A style manual provides direction on all aspects of the writing process, from the ethics of authorship to the word choice that best reduces bias in language. It also has examples of citations for different types of resources.
Many academic disciplines have their own style guide. Some journals even have their own specific style. Ask your professor what style they want you to use for your paper/project.
For more information, see the individual tabs for specific styles above, or use the printed style manuals shelved in the library's Research Commons.
The American Institute of Physics (AIP) is the standard citation style used in physics and some engineering courses.
