The Campus Library has a large collection of books and e-books (and other items, like periodicals and films) on topics related to popular culture. However, a keyword search in the catalog using just the first keywords that pop into your head is not likely to bring the best results. Finding the larger cultural and historical context of your topic on the free web can help you find vocabulary for the themes related to your topic. Searching for books on the themes and contexts can lead you to analysis of your topics in books. You'll want to check the index and tables of contents for references to your particular people or events.
