UGA now has access to a suite of Turnitin products for faculty and students, and are often embedded in UGA's G Drive.
View help materials for Turnitin Products here. Instructors have their own help page here.
If you just want information on how a certain style is organized, the UGA Libraries keep Citation Style Guide web pages with examples of how to cite the most common types of resources using the most common styles (APA, Chicago, MLA, and more!)
If you're using the Chicago Manual of Style (Author-Date) or Footnotes, you can access the entire manual online through GALILEO: http://www.galileo.usg.edu/express?link=mlal-uga1&inst=uga1
