APA vs MLA vs Harvard: which referencing style does your department actually use?

One thing I noticed is that referencing style and its confusion causes more last minute panic than almost any other formatting issue, mostly because students realize halfway through chapter two that they have been citing sources inconsistently, or in a style that their department does not even use. If you need help on this, reach out to us on WhatsApp. If you want to continue reading this helpful post, let's continue to read together. Let's clear up the differences and how to figure out which one you actually need.

APA style

APA (short for American Psychological Association style) uses an author-date format in text, something like a name followed by a year in brackets, with a full reference list at the end organized alphabetically by author surname. This is the most commonly used style across social sciences, education, business, and many science departments in Nigerian universities, largely because it is clean, widely taught, and well documented online.

Harvard style

Harvard style is extremely similar to APA in its in-text format, also using an author and year approach, which is exactly why the two get confused so often. The differences show up mainly in the formatting details of the reference list, things like punctuation, capitalization rules, and how certain source types are structured. Many universities that say they use Harvard referencing are actually using a slightly localized version of it, so always check your specific department's example reference list rather than relying purely on general online guides.

MLA style

MLA, from the Modern Language Association, uses an author-page number format in text rather than author-date, and is far more common in humanities and literature focused departments, particularly English and some language departments. It is the least commonly required style across universities, but it is worth confirming directly if your course sits in this area, since assuming APA or Harvard when your department actually wants MLA is an easy mistake to make.

How to actually figure out which one you need

The most reliable way is to check your department's project writing guideline document, which most Nigerian universities issue to students, usually including a sample reference list you can follow directly. If you cannot find this document, ask your supervisor directly rather than guessing based on what a friend in a different department used, since referencing requirements genuinely vary even between departments in the same faculty.

Consistency matters more than perfection

Whichever style you end up using, the most important thing is applying it consistently throughout the entire document, not switching formats halfway through because you copied a reference format from a different source. Inconsistent referencing is one of the easiest things for a supervisor to spot, and one of the quickest ways to make an otherwise solid project look sloppy.

Using reference management tools

Tools like Zotero or Mendeley can automatically format your citations and reference list in whatever style you choose, and are worth setting up early if you are working with a large number of sources, rather than manually formatting each entry by hand and risking small inconsistencies creeping in across a long document.

Mistakes people make include:

I would like to recommend that you get your referencing style right and applying it consistently from the start of chapter two saves you a tedious, error prone cleanup process later. If you want your references properly formatted and checked throughout your project, my team at ProjectPal handles this as a standard part of the work we do.

Common questions

Questions students ask about this

How do I know which referencing style my department uses?
Check your department's project guideline document first, since APA, Harvard, and MLA are used differently across faculties, and using the wrong one is a common reason for formatting corrections.
What is the difference between APA and Harvard referencing?
Both use author-date in-text citations, but they differ in reference list formatting details, such as punctuation and how multiple authors are listed, so small details matter even when the overall style looks similar.
Should I use a reference management tool for my project?
It can help significantly with consistency, especially in a long document with many sources, though you should always double check the output against your specific required style.
