There are two ways to find books in APU's online library catalog: you can browse books by subject categories (subject headings), or you can do keyword searches for books that use specific words or phrases.
Below, I've given you some suggested subject headings to start with (if you're interested in browsing), as well as some tips for keyword searching. Once you've found books on your topic, you can proceed to the next step: finding articles on your topic.
