How to Format Citations and References Correctly

Inconsistent references signal carelessness to reviewers and can trigger a revision request before the science is even assessed.

Know your style

The big four:

• APA — Author–date, common in social sciences and psychology.
• Vancouver — Numbered, standard in medicine and many life sciences.
• MLA — Author–page, used in the humanities.
• Chicago / IEEE / Harvard — Field-specific variants with their own rules.

Always use the style the target journal specifies, not the one you used last time.

In-text vs reference list

Two things must always match:

1. Every in-text citation has a corresponding entry in the reference list.
2. Every reference-list entry is cited at least once in the text.

Mismatches are the most common — and most avoidable — error.

Consistency beats perfection

Within a single style, pick a convention for edge cases (multiple authors, no DOI, preprints) and apply it everywhere. A reference manager helps, but always proof the output — automated tools introduce subtle errors.

Switching styles

Resubmitting to a new journal often means reformatting every reference. This is tedious and error-prone by hand.
