An in-text citation is a short note inside your sentence that credits the source of an idea, quote, or fact — right where you use it. It works together with the full reference in your bibliography: the in-text marker points the reader to the matching entry. Here’s how to use them correctly.
What an in-text citation looks like
The format depends on the style:
- APA (author–date): “(Susanto, 2023)” — and “(Susanto, 2023, p. 14)” for a direct quote.
- MLA (author–page): “(Susanto 14).”
- Numbered styles (IEEE, Vancouver): a bracketed number like “[3]”.
Place it at the end of the sentence (or clause) where you used the source, before the period.
When you need one
Add an in-text citation whenever you:
- Quote a source directly (use quotation marks too).
- Paraphrase or summarize someone’s idea — yes, even in your own words. Changing the wording doesn’t remove the need to cite; see paraphrasing vs plagiarism.
- Use a specific fact, statistic, or claim that isn’t common knowledge.
You don’t cite common knowledge (“water boils at 100°C at sea level”) or your own original analysis.
Quote vs paraphrase
- Direct quote: exact words in quotation marks + citation with a page number.
- Paraphrase: the idea in your own words + citation (usually no page number needed, though APA encourages one). Most of your citations should be paraphrases — they keep your voice consistent. See how to paraphrase a quote.
Every in-text citation needs a reference
The golden rule: each in-text citation must have a matching entry in your reference list, and vice versa. Build those entries consistently with the citation generator, and see our guides to citing sources and making a bibliography.
A quick workflow
- The moment you use a source, drop in the in-text citation.
- Generate the matching reference entry right away.
- Before submitting, check that every marker has a reference and the style is consistent — run a final pass with the grammar checker.
Cite as you write, keep one style, and in-text citations become automatic instead of a last-minute scramble.
