Check against your own department's guide first — Harvard isn't one standard. Unlike APA, there's no governing body; every university publishes its own variant, and yours is the only one your marker applies.
After that, check consistency. Applying one format identically to every entry earns more marks than half-matching a guide you found online.
Why “correct Harvard” is a moving target
APA has an edition number and a manual. Harvard has a broad convention — author, date, then the rest — implemented differently by nearly every institution that uses it. One department wants Smith, J. (2024); another wants Smith, John (2024); a third italicises the journal and not the volume. None of them is wrong, and a generic online generator will confidently give you a fourth version.
So the first thing to find is your own library's referencing guide. It's usually one PDF, it's usually linked from the library homepage, and it settles every argument.
Cite Them Right (Pears & Shields) is the reference most UK libraries base their Harvard variant on, and most institutions subscribe to it. Ask your subject librarian — that's genuinely what they're there for, and it takes one email.
The five errors that actually cost marks
- A source in your list that's never cited in the text. Markers check this, and it reads as padding.
- An in-text citation with no matching entry in the list. The reverse, and it's worse — it looks like a reference you invented.
- Inconsistent punctuation across entries. Full stop after the year in some, comma in others. Individually trivial; across forty entries it reads as carelessness and it's what drops a band.
- Missing access dates on web sources. Nearly every Harvard variant wants one, and generators frequently omit it.
- Secondary citations passed off as primary. If you read Smith's account of Jones, you cite Smith. Citing Jones directly claims you read Jones.
A ten-minute manual check
Before any tool: sort your reference list alphabetically and read down the left edge only. Inconsistencies in author formatting jump out immediately when you're not reading the content. Then Ctrl-F each surname from the list in your document body — anything with zero hits is an uncited entry. Those two passes catch most of the five errors above.
Where a checker helps
What software is good at is the mechanical half: spotting an entry that's missing a required field, flagging punctuation that doesn't match the rest of your list, and catching citations with no matching reference. What it can't do is know which Harvard variant your department wants, or whether you actually read the source. Use it for the tedious pass and keep the judgement yourself.
If you're deciding between styles, see the difference between Harvard and APA. And if any of your references came from a chatbot, read this first — fabricated citations are a misconduct issue, not a formatting one.
