If you are interested in finding out what books and videos were added to the library catalog within the past academic year click on the Past Acquisitions button found on the New Acquisitions page. The categories are arranged in Library of Congress classification so you can find titles within your field of interest.
While this list of new library resources is useful, it does not include newly processed archival collections. Those can be browsed through the College and Lutheran Church Archives website at https://gustavus.edu/library/archives/.
