To search for books in the LSU Libraries, use Discovery or the catalog.
Discovery searches multiple resources, including the catalog and many databases, all at one time. Want better results? Try using one of Discovery's limiters, located in the left-hand column of your search results page.
You can also search in the catalog. If a URL link appears in a record, the book is available electronically. Records for print-only books will display a call number and the location "stacks." If you need help locating a book, consult a stacks directory near the elevators or ask a librarian.
Note that Discovery also searches the Hathi Trust Digital Library, a collection of 11 million digitized books from more than 50 major research libraries. Most of the books are out of copyright and therefore older, so this is a great place to search for primary sources.
