How do you notate a report was written by someone else?

To notate that a report was written by someone else, you can include a citation or acknowledgment section. In academic or formal contexts, use a proper citation style (such as APA, MLA, or Chicago) to reference the original author. Additionally, you can include a statement in the report, such as "This report was prepared by [Author's Name] and compiled by [Your Name]." This clarifies authorship and ensures proper credit is given.
