The Summon Advanced Search on the library homepage is sometimes referred to as the "library Google search" because it will return a very large search results list. This list includes everything that MU Libraries owns that you have access to (either in print or online), as well as things that we don't own but think you should know about. It also allows you to select from many different options to narrow and/or refine your list of search results.
When searching in Summon, you will see many options on the left-side of the results screen for refining your results. For online students and faculty, it is wise to always narrow down your results by clicking on the Full Text Online link below the Refine Your Results heading.
