Use Google for research...
Google is not always the best tool for finding peer-reviewed scholarship or essays resting on quality sources, nor is it necessarily the best place to start your research. Google can, however, find relevant websites for new or cutting-edge topics that scholars have not yet addressed, official documentation from government agencies or institutions, or articles from online, open-access journals.
