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 (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 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, 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.
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.
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.
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.
Assuming APA and Harvard are identical because their in-text citations look similar
Mixing referencing styles within the same document
Not checking the department's own guideline document before choosing a style
Formatting the reference list inconsistently, different punctuation or capitalization from entry to entry
Leaving all referencing until the very end instead of citing properly as you write
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.
