Library databases can be a little tricky to use, but Google brings up a lot of sites that aren't reputable or academic. However, there's a tool that combines the scholarly content of library databases with Google's smart relevance ranking: Google Scholar.
Sometimes, articles that Google Scholar finds for you don't have the full text of the article free online.
Now consider this: Do a search on your topic in Library Search and Google Scholar. What similarities and differences do you notice?
