The Publication Manual of the American Psychological Association, Seventh Edition is the official source for APA Style.
Changes in the 7th edition include:
- References can include up to 20 authors.
- Format your reference based on the document type, not the retrieval method. For example, format as a book regardless of whether you accessed it as a print book or ebook.
- Doi's should always be included and formatted as https://doi.org/xxxxx (highlighted and underlined as a link)
- Add a url if you found the work online, it doesn't have a doi, and the link works.
The Purdue OWL site provides numerous examples for citing various types of publications and it includes a sample paper illustrating the proper way to format a research paper and cite sources.
