The information given on this page is VERY basic. APA Style entails far more than simply getting citations correct. You must be aware of manuscript structure and content, the mechanics of style, and requirements for clear and concise writing. Your best plan of action would be to purchase the
Publication Manual of the American Psychological Association, 7th edition.
Or find the manual in a library (Call Number BF76.7 .P83 2020).
