Reference books are helpful for identifying key books and articles on a topic. You can search for more reference books in the Monroe Library Catalog.
Books on medieval history are often found in the call number range D111-203, which is located on the second floor of the library. To borrow books owned by Tulane University's library, you can ask for a TULU card at the Monroe Library desk. You can request an interlibrary loan for materials that the library does not own.
