Citation

A citation is a formal reference to a source, whether a book, article, website, interview, or dataset, that credits the original creator and provides enough information for readers to locate the material themselves. Citations serve three essential functions in academic and nonfiction writing: they give credit where it is due, they allow readers to verify claims and explore further, and they position the writer's work within a larger scholarly conversation. Failing to cite sources constitutes plagiarism, one of the most serious breaches of academic integrity.

Citation styles vary by discipline. APA (American Psychological Association) style, dominant in the social sciences, uses author-date in-text citations and emphasizes the recency of research. MLA (Modern Language Association) style, standard in the humanities, uses author-page citations and focuses on the author's contribution. Chicago style offers both a notes-bibliography system favored in history and a author-date system used in the sciences. In The Craft of Research, Booth, Colomb, and Williams stress that citations are not mere formalities but rhetorical tools: citing a seminal study signals awareness of the field, while citing a recent article shows engagement with current debates.

When citing, prioritize primary sources over secondary ones whenever possible, and choose the most authoritative version of a source. Include enough information for the reader to find the exact passage you reference. Use citation management tools like Zotero, Mendeley, or EndNote to organize sources and generate formatted references automatically, but always review the output for accuracy. Most importantly, integrate citations into your prose naturally. A paragraph that is merely a string of citations with no synthesis or analysis suggests that the writer has collected sources without understanding them. Let your own argument lead, and bring in citations as evidence that supports, contextualizes, or challenges your claims.
