3. Title of the source: Include the title of the article, book, webpage, etc. in italics.

4. Publication information: Include the name of the journal, book publisher, or website where the source was published.

5. DOI or URL: If the source has a DOI (Digital Object Identifier) or a URL, include it at the end of the reference.

The general format for an APA reference is as follows:

Author(s). (Year of publication). Title of the source. Publication information. DOI or URL

For example:
