The Pollak Library Catalog will allow you to search for print and online books on your topic.
Most of the books in the Pollak Library Catalog are scholarly, that means they can provide an overview of your topic. Sometimes you only need to read one chapter in the book, but each chapter includes a bibliography which can lead you to additional sources. Often, the chapter headings in the book can help you focus a large topic into a narrower research focus that can be explored in a smaller paper.
You can find scholarly books on your topic -- complete with useful bibliographies -- by conducting a keyword search in the catalog. Use the same keywords you'd use in any other database.
