Try finding books on your subject using key words (such as "aggression" or "bullying"). Then, when you find a relevant book, click on subject headings in the book record that are related to your topic.
In addition, you can find many more books on your research topic by searching for these same subject headings (or key words) in WorldCat, a database containing catalogs of thousands of libraries. You can request books found in WorldCat through Interlibrary Loan, or visit other Memphis academic libraries and check the books out by presenting your U of M card. For more information, you can Ask a Librarian!
