The LUC Library Catalog is where you'll find a record of every book, e-book, set of books, and journal (by title) in LUC libraries. The Library Catalog also provides access to many but not all titles that LUC provides access to via subscription databases.

If you are looking to see if Loyola has a particular book, the best way to search is to go to the advanced search screen, then choose title from the first drop-down box and enter the book title (or pertinent keywords). Make sure that you are searching under the "Books, Articles & More" tab to ensure that you search all LUC libraries
