You shouldn’t force yourself to remember everything because there are many citation styles and numerous kinds of sources. But memorizing the ones you use most is a good idea. The more references you generate with EduBirdie APSA citation machine, the better you’ll remember such basic rules as titles of sources like books, journals, magazines, and movies being in italics; names of articles and short stories being in quotation marks; placing conjunction between two names; using ‘et al.’ for many authors, etc.
