A database is a collection of information. Most often, in a library, this means a collection of articles--scholarly journal articles, magazine articles, and newspaper articles.
Listed below are suggested databases containing articles on your topic. Since articles are shorter and more narrowly focused than books or reference materials, they are most useful after you have narrowed your topic.
You can also try a basic keyword search or browse topics.
Here's a tutorial that shows you how to log in to MDC databases and use one of our databases.
