How to Cite Sources Correctly

In-text citations, paraphrasing and quoting — the basics that protect your marks.

7 min read · Written by UK academic writers

Quick Answer

You must cite a source whenever you use someone else's ideas, words or data, whether you quote or paraphrase. Correct in-text citation credits the original author, lets readers find your sources and protects you from accusations of plagiarism.

Citation is not just bureaucracy — it is how academic work shows its evidence and avoids plagiarism. Many students lose marks simply because they cite inconsistently or not at all. Here is what you need to know.

When You Must Cite

Cite whenever you use information that is not your own and not common knowledge: direct quotations, paraphrased ideas, statistics, images and specific findings all need a citation.

Quoting vs Paraphrasing

A direct quotation uses the original words in quotation marks with a page number. A paraphrase puts the idea in your own words but still needs a citation, because the idea is not yours.

  • Quote sparingly, for precise or memorable wording
  • Paraphrase to show understanding in your own voice
  • Both require a citation to the original source

Match Your Referencing Style

In-text citation format depends on your style: author-date in Harvard and APA, numbers in Vancouver, footnotes in OSCOLA. Use the style your department requires and apply it consistently.

Every Citation Needs a Reference

Each in-text citation must correspond to a full entry in your reference list, and vice versa. Mismatches are a common and easily avoided error.

Keep Track as You Research

Record full source details while you read, not at the end. Trying to reconstruct citations from memory the night before submission is how mistakes and accidental plagiarism creep in.

Key Takeaways
  • Cite all ideas, words and data that are not your own
  • Quote sparingly; paraphrase to show understanding
  • Both quoting and paraphrasing require a citation
  • Match the in-text format to your referencing style
  • Record source details as you research

Frequently Asked Questions

When do I need to cite a source?
