You have lots of options when it comes to choosing a citation style. In many cases, your professor will tell you which style is preferred for your class or assignment. Modern Language Association (MLA), Chicago Manual of Style (Chicago), and American Psychological Association (APA) are the three styles most frequently used by students at The Claremont Colleges.
In general, citation styles vary by discipline:
MLA is used in the humanities
Chicago is common in business, history, and fine arts
APA is used in social sciences and some sciences
Many scholarly journals have their own preferred citation styles
When in doubt, check with your professor or your campus writing center
Citation managers like Zotero and RefWorks can help you manage and format your citations but they are not infallible: it's always a good idea to double check automatically-formatted citations before submitting your assignment.
Manage Your Research- Citation Managers
Citation managers "are programs that collect records or citations from research databases (indexes, catalogs, etc.) that you can then organize for your research projects. They also help you cite your research by creating bibliographies, citations, and footnotes automatically."
