Citing your sources

How and when citing your sources.

Why and when should I cite?


  • respect copyright;
  • give credit to the author of the original work;
  • add authority to your work;
  • easily find sources;
  • demonstrate your search skills;
  • avoid plagiarism.

When should I cite?

  • paraphrasing someone else's idea;
  • taking a direct quote from a source;
  • referencing another person's ideas;
  • using data (statistics, graphics, etc.)
  • translating a text.

The same rules apply to electronic sources.

Public Notoriety

It is not necessary to quote a fact that is, in principle, known to all and can be found in various sources.

Ex.: The stock market crash of 1929.


Every reference cited must appear at the end of the document, in the list of references (bibliography). For more information, please visit our guide Bibliographie selon le style HEC Montréal. (in french)
