This stage of your research is very informal: Google or maybe even (gasp) Wikipedia are sufficient to feel out ideas, because both are very user-friendly and don't require you to have a specific grasp of your search terms yet.
If you don't already know everything about your topic...good! Doing some initial research will help you come up with some possible directions and will also help you feel out your topic: have other people actually done research on it before that you can use as your sources? Has enough time passed for meaningful research to have been published? Don't make your research harder than it needs to be!
Remember to jot down KEYWORDS!! They are extremely useful when searching the library databases!!
