You will be using Chicago/Turabian style when citing the sources that you use in your research papers. The Chicago Manual of Style is available at the Dana Library Reference Desk. The Writing Center at the University of Wisconsin-Madison also has an excellent introduction to Chicago/Turabian Documentation. This will give you the basic information you need to create Chicago citations.
If you are a Rutgers student or a history major at NJIT, you can also import references from the Catalog and many of the electronic databases into RefWorks, or EndNote, two web-based bibliography and citation management systems. Citation management systems will store your citations and build your bibliography for you based on whatever style sheet you specify (MLA, Chicago, etc.).
For information on setting up a RefWorks account see the RefWorks FAQ.
