You'll find that most topics with which you aren't familiar will use a special vocabulary--words or phrases that have come to be associated with the topic.
To become familiar with the vocabulary, you'll need to read at least one basic article about the issue. You might look at Wikipedia (but don't use it as a source in your paper).
Make a list, at least mentally, of the words or phrases that you can look for when searching for more information.
1. Look for background information (Check the databases listed below.)
2. Look for mention of people or reports that have studied the problem, and find those reports.
3. Find special terms that might be used to describe your issue, and use those terms in other searches.
