Whenever you quote or base your ideas on another person's work, you must document the source you used. Even when you do not quote directly from another work, if reading that source contributed to the ideas presented in your paper, you must give the authors proper credit.
Citations allow readers to locate and further explore the sources you consulted, show the depth and scope of your research, and give credit to authors for their ideas. Citations provide evidence for your arguments and add credibility to your work by demonstrating that you have sought out and considered a variety of resources. In written academic work, citing sources is standard practice and shows that you are responding to this person and adding something of your own. Think of documenting your sources as providing a trail for your reader to follow to see the research you performed and discover what led you to your own conclusions or contributions.
Here is a brief pamphlet with tips on how to identify and avoid plagiarism prepared by Kristyna Carroll, Research Support Librarian at Falvey Library:
Here are two short, entertaining, and informational videos about plagiarism:
Citations within your text link specific passages to the sources you consulted or quoted. This can be done through in-text parenthetic notes, footnotes, or endnotes. In addition, a bibliography or list of works cited is almost always placed at the end of your paper. The citation system and format you use will be determined by the citation style you choose:
