I teach and support the bibliography application Zotero.
See my Zotero guide or ask me for help or information.
These are the main bibliographic styles used in Anthropology courses.
Ask at the reference desk of your campus library for print editions of the Chicago and APA style manuals.
These programs are like iTunes for citations: they give you one place to save your references, organize and search them, and automatically create bibliographies.
I prefer Zotero, but check out EndNote as an option too.
