Plagiarism and Copyright

In the academic world it is essential to have a grasp of issues pertaining to plagiarism and copyright, issues that are often clouded in confusion. Here we give you the basics.

What is plagiarism?

To plagiarize means using somebody else's work and presenting it as your own without referring to the source. It may be a text, idea, theory, image, chart, figure, music, computer program or a product. Even reformulation, paraphrasing, text to your own words, without referencing the source is plagiarism. Plagiarism may also violate Copyright laws.

How do I avoid plagiarism?

  • Always refer and quote in accordance with good academic practice. You can read more about this on the page Citation technique and styles.
