Citing Sources in APA Style 7th edition: In-Text Citations

How to cite sources using APA style 7th edition.

In-Text Citations (also called Parenthetical References)

Whenever you use someone else's ideas in your own work, whether it be a direct quote or paraphrase, you must cite that source in your text. The in-text citation should include the authors last name, and year published, and should correspond with an entry in your references list.

Falsely balanced news coverage can distort the public's perception of expert consensus on an issue (Koehler, 2016).

Koehler (2016) noted the dangers of falsely balanced news coverage.

When to Include Page Numbers

If your paper has a direct quotation, you must also include a page number where the quotation can be found (see the Quotations page).

Although it is not required to provide a page number for a paraphrase, you may include one when it would help the reader locate the relevant passage in a long or complex work.

 

Specific examples from a source

If the passage in your paper refers to a quote, statistic, chart, or similar specific example from a source, indicate the page (or paragraph, web page section, chapter, figure, etc.) where the example is found.

Citing multiple works

When citing multiple works parenthetically, place the citations in alphabetical order, separating them with semicolons.

(Adams et al., 2019; Shumway & Shulman, 2015)

 

Citing a secondary source

If possible, find the original source, and cite that directly. If the original source is unavailable, provide a reference entry for the secondary source you used.  In the in-text citation, identify the primary source and then write "as cited in" and the secondary source you used.

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

 

Personal communication (in person & electronic)

Give the initial(s) and last name of the communicator, the words "personal communication", and an exact date as possible.
