The search box on the Library's home page is a gateway to thousands of books.
To find print books (and some ebooks) in the library's collection, limit your initial search to Books+ (Library catalog). You may also conduct a search, and then limit your results to Resource Type books and then limit again to those "Available at the library". To find ebooks only, limit your search to resource type books and then limit again to those "Available online".
Call numbers tell you where a book is shelved. In the SJU Libraries, we use Library of Congress Classification which groups titles by subject matter.
The following call number ranges will help you get started. For books about a more specific topic, please search our catalog by keyword.
