APA Style is widely used by students, researchers, and professionals in the social and behavioral sciences. The Scribbr APA Reference Generator automatically generates accurate references and in-text citations for free.
This referencing guide outlines the most important referencing guidelines from the 7th edition APA Publication Manual (2020). Scribbr also offers free guides for the older APA 6th edition, Vancouver Style, and Harvard Style.
APA in-text citations
The basics
In-text citations are brief references in the running text that direct readers to the full reference entry at the end of the paper. You include them every time you quote or paraphrase someone else’s ideas or words.
An APA in-text citation consists of the author’s last name and the year of publication (also known as the author-date system). If you’re citing a specific part of a source, you should also include a locator such as a page number or timestamp. For example: (Smith, 2020, p. 170).
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.

The basics
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.

Missing information
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.

The basics
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 word “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).
