APA In-text Citations

As a student or a research writer, you may have to work with the APA style. It is the most common citation style that is used throughout the social sciences. 

Citations ensure that your ideas are backed by reputable sources while giving credit to the original authors. So, how do we write proper citations in APA?

In this guide, we will walk you through the rules of APA in-text citations and make it simple for you. Whether you're new to APA format or just need a refresher, we've got you covered.

So let’s dive in!

APA In-text Citations 7th Edition: The Fundamentals

APA style uses the author-date citation system. That is, the source is referred to by its author and the year of publication. 

The in-text citation appears within the body wherever the source is quoted or paraphrased. These short citations guide the reader to its reference list entry, where complete information about the source is provided. Citations are essential in an academic paper to avoid plagiarism.

Here are the basics you need to know:

  • Location of In-text Citations:

The citations must be included whenever a source is used. It may be within the body of the text, tables, figures, or whenever you refer to a specific source. 

For instance:

The study's results were consistent with previous research (Miller, 2015).

  • Author-Date Format

The author's last name and the publication year are essential in an APA citation. They are enclosed within parentheses (parenthetical citation) or mentioned appropriately within the sentence (narrative citation). 

For example,

  • Parenthetical Citation

The results revealed a high correlation between the variables (Johnson, 2021)

  • Narrative Citation

According to Johnson (2021), the findings revealed a significant correlation between the variables.

  • Including Every Cited Work in the Reference List

Every work cited in the paper must have a corresponding entry in the reference list, and vice versa. This ensures that readers can easily locate the full publication details of any cited source.

Let's go in-depth into each of these parts.

When Should You Use In-Text Citations?

Understanding when to use in-text citations is essential for maintaining academic integrity. Citations should be placed immediately after the sourced material.

Let's explore the situations in which you should use in-text citations.

When You Quote Directly

Whenever you include a word-for-word quotation from a source, you should use an in-text citation to attribute it to the original author. The citation should include the author's last name, publication year, and the page number (if available) where the quote can be found.

Example: 

According to Johnson (2017), "Education is the passport to the future" (p. 42).

When You Paraphrase or Summarize

When you rephrase or summarize ideas, concepts, or findings from a source, you must acknowledge the original author. Even though you are using your own words, the ideas belong to someone else, and an in-text citation is necessary.

Example: 

Smith's research (2020) on renewable energy sources highlights their potential to mitigate environmental challenges.

When You Reference Specific Information

Whenever you refer to specific data, statistics, or facts from a particular source, you should provide an in-text citation. This allows readers to verify the information and explore the source further. You can present these facts or data either in text form or make tables and figures.

Example: 

The graph depicting population growth (Smith & Johnson, 2021) illustrates a steady increase over the past decade.

Expert Tip

The APA format discourages the use of footnotes for referencing. However, writers can use footnotes in some cases. Read our blog to learn how to use footnotes in APA.

How to Use In-text Citations 

In APA style, there are two primary ways to incorporate in-text citations: parenthetical citations and narrative citations. Both methods effectively attribute credit to the original sources, but they differ slightly in how they present the source. 

Let's explore how to use these two types of in-text citations.

Parenthetical Citations

Parenthetical citations involve placing the necessary citation information within parentheses at the end of a sentence or paragraph immediately after the cited material. 

Here are some APA in-text citation examples:

  • One Author

When a work has a single author, provide the author's last name and the publication year.

Example: 

Climate change is a pressing global issue that requires urgent attention (Johnson, 2021).

  • Two Authors

When a work has two authors, list both authors' last names with an 'and' symbol (&) between them and include the publication year.

Example:

The study found a significant correlation between diet and mental health (Lee & Brown, 2020).

  • Three or More Authors

When a work has three or more authors, use the first author's last name followed by "et al." (meaning "and others") and the publication year.

Example: 

The effects of the new treatment were promising (Williams et al., 2019).

  • Group or Organization as the Author

When the author is a group or organization, use the full name or acronym of the group in the citation.

Example:

International disease prevention guidelines suggest that cross-border travel should be carefully handled (WHO, 2022).

  • Multiple Sources by the Same Author and Year

Differentiate between multiple sources by the same author and year by adding lowercase letters (a, b, c, etc.) after the publication year in the in-text citation.

Example:

Several studies support this hypothesis (Smith, 2018a, 2018b).

  • No Author

For sources with no individual author or an anonymous author, use the first few words of the title in the in-text citation. Italicize the title and use quotation marks for articles, chapters, or web pages.

Example:

The article discusses various aspects of renewable energy ("Renewable Energy Sources," 2020).

  • No Date

If the publication date is not available, use "n.d." (meaning "no date") in the in-text citation.

Example:

The findings were consistent with previous research (Johnson, n.d.).

  • Include Page Numbers (if applicable):

When quoting directly from a source or referring to specific information on a particular page, include the page number in the in-text citation. Place the page number after the publication year, separated by a comma. 

Example: 

"The impact of technology on education has been widely understudied" (Miller, 2018, p. 25)

Narrative Citations

Narrative citations offer an alternative way to incorporate in-text citations, providing a more fluid approach to attributing sources within your writing. Unlike parenthetical citations, narrative citations integrate the author's name into the sentence, followed by the publication year in parentheses.

Let's explore the rules and examples of APA in-text citation format for narrative citations.

  • One Author

When the work has a single author, use the author's last name as part of the sentence and include the publication year in parentheses.

Example: 

Smith (2019) argued that this phenomenon is influenced by various factors.

  • Two Authors

For works with two authors, mention both authors' last names as part of the narrative, followed by the publication year in parentheses.

Example

Lee and Brown (2020) found a positive correlation between these variables.

  • Three or More Authors

When a work has three or more authors, include the first author's last name followed by "et al." (meaning "and others"), along with the publication year in parentheses.

Example: 

Williams et al. (2018) demonstrated the efficacy of this treatment method.

  • Group or Organization as the Author

Use the full name or acronym of the group as part of the sentence, followed by the publication year in parentheses. 

Example: 

The World Health Organization (WHO, 2021) issued a statement on global health challenges.

  • Multiple Sources by the Same Author and Year

Differentiate between multiple sources by the same author and year by adding lowercase letters (a, b, c, etc.) after the publication year in the narrative citation.

Example: 

Smith (2017a) proposed a groundbreaking theory in this field.

  • No Author

For sources with no individual author or an anonymous author, use the first few words of the title in the narrative citation. Italicize the title and use quotation marks for articles, chapters, or webpages, followed by the publication year in parentheses.

Example:

"Global Warming Effects" (2021) describes the impact of climate change on ecosystems.

  • No Date

If the publication date is not available, mention "n.d." (meaning "no date") after the author's name in the narrative citation.

Example: 

Johnson (n.d.) emphasized the significance of this discovery.

  • Including Page Numbers

When quoting directly from a source or referring to specific information on a particular page, include the page number after the publication year in the narrative citation.

Example: 

According to Miller (2016): Sensory memory, the initial stage of memory processing, holds sensory information for a brief moment after its perception. This allows for a continuous and seamless experience of the environment. However, only a limited amount of information transfers to the next stage, short-term memory. (p. 72).

  • Use Signal Phrases and Reporting Verbs

Signal phrases and reporting verbs can be employed to introduce in-text citations smoothly. Signal phrases indicate that you are referencing a source while reporting verbs attribute actions or ideas to specific authors.

Example:

  • Signal Phrase

According to Smith (2019), the study indicates a positive trend in consumer behavior.

  • Reporting Verb

Johnson (2021) argues that technology has revolutionized the way we communicate and connect with others.

Reference List

The reference list in APA provides a comprehensive list of all the sources you cited in your research. The list comes at the end of your paper, and it allows others to access and validate the information you used in your writing. 

The reference list follows specific formatting guidelines in APA style. Let's delve into the details of creating a well-formatted reference list. 

Basic Format

This is the basic APA format for a reference list:

  • The reference list begins on a new page, separate from the main body of your paper.
  • The title "References" appears at the center-top of the page.
  • All the sources cited or referenced in the paper are listed in alphabetical order by the authors' last names. If there is no author, use the title of the source as the first element.
  • Use hanging indent.

Formatting Different Types of Sources

An entry in the reference list presents necessary information about the sources. However, each entry is formatted differently based on its type. 

Here is how you format your entries in the reference list.

  • Books

Format: 

Author(s) Last name, Initials. (Publication Year). Title of Book. Publisher Name.

Example: 

Smith, J. A. (2021). The Science of Psychology: Exploring the Human Mind. Academic Press.

  • Journal Articles

Format: 

Author(s) Last name, Initials. (Publication Year). Title of Article. Title of Journal, Volume Number(Issue Number), Page Range. DOI or URL

Example:

  • Online Journal Articles without DOI

Format: 

Author(s) Last name, Initials. (Publication Year). Title of Article. Title of Journal, Volume Number(Issue Number), Page Range. URL

Example: 

Brown, S. M., & Johnson, K. L. (2018). Advances in Biomedical Research. Biomedical Journal, 5(1), 45-60. Retrieved from https://www.biomedicaljournal.com/article123

  • Edited Books or Anthologies
