Personal Communications (emails & personal interviews)

Interviews & Emails

Interviews and emails are considered personal communications in APA style. They are cited within the text of your assignment, but do not get an entry on the references list. Put the citation right after a quote or paraphrased content from the interview or email.

 

Example

"Infections are often contracted while patients are recovering in the hospital" (J. D. Black, personal communication, May 30, 2013)

 

Example

Note: If the name of the person who was interviewed is mentioned in the sentence leading into the quote or paraphrased content, you do not need to repeat it in the in-text citation.

J. D. Black explained that "infections are often contracted while patients are recovering in the hospital" (personal communication, May 30, 2013).

Citing Sources with Missing Information

No Author: 

Example: Article from a print newspaper

Reference List Citation

Get on board for train safety. (2012, June 17). Toronto Star.

In-text Citation

Paraphrase: ("Get on Board," 2012)

Direct Quote: ("Get on Board," 2012, p. A14)


Note the capitalization of the title in the in-text citation. You may shorten long titles.

Example: Print book

Reference List Citation

Introduction to food science. (2018). ABC Press.

In-text Citation

Paraphrase: (Introduction to Food Science, 2018)

Direct Quote: (Introduction to Food Science, 2018, p.25)


If the title of the source is Italicized in the reference list citation, remember to Italicize the title in your in-text citation. You don't need to surround the title in quotation marks if the title is in Italics. Note the capitalization of the title in the in-text citation.

No Publication Date:

If your source doesn't have a date, write n.d. where you would normally provide the date.  For example:

Reference List Citation

Seneca Polytechnic. (n.d.). Seneca's art collectionhttps://www.senecapolytechnic.ca/collection/

In-text Citation

(Seneca Polytechnic, n.d.)

No Page Numbers:

If you're quoting from a source without page numbers, include the location where you found the information in your in-text citation. This includes the name of section/heading (if available) and paragraph number where you found the information. Count the paragraph from the beginning of the document or section (if available).

Although not required, APA encourages including the page number when paraphrasing if it will help the reader locate the information in a long text and distinguish between the information that is coming from you and the source.

Examples

(Diabetes Canada, n.d., Move More section, para. 2)

(World Health Organization, 2020, para. 10)

No Title:

 

If you're citing a source without a title, include a description of the work in square brackets. For example:
