When you begin writing a research essay, you must take into account the format of your writing and reference pages. There are several reference styles that may be assigned to you, including MLA (Modern Language Association), APA (American Psychiatric Association), and Chicago. Each one has its own set of rules. No need to familiarize yourself with all 3 unless you have to, but you do need to master at least one if you’re in any field involving writing. Here are summaries of each style to help you start your essay on the right track.
