In order to avoid plagiarism, it is important to state clearly which sections or passages that are your own work (new primary research), and which sections or passages that refer to the works of others or your analysis thereof. Likewise, in order to avoid self-plagiarism, it is important to state clearly if you are using your own previously published work.



The definition of plagiarism is to use (i.e. mention, cite, refer, translate, analyse, interpret, discuss etc.) the text of someone else without making exact source references. In order to avoid plagiarism, the source reference must be precise to the extend that you can uniquely identify the original source.

Rules of thumb:

  • Avoid plagiarism by placing quotes in quotation marks and naming the source of the quote.
  • As soon as you use something that someone else has written or created, you must make a reference to the source.
