Popular Citation and Reference Styles for Academic Writing

Citations and references show where ideas, data, quotations and supporting evidence come from. A consistent reference style also helps readers verify sources and helps journals or universities assess academic integrity.

Common reference styles

• APA Style is common in education, psychology, social sciences and behavioural research.
• MLA Style is often used in language, literature, humanities and text-based analysis.
• Chicago Style supports both notes-bibliography and author-date systems, depending on the discipline.
• Harvard Style is an author-date system used by many universities, with local variations in formatting.
• Vancouver Style is common in medicine, health sciences and numbered-reference journal articles.

Before sending a document for proofreading

Use one citation style consistently, check that in-text citations match the reference list, and confirm author names, years, page numbers, DOI links and journal details. For journal submissions, include the target journal guidelines so the proofreading can preserve both language quality and submission requirements.
