APA citation quick guide
APA Style is widely used by students, researchers, and professionals in the social and behavioral sciences. The Scribbr APA Citation Generator automatically generates accurate references and in-text citations for free.
This citation guide outlines the most important citation guidelines from the 7th edition APA Publication Manual (2020). We also offer a 6th edition guide.
APA in-text citations
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.
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.
|Author type||Parenthetical citation||Narrative citation|
|One author||(Smith, 2020)||Smith (2020)|
|Two authors||(Smith & Jones, 2020)||Smith and Jones (2020)|
|Three or more authors||(Smith et al., 2020)||Smith et al. (2020)|
|Organization||(Scribbr, 2020)||Scribbr (2020)|
When the author, publication date or locator is unknown, take the steps outlined below.
|Missing element||What to do||Parenthetical citation|
|Author||Use the source title.*||(Source Title, 2020)|
|Date||Write “n.d.” for “no date.”||(Smith, n.d.)|
|Page number||Either use an alternative locator or
omit the page number.
|(Smith, 2020, Chapter 3) or
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.
Citing a source starts with choosing the correct reference format. Use Scribbr’s Citation Example Generator to learn more about the format for the most common source types. Pay close attention to punctuation, capitalization, and italicization.
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.
|Missing element||What to do||Reference format|
|Author||Start the reference entry with the source title.||Title. (Date). Source.|
|Date||Write “n.d.” for “no date”.||Author. (n.d.). Title. Source.|
|Title||Describe the work in square brackets.||Author. (Date). [Description]. Source.|
Formatting the APA reference page
On the reference page, you list all the sources that you’ve cited throughout your paper. Place the page, right after the main body and before any appendices.
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).
