This article covers how to cite in APA Style (7th ed.) when there are no known authors for a reference or when the author is unknown or cannot be reasonably determined. Before treating a reference as though it has no author, consider whether a group or organization (such as a government agency, association, nonprofit organization, business, hospital, task force, or study group) could be the author by checking the cover or title page.
APA 7th ed. uses the author-date citation system for citing references in-text. In parenthetical citations, this structure includes the author’s last name and the publication year (with a comma separating them) in parentheses. In narrative citations, the author’s last name is incorporated into the sentence. This formatting applies if your source has one author or if you are citing a source with multiple authors in APA.
Parenthetical citation for source with author:
(Author Last Name, Year Published)
Narrative citation for source with author:
Author Last Name (Year Published)
If a reference has an unknown author, the title of the work substitutes as the author name in the in-text citation.
No author, source title italicized:
(Source Title, year published)
(Park Avenue Summer, 2019)
No author, source title in quotes:
(“Source Title,” year published)
(“22 New Apple Varieties,” 1997)
Only use the capitalized word “Anonymous” in place of the author’s name when it’s overtly designated, not as a general substitute for a reference with an unknown author.
“Anonymous” as author name:
(Anonymous, year published)
To add a reference with no author to the reference list, first move the title of the reference to the author position in your citation. For further information on creating reference list citations, see this guide on APA citations.
Reference list examples:
Park avenue summer. (2019). Penguin Random House.
22 new apple varieties. (1997). Food Magazine. https://foodmag.com/article/1997/22-new-apple-varietites
If the reference is overtly signed “Anonymous,” then you can add the entry to the reference list as if “Anonymous” were the author’s last name.
Anonymous. (2020). Navigating the high seas. Sea Life. https://sealife.gov
Reference list entries without an author are alphabetized by the first significant word of the title.
Alphabetical order of reference list example:
Anonymous. (2020). Navigating the high seas. Sea Life. https://sealife.gov
Park avenue summer. (2019). Penguin Random House.
22 new apple varieties. (1997). Food Magazine. https://foodmag.com/article/1997/11/new-apple-varietites

How do I cite a source with no author or no date in APA?To cite a source with no author or no date in APA style, it is important that you know some basic information such as the title of the work, publisher if it is a book reference or volume and page details if it is a journal reference, and/or URL (uniform resource locator). The templates and examples for in-text citation and reference list entry of a book with no author and a book with no date are given below.
Book with no author
In-text citation template and example:
Books with no author in general, but not always, are given as parenthetical citations. If the book does not have an author, cite it by its title. If the title is too long, shorten the title in the in-text citation. Italicize the title in the in-text citation. Follow title case in the in-text citation even though the book title is in sentence case in the reference list entry. A parenthetical citation might look like this:
(Title of the Book, Publication Year)
(The Cultural Politics of Emotion, 2014)
Reference list entry template and example:
Title of the book. (Publication Year). Publisher.
The cultural politics of emotion. (2014). Edinburgh University Press
The title of the book is in italics and sentence case. While arranging the reference entry alphabetically in the reference list, arrange the entry by treating the title as author name. Remember that articles (A, An, and The), if present at the beginning of the title, should not be considered for alphabetization. When you have a numeral used in the title, consider it to be in the spelled-out form and arrange it accordingly in the reference list.
Book with no date
In-text citation template and example:
If you cite a book without a date, use “n.d.” in place of the year.
Author Surname (Publication Year)
Author Surname (Publication Year)
Reference list entry template and example:
Title of the book. (Publication Year). Publisher.
Cohen, J. (n.d.). Statistical power analysis for the behavioural sciences (2nd ed.). Lawrence Erlbaum Associates.

You need to set the title of the book in italics and sentence case. While arranging the reference entry alphabetically in the reference list, arrange the entry by treating the title as author name.
