Start with the Library Website
The library catalog, referred to as Mirlyn, enables you to search and browse the University of Michigan Library’s collection of books, journals, audio/video materials, electronic resources and more. It lists materials owned by the University Library (Ann Arbor), Clements Library, Bentley Historical Library, UM Transportation Research Institute (UMTRI), and UM-Flint.
The default search in Mirlyn on the UM Ann Arbor campus includes all of the Library's holdings in Ann Arbor as well those at the Biological Station in northern Michigan. You can change the libraries that are being searched by clicking on the drop-down menu next to "Search in" above the search box.
