You can use the library's main search tool, OneSearch, to quickly find background information about the culture you chose. While books can be a good source of in-depth information on your topic, sometimes it's helpful to get a QUICK and SHORT encyclopedia entry - you can then take what you learn and search for more detailed information in articles (see the Finding Articles tab).
The screenshots below show you how to quickly access these encyclopedia entries on a topic. After searching for reggae AND culture (first picture), you can use the filters on the left to limit the results to "Reference Entries." This will show you (as in the second picture) the entries related to reggae in several encyclopedias that cover the topic of culture (notice the variety of encyclopedia titles highlighted in yellow boxes).
