You may want to go about searching for items in the BPCC Library Collection by looking for specific instances of a word or phrase in a title or, if you know a particular author who writes on your topic, you can search just those fields. Just select "Author" or "Title" before searching for your words or phrase.
There is also what we call a known item search, when you know a book exists and you are just checking the library to see if we have it or just trying to find it again, using the title and author searches will eliminate a lot of that scrolling and weeding that you would have to do with a keyword search. So, I wonder if we have an encyclopedia that deals specifically with culture.
That's a pretty good place to start.
