Use the Library Catalog to find books. Be sure to pay attention to the date and publisher of the book - the catalog does include older materials and primary sources.
Catalog Search results will include everything in the University of Michigan Library physical collection (books, audio, video, maps, musical scores, archival materials, and more), as well as materials available online such as electronic books, streaming audio and video, and online journals.
