As in any other scholarly work, proposals also include a list of references. References show where readers can find the resources cited in the body text. The standard style guide for Royal Roads is the Publication Manual of the American Psychological Association, and depending when you started your RRU program, you'll use the sixth or seventh edition.
The RRU Writing Centre has extensive APA Style resources (see below in Resources), and if you're a RRU student, please contact us via the WriteAnswers contact form if you have any APA Style questions.
