If you are only interested in print books owned by Stevenson University, the easiest way to find them is to search in the library catalog. Using the advanced search, you can limit your results to "Circulating Books" or other types of books.
If you are searching in OneSearch, you can use the "Source type" option. Enter your search, then click the "Source type" dropdown menu and choose "Books" and/or "eBooks" (you may need to click the "+ more" link first to get all the different types of sources to show up):
Click the blue "Apply" button, and your results will include only books and/or ebooks.
