Managing citations isn't just a matter of making sure you are using the proper citation format for the authorities you use in cite arguments. It also means keeping track of the sources you've read in order to help you understand and synthesize their content, and logically arrange them so you can retrieve them when you need them.
Knowing the best tools that you have at your disposal to those ends and understanding how best to use them will be critical both as a student as a practitioner.
EndNote is a much more robust citation management program that you can use to keep track of your research and cite literature across many citation formats and automatically create bibliographies.
As is often the case with feature-rich software, EndNote may require a bit of getting used to, so I would recommend consulting this guide:

DePaul users can access EndNote from the university software page:
A free and open source citation manager that has simple browser plug-in compatibilities. Not as feature-rich as EndNote, but more user friendly and easier to integrate into a web-based research workflow.
