The Libraries has a comprehensive guide devoted to helping you with all parts of your research projects. From deciding on a topic to citing your sources, it very helpful, especially if you haven't done academic research before now.
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!)
A literature review discusses published information in a particular subject area, and sometimes information in a particular subject area within a certain time period.
If you've never written a Literature Review, or would like a refresher, UNC's Writing Center has a great explanation of the process.
The UGA Libraries also has an in depth introduction to doing Literature Reviews.
