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.
When you connect to Mirlyn, the default search is a exploratory, keyword search labeled All Fields. This will search for your word(s) or phrase(s) wherever they occur, and is a great way to get started with your catalog search.
You may also search by title, author, subject, academic discipline, ISBN or ISSN, journal name and call number stem. Use the pull-down menu to the right of the search box to change the search type. You may type multiple terms in the search box and combine them using AND, OR, and NOT (these combining terms must be capitalized).
The check boxes below the search box allow you to limit your results to items “Available online” (when at least one complete volume, issue, or part of the primary content is accessible online) or "Search only (no full text)" (items that have been digitized, but due to copyright restrictions, are not actually viewable/only searchable).
Some special considerations for AND, OR and NOT: in two word searches, Mirlyn automatically treats the two words as if there were an AND between them; results must include both words. In longer searches, AND must be added between each term if you want all of your results to include every one of your search terms. If you perform a three word search and you want Mirlyn to exclude two of your search terms, you must include NOT prior to each of the terms you'd like to exclude, or use parentheses as you would in algebra.
