Q. How do I know which database to use?
Taking a look at the available databases related to your subject can be helpful. Clicking here provides a list that can be narrowed by subject. Simply click the drop-down menu, select the option most closely related to your topic, and then, click 'Apply.'
Another option, especially when you are just starting the research process, is to search across multiple databases at once. You can start with a Quick Search on the main page. Just type in your keywords (check the box next to 'Full Text' for ease of access) and click the 'Search' button. From the results that appear, it's likely that you may find which database(s) will be the most useful to you.
