In this tab you'll find information about what where to start your research and what kinds of words to use in your search.
Google (and even Wikipedia!) is actually a great place to start your research, because you can find out a lot of useful background and contextual information on your research topic. When you have an idea for a topic you might want to research, check out Google to find out the who, what, when, where, and, why of your topic. You'll be able to do better research in a library database when you know more about your topic, and you get some ideas about some terms you might want to use in your search.
This video will give you some information about presearching (aka: doing background checks on your topic.)
