You can also find background information by searching the "Find Articles & More" search on the library homepage (link below). These short articles are mostly from online encyclopedias. If you need more ideas for background information, check out the entire research guide devoted to this topic, linked below.
You can also find books on your topic. As opposed to scholarly articles, books tend to deal with a topic more broadly (e.g. Popular Culture and American Society) and they can help you to refine your topic and find good keywords.
