Avoiding Plagiarism
W hen writing a research paper, lab report or any other type of academic assignment, you will likely use resources such as books, articles and websites written by other people to support your argument.
However, when using someone else’s information, you must indicate where that information came from
(credit must be given where credit is due). If you fail to acknowledge your sources, you are guilty of plagiarism. Plagiarism is a serious offence which may lead to lost marks or a failing grade.
There are many different formats for providing credit (also known as bibliographic citation) to other sources within your research paper. This handout provides a brief summary of the APA style guidelines as outlined in the sixth edition of the Publication Manual of the American Psychological Association
(2010). The examples presented illustrate the more common types of bibliographic citation.
Please note that this handout should only be used as a guide. For complete information and additional examples consult the Library’s copy of the Publication Manual of the American Psychological Association.
PLEASE CHECK WITH YOUR INSTRUCTOR FOR ANY ADDITIONAL REQUIREMENTS THAT MAY
DIFFER FROM THOSE OUTLINED BY THE APA GUIDELINES, 2010 EDITION. YOUR PROFESSOR
MAY PREFER TO USE A DIFFERENT EDITION OF THE APA GUIDELINES.
