APA Citation Guide (APA 7th Edition): When Information is Missing

Citing Sources with Missing Information

Citing Sources With No Author

If your source doesn't have an author, begin your citation with the title and date. Follow with the remaining citation elements required for your source. Don't use "Anonymous" unless this is what's indicated on your source.  

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.

Citing Sources With 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 collection. https://www.senecapolytechnic.ca/collection/

In-text Citation

(Seneca Polytechnic, n.d.)

Citing Sources With 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:

Reference List Citation

Vividata. (2018). [Potato chips - personally ate in the past 6 months for all respondents 14+ in Ontario]. http://library.senecapolytechnic.ca/res/vividata.html

In-text Citation

(Vividata, 2018)

Unknown Source

If you don't have a source, consider searching for a work which supports the information you are including in your assignment or essay.

You may also cite the information as personal communication if your source is a personal interview.
