APA vs MLA: Which Citation Style Should You Use?

One of the first questions every student asks when starting a research paper is simple: which citation style am I supposed to use? The two most common answers are APA and MLA, and although they exist to do the same job, crediting sources, they look and behave quite differently. Understanding the distinction early will save you hours of reformatting later.

What each style is for

APA stands for the American Psychological Association. It is the standard in the social sciences, including psychology, sociology, education, nursing and business. APA places emphasis on the year of publication because, in scientific fields, how recent a source is often matters as much as who wrote it.

MLA stands for the Modern Language Association. It dominates the humanities, especially English, literature, philosophy, languages and the arts. MLA focuses on the author and the page number, reflecting disciplines where close reading of a specific passage is common.

In-text citations: the clearest difference

The fastest way to tell the two apart is to look at an in-text citation. APA uses an author and date system, while MLA uses an author and page system.

The reference page

At the end of the paper, APA calls this list the References, while MLA calls it the Works Cited. In APA, only the first word of a title and any proper nouns are capitalised. In MLA, titles use headline-style capitalisation, where most major words are capitalised. APA puts the publication year right after the author, whereas MLA places the date toward the end of the entry.

Which one should you use?

The honest answer is that you usually do not choose. Your instructor, department or journal decides for you, and the requirement is normally stated in the assignment brief or syllabus. If you are genuinely unsure, ask, because submitting a paper in the wrong style can cost easy marks. As a rough guide, a science or social science course will expect APA, and an English or humanities course will expect MLA.
