Getting a citation style wrong is one of the most common ways students lose easy points on a bibliography — not because the source is wrong, but because the formatting rules for author order, punctuation, italics and date placement differ between styles, and each field expects a specific one.
Which Style Does Your Field Use?
| Style | Common In | In-Text Citation Style |
|---|---|---|
| APA (7th ed.) | Sciences, social sciences, education, business | (Author, Year) |
| MLA (9th ed.) | Humanities, literature, languages | (Author Page) |
| Chicago (17th ed.) | History, and some publishing/trade writing | Footnotes, or (Author Year) |
| Harvard | Common outside the US, many UK/Australian institutions | (Author, Year) |
| Vancouver | Medicine and the life sciences | Numbered [1] |
What Actually Differs Between Styles
- Author name order and punctuation — "Smith, J." vs "Smith, John" vs listing first name first
- Date placement — right after the author (APA) vs at the end (MLA)
- Title capitalization — sentence case vs title case, and whether titles are italicized or in quotes
- In-text format — author-date parentheticals vs footnotes vs numbered references
Why This Trips People Up
The same source — say, a journal article — gets formatted completely differently depending on the style, and the rules aren't always intuitive (why does one style put the year right after the author, while another puts it at the end?). Getting even small details wrong across a full bibliography adds up, which is exactly the kind of repetitive, rules-based task that's easy to get consistently right with a tool rather than by hand.
What You Need to Generate a Citation
Regardless of style, gather the same core details first: author name(s), title, publication or publisher, year, and — for websites — the URL and access date. Once you have those, the correct formatting for any style is just a matter of applying its specific rules consistently.
Step-by-Step: Generate a Citation
- Enter the source's author, title, publisher/publication, and year (plus URL for websites)
- Choose the citation style your assignment requires
- Choose the source type — book, journal article, website, and others
- Get a correctly formatted citation, ready to drop into your bibliography
