In APA, what should be done if a source has no author?

When a source lacks an identifiable author, the correct action is to use the title of the work in place of the author's name in the citation. This practice is consistent with APA style guidelines, ensuring that readers can still locate the source despite the absence of an author. The title should be formatted according to the types of works cited—articles may use sentence case, while book titles should be italicized.

Using the title helps maintain the integrity of the citation process by allowing readers to trace the source material based on the provided information. This is crucial in academic writing, where proper sourcing enhances credibility and allows others to verify claims or explore concepts further. The other options do not adhere to APA guidelines; omitting the author entirely or labeling a source as "Anonymous" undermines the citation's effectiveness, while using "No Author" is not a recognized practice in APA formatting.
