Any time you use someone else’s words, ideas, data, or creative work — even in your own words — you need to include an in-text citation. This shows where the idea came from and helps you avoid plagiarism.
You must cite the source whenever you:
-
Paraphrase or summarise an idea in your own words
-
Quote directly from a source
-
Refer to research, statistics, images, audio, video, or code
Citations usually go at the end of the sentence, before the full stop:
Paraphrased idea here (Cottrell, 2013).
If your sentence includes multiple ideas from different sources, you can cite mid-sentence — just make sure it’s clear which idea each citation refers to.
Tip: Every in-text citation must have a matching reference list entry.
