Plagiarism is an academic offense with potentially severe consequences at the University of Lethbridge. The University of Lethbridge Calendar (2013/2014) states it this way:
"No student shall represent the words, ideas, images, or data of another person as his or her own. This regulation will affect any academic assignment or other component of any course or program of study, whether the plagiarized material constitutes a part or the entirety of the work submitted (p.78)."
Perhaps think about it this way: how would you feel if someone used your ideas without acknowledgement?
Be sure to have a clear instruction from your instructor as to what style of citation to use to acknowledge your sources.
If no citation style is specified by your instructor, then consider using one of the standard citation styles: APA, MLA, or Chicago.
