Use the Tripod catalog for your home institution to look for all books (print and digital) owned by your college as well as the print titles at the other two schools.
The following searches are a sampling of possibilities. To find materials on a topic, try doing a keyword search in the Tripod Catalog to find relevant materials and then use the subject headings assigned to those titles to find more books. Note that all these searches are in the Books+Media channel. Combining search terms with OR is often a good strategy. It provides additional results that relate directly to your topic.
