewarded with a higher grade

In academia, bibliographies are graded on their accuracy against the official APA rulebook, so it is important for students to ensure their citations are formatted correctly. Special attention should also be given to ensure the entire document (including main body) is structured according to the APA guidelines. Our complete APA format guide has everything you need know to make sure you get it right (including examples and diagrams).

⚙️ How do I use MyBib's APA Citation Generator?

Our APA generator was built with a focus on simplicity and speed. To generate a formatted reference list or bibliography just follow these steps:

• Start by searching for the source you want to cite in the search box at the top of the page.
• MyBib will automatically locate all the required information. If any is missing you can add it yourself.
• Your citation will be generated correctly with the information provided and added to your bibliography.
• Repeat for each citation, then download the formatted list and append it to the end of your paper.

MyBib supports the following for APA style:

Origination of APA Style

• Where did APA Style come from?

Commonly Used APA Related Terms

Abstract : Abstract is a brief synopses of article. It provides a brief but comprehensive summary of the article. 

Citing : In the context of academic writing, citing is the act of acknowledging the sources of information you have used when writing your work.

Citation:  A citation gives credit to a source, and contains publication information such as author(s), title and date.

DOI (digital object identifier): It is a unique alphanumeric string assigned to a digital object, mainly a scholarly article, to provide a persistent link to its location on the internet. 

In-Text Citation : It is a brief note that appears within the body of the paper and briefly identifies the cited work by its author and date of publication. An in-text citation should always match the corresponding entry in the reference list at the end of paper.

Paraphrasing : A paraphrase restates another’s idea (or your own previously published idea) in your own words. 

Plagiarism : It is the act of presenting the words, ideas, or images of another as your own; it denies creators of content the credit they are due. 

Quoting : It is the act of reproducing the exact wording used by the original author. Direct quotations appear within quotation marks and end with a citation.

Reference : It contains details about one cited work, generally including four elements:  author, date, title, and source.  

Reference List : It identifies all the sources you cited in the text of your paper. It generally is at the end of the paper and definitely on a new page after the text of your paper. 

APA Style is the most common writing style used in college and career. Its purpose is to promote excellence in communication by helping writers create clear, precise, and inclusive sentences with a straightforward scholarly tone. It addresses areas of writing such as how to

• format a paper so it looks professional;
• credit other people’s words and ideas via citations and references to avoid plagiarism; and
• describe other people with dignity and respect using inclusive, bias-free language.

APA Style is primarily used in the behavioral sciences, which are subjects related to people, such as psychology, education, and nursing. It is also used by students in business, engineering, communications, and other classes. Students use it to write academic essays and research papers in college, and professionals use it to conduct, report, and publish scientific research.

In addition, APA Style provides you with a powerful tool that will hep you avoid deliberate or unintentional plagiarism. Please review the Avoiding Plagiarism Guide created by the APA experts to understand what two common types of plagiarism are and how to avoid them. 

Why is learning citations important? Citations help readers understand where the information used in your paper comes from, enabling them to trace the path of that information. When readers wish to explore a specific point or reference cited in the text, citations make it easier by providing information about your sources in a standardized format.

Besides showing readers where you obtained information, using citations also has a strong ethical purpose. In academic writing, it is important to credit ideas that are not your own. Citations allow you to integrate the ideas of others with your own thoughts in a fair and honest way.

The reference formats for APA Style manuals are as follows:

APA Style provides a foundation for effective scholarly communication because it helps authors present their ideas in a clear and concise, and organized manner.  Uniformity and consistency enable readers to (a) focus on the ideas being presented rather than formatting and (b) scan works quickly for key points, findings, and sources. When style works best, ideas flow logically, sources are credited appropriately, and papers are organized predictably and consistently. 

Students are encouraged to first learn about APA Style by reading works written in APA Style. A couple of guides created by APA experts from the American Psychological Association can help you with that:

Anatomy of a Journal Article   https://apastyle.apa.org/instructional-aids/anatomy-journal-article.pdf

Scholarly journal articles share a common anatomy or structure. Each part of an article serves a specific purpose. The handout of  Anatomy of a Journal Article explains how journal articles are structured and how to become more efficient at reading and understanding them. Understanding the structure of a scholarly article and the purpose of each part helps you grasp a strategy called targeted reading. Targeted reading means to read specific sections of research articles first to determine if the article seems useful for your research topic. This way you will save time, find useful article faster, and choose which articles to read in full.

Reading and Understanding Abstracts https://apastyle.apa.org/instructional-aids/reading-abstracts.pdf

Abstracts are short summaries of scientific research articles. The handout of Reading & Understanding Abstracts explains the definition and purpose of abstracts and the benefits of reading them, including analysis of a sample abstract. The skill of reading and understanding abstracts of scholarly articles not only saves time but also helps you conduct better research and write more effectively.

APA Style Writing Principles https://apastyle.apa.org/instructional-aids/writing-principles.pdf

The poster created by APA experts shows the three main principles of APA Style: clarity, precision, and inclusion and lists steps on how to achieve them. As a student writer, you always should write your academic paper with clarity, precision, and inclusion. 

Research Article Activity https://apastyle.apa.org/instructional-aids/apa-style-research-activity.pdf

Reading research articles is not an easy task for you as a student. The Research Article Activity designed by APA Style experts aims to make it easy to read and understand a scholarly article. This activity worksheet helps you find, cite, analyze, and summarize a research article. Completing this activity breaks down a lengthy research article into easily understandable chunks. This way helps you better understand the study in the article before you write about it.

APA in-text citations include the author’s last name, publication date, and, if relevant, a locator such as a page number or timestamp. For example, (Smith, 2021, p. 170) . See it as a shorter version of the entry in the reference list .

You should include in-text citations every time you’re quoting or paraphrasing someone else’s ideas or words. In doing so, you give credit to the original author and avoid plagiarism .

Parenthetical vs. narrative citation

The in-text citation can take two forms: parenthetical and narrative. Both types are generated automatically when citing a source with Scribbr’s APA Citation Generator.

• Parenthetical citation: According to new research … (Smith, 2020) .
• Narrative citation: Smith (2020) notes that …

Multiple authors and corporate authors

The in-text citation changes slightly when a source has multiple authors or an organization as an author. Pay attention to punctuation and the use of the ampersand (&) symbol.

When the author, publication date or locator is unknown, take the steps outlined below.

APA references

APA references generally include information about the author , publication date , title , and source . Depending on the type of source, you may have to include extra information that helps your reader locate the source.

It is not uncommon for certain information to be unknown or missing, especially with sources found online. In these cases, the reference is slightly adjusted.

Formatting the APA reference page

On the first line of the page, write the section label “References” (in bold and centered). On the second line, start listing your references in alphabetical order .

Apply these formatting guidelines to the APA reference page:

• Double spacing (within and between references)
• Hanging indent of ½ inch
• Legible font (e.g. Times New Roman 12 or Arial 11)
• Page number in the top right header

Which sources to include

On the reference page, you only include sources that you have cited in the text (with an in-text citation ). You should not include references to personal communications that your reader can’t access (e.g. emails, phone conversations or private online material).

APA's Position on Citing AI Tools

APA's Position:  The results of a “chat” with a generative AI, like ChatGPT, are not retrievable by other readers. Although other types nonretrievable data or quotations are usually cited as personal communications in APA Style papers, with generative AI produced text there is no person communicating. Quoting an AI's text from a chat session is therefore more similar to sharing an algorithm’s output. APA, therefore recommends that citations should credit the author of the algorithm with a reference list entry and the corresponding in-text citation.

Citation Example--APA

Example from a paper showing how to use in-text citation and then the full verson of the citation used on the References page:

When prompted with “Is the left brain right brain divide real or a metaphor?” the ChatGPT-generated text indicated that although the two brain hemispheres are somewhat specialized, “the notation that people can be characterized as ‘left-brained’ or ‘right-brained’ is considered to be an oversimplification and a popular myth” (OpenAI, 2023).

Explanation of the Individual Parts of the Citation

Breaking the reference down and looking at each of the four elements (author, date, title, and source) in more detail can assist in applying this form in your own writing.:

Author:  The author of ChatGPT is OpenAI. If you are using text from a different AI tool, you will need to identify the author or creator of that tool.  See the table below to determine the Author of the most common AI Tools.

Date:  The date is the year of the version of the tool used. You only need to include the year, not the exact date. 

Title:  The name of this AI tool is “ChatGPT,” so that serves as the title and is italicized in your reference, Again, if you are using a different tool then that tool's name should for the title. The version number is included after the title in parentheses. The format for the version number in ChatGPT references includes the date because that is how OpenAI is labeling its versions. Different AI tools might use different version numbering; use the version number in the format the author or publisher provides, which may be a numbering system (e.g., Version 2.0) or other methods.

Bracketed text  is used for additional description when needed to help a reader understand what is being cited. Books and journal articles do not need bracketed descriptions but more unusual formats often do. In the case of a reference for a generative AI tool, such as ChatGPT, provide the descriptor “Large language model” in square brackets. 

Source:  When the publisher name and the author name are the same, do not repeat the publisher name in the source element of the reference, and move directly to the URL. Use the URL that links as directly as possible to the page where you can access the model

Authors of AI Tools

Using an appendix for providing the complete ai-generated text.

Because generative AI's, like Chat GPT will generate a unique response in each chat session, even if given the same prompt, APA also suggests that the full text of long responses from such sea session should be placed in an appendix of your paper if readers would greatly benefit from having access to the exact text generated. It is then particularly important to document the exact text created and the presence of such an appendix should be called out at least once in the body of your paper.

When given a follow-up prompt of “What is a more accurate representation?” the ChatGPT-generated text indicated that “different brain regions work together to support various cognitive processes” and “the functional specialization of different regions can change in response to experience and environmental factors” (OpenAI, 2023; see Appendix A for the full transcript).
