Citing sources is an important part of your research.
It documents what sources you have used in writing your paper, gives credit to the author's work, and gives the information needed to identify and retrieve the cited sources.
Different disciplines or courses use different citation styles, so confirm with your instructor which style you should use.
There are many different citation managers available for your use including Zotero, Mendeley, and Reference Manager.
For more detailed information please consult the LibGuide, Which Citation Manager Is Best For Me?
