How to Cite Sources in APA Format?

Published by at February 6th, 2022 , Revised On February 5, 2024

APA is one of the most adopted referencing styles that are used among social science and humanities researchers. This article presents the most important and common citation guidelines from the APA 7th Edition Publication Manual (2020).

APA In-text Citations

The Basic Rules of Citation

In-text citation is a concise form of the reference that you used in your work. It provides sufficient background to clearly identify the source in the reference list. In APA, the in-text citation includes, author’s last name along with the publication year,

for example, (Johns, 2020, p. 199).

Parenthetical Vs. Narrative Citation

It is important to know the difference between these two forms of citations.

In parenthetical citation the author’s name and the date of publication should be written within parentheses,

for example, (Johns, 2020).

Whereas, in Narrative citation, the author’s name should be a part of sentence rather than written in parentheses,

for example, Johns (2016)

wrote that every person is fighting a battle within himself.

Multiple Authors and Corporate Authors

There is a slight difference in the citation format when citing a source with multiple authors/organisations.

The correct use of ampersand symbol and punctuation plays a very important role in it.

Type of Author Parenthetical Citation Narrative Citation
One Author (Johns, 2020) Johns (2020)
Two Authors (Johns & Robert, 2020) Johns and Robert (2020)
Three or More Authors (Johns et al., 2020) Johns et al. (2020)
Organisation (Solutions, 2020) Solutions (2020)

Missing Information

The below steps will guide you how to cite a source with missing date of publication or locator,

Missing Info What needs to do Parenthetical Citation
Author Add the source title. (Source title, 2020)
Date Use “n.d.” for “missing date” (Johns, n.d.)
Page Number Use an alternative locator or
skip the page number.
(Johns, 2020, Chapter 13) or
(Johns, 2020)

Use the same title formatting as used in the relevant reference entry (Make it italicized or, if the title is not italicized (in actual reference), then put it in quotation marks). Always use upper and lower case in the title.

APA Reference Page Formatting

The reference page consists of all the sources that you have used in your paper. The reference pages fall right under the main body of the paper just before the appendix. Put a bold and centered heading “References” at the first line of the page. Then start putting all references in alphabetical order. The references page should follow the below guidelines;

  1. Double spacing between references.
  2. Hanging indent of ½ inch.
  3. Font: Times New Roman 12 or Arial 11.
  4. Put page number at the right header.

Please note that only include those references that you have cited in the in-text citation throughout your paper. Do not include any irrelevant references.
