How do I cite?
Different disciplines use different documentation styles. (See list of examples below or consult our printed style manuals, located at the Snell Library Reference Desk.)
Consult your instructor or publisher if you are not sure which one to use.
Is there software to help manage my citations?
Yes! Both EndNote  (provided by the University) and RefWorks  (provided by the University Libraries) are licensed for use by current NU faculty, staff, and students. Both of these programs help you collect and manage your references, and auto-format citations and bibliographies in your papers.
Which one should I use? In general, RefWorks is better for undergraduates and researchers needing to share references, while EndNote has a higher learning curve but more features and is better for graduate students, faculty and researchers with long-term in-depth research projects. We’ve created a more comprehensive comparison chart here .
Why do I need to cite?
Using footnotes, bibliographies, and similar strategies serves two main purposes:
1. It gives credit to the person who created the idea.
2. It allows your readers to locate the sources you used, therefore they can read or judge them for themselves.
